New Audi A1 prototype testing





It seems that Audi has definitely decided to go after BMW's Mini, also some reports say that new A1 goes head-to-head with BMW 1 series. However it is obvious, Audi gonna come up with their new fighter for race in compact class.
If you ask me, these spy photos shows not much more than a pimped VW Polo, but there is no place for doubts that this is Audi's mule when you look at the licence plates, this prototype comes from Ingolstadt, Audi's home turf. What this will turn into we can expect to see at the upcoming Tokio Motor Show where Audi supposed to show conceptual look of the new A1; meanwhile we can play with PhotoShop
According to some reports, new A1 should debut at the 2009 Frankfurt Motor Show, but knowing that it is already under active engineering and prototype testing I wouldnt be surprised if it happens earlier.

Ronaldinho, Lionel Messi, Thierry Henry Test Drive Audi R8


As players of one of the world's best teams, Ronaldinho, Lionel Messi or Thierry Henry are not easily shaken. But whenever they receive the keys to their new cars from vehicle partner Audi the eyes of even these seasoned football stars start shining. Today was another such occasion: At the Circuit de Catalunya in Barcelona Ralph Weyler, Member of the Board for Marketing and Sales of AUDI AG, handed their new "company cars" over to the athletes. Audi and FC Barcelona have been partners since the past football season. The favourite product chosen from the sporty model range of the brand in Ingolstadt was again the Audi Q7.

Before the official hand-over of the vehicles in Barcelona, where the DTM is staging its penultimate race on Sunday, the footballers experienced the fascination of the Audi models in a special way: They had the chance to complete a few fast laps in the new Audi R8 sports car and proved to be as sporty as safe in their driving style. No wonder, after all, the two Audi factory drivers Mattias Ekström and Tom Kristensen had shared a few tips and tricks with the footballers. The favourite for the champion's title from Sweden and the seven-time winner of Le Mans accompanied the driver safety training which Audi had arranged for the players of FC Barcelona and chauffeured part of the team around the circuit in an Audi A4 DTM race taxi.

The footballers and the racers had already met the night before: Mattias Ekström and Tom Kristensen attended the Champions League home match of FC Barcelona against Olympique Lyon at Camp Nou, Europe's largest football stadium. "To watch this team play together with a crowd of 80,000 was an impressive experience," raved football fan Kristensen after the home victory.

Audi retires from Barcelona

DTM Barcelona: Scandal as Audi withdraw

A mass withdrawal from the DTM race at Barcelona by Audi overshadowed Jamie Green's maiden victory at the Catalunya circuit.

Audi management took the unprecedented step of withdrawing all of their cars after its principal title charges Martin Tomcyk and Mattias Ekstrom were involved in controversial crashes.

Audi Sport issued a statement claiming, "the Mercedes drivers used every opportunity to eliminate our cars."

The race began with Audi's Tomcyk on pole and he led Mercedes' Mika Hakkinen cleanly away at the start.

But what happened next between the pair was not so clean. Hakkinen caught Tomcyk's draught down the straight on lap six and was squeezed to the very inside of the first corner. Hakkinen braked too deep and the pair made contact, putting Hakkinen out and delaying Tomcyk.

Tomcyk's team mate and championship rival Ekstrom made his first pit stop around the same time leaving Mercedes driver in control of the race - Bruno Spengler leading from Bernd Schneider and Jamie Green.

Ekstrom's early pit stop left him battling in the pack and he caught Daniel la Rosa on lap 14. The pair were battling for position and when Ekstrom passed la Rosa on lap 14 he squeezed his rival off the track. La Rosa lost control on the grass and side-swiped Ekstrom's car, putting both out.

He later denied that he had continued to accelerate when he had been put on the grass and insisted that he had braked. But the stewards nonetheless penalised him and Hakkinen with fines and ten place grid penalties for the next race.

Tomcyk meanwhile was battling back through the field, moving up to seventh after his first pit stop but losing time running wide at turn one on lap 25. But he wasn't to last much longer - a problem with his battered car surfaced on his second pit stop and he subsequently retired.

That left Spengler looking at an open goal in terms of scoring championship points but he was delayed by a drive-through penalty. Schneider was eliminated with car failure which left Green poised to scoop his first ever win.

Further back the incidents continued. Spengler tried to pass Lucas Luhr around the outside but Luhr pushed Spengler wide and kept the position.

On lap 37 Mattias Lauda and Timo Scheider clashed, the contact sending Scheider's Audi into retirement. Temperatures were boiling on the Audi pit wall, but it was har do apportion blame for the collision.

The team finally snapped when Spengler passed Mike Rockenfeller on lap 46. Rockenfeller had defended his position very strongly and Spengler had gone up the inside of the Audi on the exit of La Caixa. The pair squeezed each other, contact was inevitable, and Rockenfeller was knocked across the gravel trap.

On the pitwall, Audi boss Wolfgang Ullrich had had enough. He ordered all remaining seven Audis directly into the pits to withdraw in response to the string of incidents. That ended the races of Rockenfeller, Luhr, Tom Kristensen, Alexandre Premat, Christian Abt, Markus Winklehock and Vaninia Ickx.

That left just six Mercedes circulating with Green leading. Paul di Resta, second, let Spengler past as per team orders but Green, as a first team driver, was spared the order and left to claim his maiden victory - although he clearly earned and wasn't involved in any of the controversy, it's likely that it will be somewhat overshadowed.

It remains to be seen what the consequences will be for the DTM - and Audi's participation in it - following this controversial twist.

Audi A5 receives two new engines


Audi, the German automaker continues to extend its A5 line. The recently launched A5 coupe receives now two new engines: a 3.2 FSI quattro and a 1.8 TFSI.

The 3.2 FSI engine helps the A5 to sprints from 0-100 km/h in 6.1 seconds while the top speed is electronically limited at 250 km/h. The 1.8 TFSI engine helps the coupe to sprint from 0-100 km/h in 8.4 seconds while the top speed is of 228 km/h.The average fuel consumption is of 9.2 litres in the case of the 3.2 FSI engine and 7.1 litres at the 1.8 engine.

Press release: 

Audi continues to extend its A5 model line, which has enjoyed a successful start: as of now, the sporty coupé is available with two new engine versions. The 3.2 FSI quattro allied with the six-speed manual gearbox is an especially dynamic source of power, while the 1.8 TFSI, also with manual shift, offers an extremely efficient alternative.

The 3.2 FSI, with its power output of 195 kW (265 bhp), is the most powerful engine in the A5 model line. The Audi engineers concentrated all of their expertise in this power unit, combining FSI petrol direct injection with the innovative Audi valvelift system for variable valve lift control and various measures for reducing internal friction. All this work has resulted in supreme refinement and impressive pulling power, with 330 Nm of torque available all the way from 3,000 to 5,000 rpm.

The 3.2 FSI gives the A5 performance figures worthy of a sports car. With this engine, the grand tourer sprints from a standstill to 100 km/h in 6.1 seconds, and its top speed is electronically governed at 250 km/h. The powerful coupé has an average fuel consumption of just 9.2 litres. The price of the Audi A5 3.2 quattro with manual gearbox is 44,200 euros.

Extremely high efficiency is the particular strength of the 1.8 TFSI. This four-cylinder engine, which is a new addition to the coupé model line, combines the benefits of the FSI principle with the advantages of turbocharging. These technologies together generate a power output of 125 kW (170 bhp). The peak torque of 250 Nm is available from as low as 1,500 rpm. The 1.8-litre engine comes with a manual six-speed gearbox and front-wheel drive.

With the powerful four-cylinder unit, the Audi A5 accelerates from 0 to 100 km/h in 8.4 seconds and reaches a top speed of 228 km/h. It sets excellent standards in terms of fuel consumption, limiting itself to an average of just 7.1 litres per 100 km. The A5 1.8 TFSI is available for 32,750 euros.

Audi to launch Q7 Hybrid in 2008


The Audi Q7 was the last SUV model to launch from the platform shared with the Volkswagen Touareg and Porsche Cayenne but it looks like it will be the first to launch a hybrid version. Automotive News is reporting that Audi will start production of the hybrid Q7 in late 2008, several months after introducing the new diesel models in the US market.

The hybrid system is being developed in conjunction with VW and Porsche. They have made the system modular so that it can be adapted to other vehicles in the product lineup. Porsche has already indicated that they will use the system on the upcoming Panamera sedan in addition to the Cayenne.

In the Q7 it will be paired up with a 3.6L V-6 and should yield about 23mpg. The electric part of the drivetrain will be able to drive the vehicle at up to 31 mph and the engine can be shut off at speeds up to 75 mph when coasting.

Abt Sportsline releases the Audi AS6 3.0L TDI


We're used to seeing plenty of highly modified petrol cars but every now and then a tuned oil-burner crops up. This time it's from the Bavarian-based Abt Sportsline, which has taken the wraps off its new AS6 3.0L TDI. The new car boasts a rare 100hp (75kW) per liter output, with a total 300hp (225kW) churned out by its 3.0L TDI mill. The maximum torque, which arrives at 4000rpm, is a staggering 600Nm.

The increases come from a series of upgrades including new engine management software and more boost from a custom Abt compressor. With the new performance numbers, the AS6 completes the 0-100km/h sprint in 6.9 seconds and a top speed of 249km/h.

Ensuring all that torque reaches the ground, engineers added a set of 20in wheels measuring 9in across. They also upgraded the brakes, added an adjustable suspension set-up and a complete bodykit. The latter consists of a set of side skirts, front spoiler and pumped fenders.

Audi R8 downed in Moscow



The Audi R8 isn't even on sale yet in most parts of the globe, but already we've heard of cars going up in flames in Germany and now we have a story about one that's gone amok in downtown Moscow. From the images, it appears the driver lost of control of the car in the wet weather, skidded across onto the median strip and then crashed into a small tree before spinning to a stop. The car must have been traveling at some speed because the crash managed to rip out the car's headlight out, projecting it several meters away onto a small patch of grass.

Every time we see a crashed exotic, we wonder when more car companies will start offering some kind of advanced driver training course as part of the car's purchase. Then again, there's no way to prevent the stupidity that makes someone want to speed in a built-up urban area in the wet. We hope the driver was at least smart enough to have insurance because it appears this R8 will have one very hefty repair bill.

600 New Employees for Audi

Audi is hiring young graduates in an effort to ensure the strong future of the brand. This year, the automaker is looking for 600 new employees.

German automaker Audi is making a bid to become the king of the mountain. Six hundred academics is the target for Audi. The young talents are there to unveil the new Audi RS6 - the company's most powerful production vehicle. Dr, Werner Widuckel, a Board Member for Human Resources at Audi AG, declared that the increase in their offering will mean more jobs in the future. Only motivated and dedicated employees will ensure company success and innovative power in the future," he said.

Most in demand are graduates in electrical engineering, mechatronics, mechanical engineering and automotive technology. Not only academics are attracted to Audi as an employer: 682 young people started their apprenticeships last week in Ingolstadt and Neckarsulm. Audi provides training in 20 different vocations.

"To a great extent, graduates want to identify with the products of their preferred employer. Factors such as market success and innovative power, interesting work and individual opportunities for development play an important role when choosing an employer," added Dr. Widuckel.

Last year, the automaker recruited 450 academics. The increase in the number of employees they are hiring shows the company responding to the need for engineers. The automaker is focusing on the employment of young engineers to develop highly-efficient diesel engines as well as alternative powertrains.

Preview: 2010 Audi A1 hatch and cabrio


The minicar segment is about to explode, with new models planned from most of the major carmakers including, for the first time, premium labels such as Audi, which is planning to launch the new A1 hatch in 2009. A concept version of the car will be displayed at next month's Tokyo Motor Show complete with a hybrid drivetrain. These new renderings give us an accurate look at what to expect, revealing designers are going with conventional hatchback styling and Audi's familiar oversized grille.

The A1 won't be a niche model. Audi management is hoping to sell more than 100,000 units per year and will likely add a 'shooting brake' mini-estate and cabrio to its lineup. Audi is also rumored to be working on a mini SUV labeled the Q1, which you can see a preview of by clicking here. In addition to the mild hybrid version, Audi will also build cars equipped with more conventional TSI and FSI petrol engines as well as its frugal TDI diesels displacing 1.4 and 1.6L.

The car will be built on a new platform that will also spawn the next-gen VW Polo as well as allow engineers to add quattro AWD for a low-volume performance model. The new platform also means engineers may add a new low cost dual-clutch transmission with seven gears in total. Unlike the production version of the VW up! concept, the Audi A1 won't be cheap and is expected to have a price tag of around €20,000. By contrast, VW's minicar is expected to cost close to €8,000.

2008 Audi R8 on tour around Canada


Audi has something good going on with the R8 supercar and they know it. The problem is, there isn't enough of them to go around. In order to make sure as many enthusiasts as possible get to lay eyes on the new machine, Audi is sending 15 journalists on a cross Canada jaunt from Cape Spear, all the way to the west, finishing up in Victoria, BC.

Friend of The Garage, Russ Bond from Painkillerz is lucky enough to be along for the section from Barrie, Ontario to Thunder Bay, Ontario. In fact, Russ is having a month filled with R8 goodness, having visited the press launch for the car last week and will spend next week with the press car. While Russ is on the road with the Audi R8 Trans-Canada Performance Tour, he'll be updating Painkillerz readers with daily photos and stories.

Frankfurt Motor Show: Audi A4 e Concept unveiled




With the new Audi A4 e Concept, the German automaker plans to show how its new Modular Efficiency program is. The new concept uses just 4.9 litres per 100 km. Also the Co2 emissons is just 129 g/km, that means less than the limit that will be introduced in 2012!

The 2.0 TDI in the new Audi A4 presents itself in an essentially enhanced form. A common rail injection system supersedes the unit injection pumps used to date, its piezo injectors supplying fuel with a pressure of up to 1,800 bar, allowing extremely fine atomisation in the combustion chambers. This improves fuel combustion and smooth running.

Press release:

With the new 2.0 TDI e Concept, Audi is showing just how effective its new Modular Efficiency program is. The sporty middle class saloon undercuts the consumption limit of five litres per 100 km. The A4 2.0 TDI e Concept needs just 4.9 litres for 100 km on the EU cycle. This means CO2 emissions of just 129 g/km – less than the limit that the European Union aims to introduce for vehicle fleets from 2012. With an output of 105 kW / 143 bhp and a peak torque of 320 Nm, the A4 2.0 TDI e Concept is a powerful saloon – for Audi, a dynamic character always goes hand in hand with low consumption.

In this vehicle, Audi has realised a whole package of innovative engineering solutions. Some of these are already in series production on the new Audi A4. Others, such as the start/stop system or the energy recuperation system, will be introduced in the near future.

TDI marries efficiency with dynamism

The 2.0 TDI in the new Audi A4 presents itself in an essentially enhanced form. A common rail injection system supersedes the unit injection pumps used to date, its piezo injectors supplying fuel with a pressure of up to 1,800 bar, allowing extremely fine atomisation in the combustion chambers. This improves fuel combustion and smooth running.

The refined engine develops a powerful 105 kW / 143 bhp of output. Even in the speed range between 1,750 and 2,500 rpm it puts a bullish 320 Nm of torque onto the crankshaft – this mighty pulling power at low revs is a one of the great strengths of the TDI principle. Modified piston geometry improves the thermodynamics in the combustion chambers. Other measures to reduce internal friction and for temperature management further increase fuel efficiency.

On the A4 e Concept, the 2.0 TDI engine is supplemented by the ultra low emission system. That means that this engine not only works highly efficiently, but it is also exceptionally clear and absolutely future-proof: Even today, it undercuts the strictest European emissions levels, which are not expected to come into force until 2014. The ultra low emission system, which makes the TDI the world's cleanest diesel, will go into series production in 2008 as an option on the new Audi A4 3.0 TDI.

Low-friction gearbox

The TDI's power is transmitted onto a newly developed six-speed manual gearbox that is characterised by greatly reduced internal friction. It has been specially tailored for the high-torque of the TDI engine – its transmission ratios are slightly longer in third to sixth gears. Like all Audi gearboxes, its gear changes are playfully light and extremely precise. The gear change indicator in the driver information system encourages an economical driving style. It indicates which gear is selected and if another gear is judged to be better while driving steadily, it will show this as a recommendation.

An especially fast and smooth start

Another important contribution is made by the start/stop system. It avoids the engine running inefficiently when the vehicle is stationary. This is important because much of our day-to-day driving is made up of trips that are shorter than ten kilometres, and these are interrupted by numerous stops at traffic lights.

As soon as the A4 2.0 TDI e Concept comes to a standstill, the gear lever is moved to neutral and the driver takes his foot off the clutch, the TDI is automatically switched off. The engine is restarted when the driver depresses the clutch. The TDI runs up while he is engaging the gear. It has reached idling speed by the time he releases the pedal. A specially developed starter motor turns the engine in little more than two tenths of a second – 60 percent faster than a conventional part, and yet especially comfortable acoustically.

Microhybrid gathers energy when coasting and braking

The recuperation system on board the A4 2.0 TDI e Concept converts kinetic energy into useful electrical energy as the vehicle decelerates. An innovative gel battery is used as the power source for the vehicle electrical system. This is extremely robust even at high loads and when it is heavily discharged, allowing it to achieve a particularly long service life.

When the A4 2.0 TDI e Concept is coasting or braking, the secondary voltage from the D/C converter is run up. The alternator is now able to convert the kinetic energy into electrical energy that is temporarily stored in the gel battery. When the saloon subsequently accelerates again, the battery feeds the energy back, relieving the load on the alternator.
The power steering has also been thoroughly modified – its effectiveness has been improved by around 50 percent because it is now fed hydraulic energy by a demand-controlled vane-cell pump. In contrast to conventional power steering pumps, which constantly recirculate large volumes, it only pumps as much oil as actually needed at that very moment.

On the automatic air conditioning system, Audi uses an innovative, thermostatically controlled refrigerant circuit with an internal heat exchanger. Along with intensive precision work on other components, has greatly improved the efficiency of the system – the new automatic air conditioning system requires 20 percent less fuel that its predecessor model did.

Sporty performance yet highly efficient

The A4 2.0 TDI e Concept glides smoothly and effortlessly through the wind. Its body is fundamentally extremely aerodynamic. Its boot lid has been given a slight additional separation edge. Specially designed alloy wheels improve the airflow across the wheels and wheel arches, while a sporty tuning has lowered the body by 20 millimetres. This modification reduces the frontal area, improving air resistance.

For Audi, efficiency means exactly the same as dynamics. For example, the tyres are configured for light running, but still have a sporty performance – they have the wide, visually attractive 225/50 R17 format. Yet the most impressive evidence of the potential of the A4 2.0 TDI e Concept is found in its performance figures. The middle class saloon sprints from 0 to 100 km/h in just 9.3 seconds. Its top speed is 215 km/h. A spurt from 80 to 120 km/h in 5th gear needs just 8.7 seconds.

Audi 2007 Melges 24 US National Champion: Record setting fleet set

In just over a week, some sixty Melges 24 skippers and crews will hit the waters of Lake St. Clair to decide who will be crowned the Audi 2007 Melges 24 U.S. National Champion.  With 56 entries received to date, and up to 8 more expected, this will be the largest U.S. Nationals in the 14 year history of the class – confirming the health of this ultra-competitive, high-octane One Design class.
 
U.S. Melges 24 Class President Scott Gregory and his Georgia-based Team Satisfaction were initially unable to make it to Bayview Yacht Club for the championship, but when the entry list hit 40 boats, they cleared their schedules. "We just couldn't miss an event like this up in Detroit," Scott said. "Those guys really get it – there are so many good sailors in the Detroit fleet, and they are the most enthusiastic group in the country.  They sail hard, they party hard, and they're always helping others improve.  We can't wait to get out there and mix it up."
 
Gregory and his team will have plenty of company.  Melges 24 events consistently draw some of the world's best sailors, and this one is no exception.  World Champion Dave Ullman, helming for Scott Holmgren on Rosebud, is clearly the favorite – but his challengers include some of the best in the business. Ullman's biggest obstacle is likely to be current North American Champion Brian Porter and his Full Throttle team.  Porter enlisted the help of two close friends from Lake Geneva to see if he can dethrone the legendary Ullman; Melges Performance Sailboats President Harry Melges III and VP Andy Burdick – both World Champs in the Melges 24.  Full Throttle was only seconds away from becoming the World Champion in Santa Cruz this past May when, on the final leg of the final race, a brutal gust of wind knocked her on her side, mast in the water.  Ullman's crew immediately dropped their spinnaker, giving them the control they needed to pass the disabled Porter and win the championship.
 
Star studded fleet includes World, National, North American champions
 
Other top sailors contending for the title of U.S. Champion include dozens of past Melges 24 champions at all levels.  Two-time World Champion Vince Brun will be on the course after a hiatus from the class, and other competitors of note include Bill Hardesty, John Pollard, Simon Strauss, Argyle Campbell, Mark Ivey, Michael Miller, Erik Shampain, and Bora Gulari.  Every one of these racers has the proven ability of a champion, as they've shown in everything from the Olympic 470 to the Transpac52.
 
Typical September winds on the lake are gusty and shifty, and local knowledge could prove to be the key to a solid result.  Local stars include up-and-coming match racer Nate Hollerbach, who heads off to Bermuda in a few weeks for one of the premier match racing events in the world – the Gold Cup.  Hollerbach is honing his skills on the helm of Zig Zag, although he'll have some very motivated opponents on the water:  Squaring up against Nate are his father, Marc and brother, Adam aboard Fu.
 
Penalty Box Productions to produce championship DVD
 
Event Chairman Paul Hulsey was pleased to announce yesterday that he had retained high-performance race filmmaker Peter Crawford's Penalty Box Productions to film the event. "With this many competitors, and the likelihood of solid breeze, it would be horrible to miss out on high quality video coverage," Hulsey said.  Crawford, a lifelong scow and iceboat sailor, has an eye for fast racing machines, as he proved with amazing footage from the windy 2007 Worlds in Santa Cruz.  Each team will receive a short DVD of the event, and interested parties can pre-order a full-length DVD that includes both the Worlds and National Championship footage.

Audi 2007 Melges 24 U.S. National Championship 
The Audi 2007 Melges 24 U.S. National Championship is hosted by Bayview Yacht Club, with the support of Sponsor/Partners Audi of America, Inc., the Detroit-Area Audi Metro Dealers, Barefoot Wines, Yachtscoring.com, Latis Yachting Solutions, the Detroit Medical Center's Rehabilitation Institute of Michigan, Rock City Marine, Tim Wilkes Photography, and Penalty Box Productions.
  
The Melges 24 is the most unique one-design sportboat in the world, and one of the fastest-growing one-design race classes in the world.  More information on the U.S. Melges 24 Class is available at www.usmelges24.com

Exotic Audi R8 outshines stars

Until I spent a long weekend with the Audi R8, I didn't realize just how many camera phones there were in the city of Toronto.
Having been cellphone shopping only a few weeks before my R8 experience, I knew that camera phones were quite popular. But my, oh my, they're everywhere.
They're in your side-view mirror, hanging out of cars sitting in your blind spot on the Gardiner Expressway, trying to get some footage of you accelerating away.
They're staring at you through the back window of cars in front, panning back and forth to take in the full magnificence of the R8's LED driving-light arrangement and its big, low shield-shaped grille.
They're poking out from crowds at bus shelters, snapping a pic as you drive by. They're right in your face as you come back to the car in a parking lot, hoping to sneak away and avoid any lengthy conversation.
I've driven more expensive cars than the Audi R8. I have driven faster cars and cars that make more noise and cars that go around corners faster. But I have never driven anything that draws quite so much attention.
The Toronto International Film Festival opened the same day I picked up the R8. On my drive home from work through the entertainment district, onlookers peered into the gunslit-shaped side windows, hoping to catch a glimpse of celebrity and instead got an eyeful of fat Asian auto journalist – not old enough or thin enough to be Chow Yun-Fat and not in good enough shape to be Jackie Chan.
One guy, I kid you not, even asked for my autograph, even though he didn't know who I was. The car was enough, he said; he'd glimpsed it parallel-parked on Richmond and had circled the block to take a closer look. Is this what celebrity feels like?
Such adulation from the masses comes at a price, of course, but perhaps not as high a price as you might expect.
Oh sure, $139,000 to start (my tester listed at just over $150,000) is a big chunk of change in anybody's book. But curbside speculators always guessed high on the price scale.
Perhaps it's the R8's proportions, which are long, low, wide and eerily reminiscent of the Lamborghini Gallardo with which it shares a little bit of DNA.
Perhaps it was the detailing: delicate double-spoke alloys that barely wrapped around huge brake calipers bearing R8 logos, rear lights that looked like neon-outlined TV screens, that contrasting panel of silver on the side of my gray test car.
Perhaps it's the specifications: 420 horses from its dry-sump, direct-injection V8, six speeds, four-wheel drive, only two seats.
Perhaps it's the technology: magnetic ride-control suspension, GPS navigation, optional F1-style paddle shifters.
The darn thing looks high-tech, too, a combination of its tall windshield, jeweled lights, the vents cut into those side panels and the mesh-inset rear wing that automatically rises at 110 km/h. "One-forty?" people gawped. "It looks like should be two-fifty!"
One-forty it is, though, making Audi's most direct target the Porsche 911 Carrera 4S, which stickers at about $10,000 less than the R8 but is about the same when equipment is evenly matched.
Curious about the reaction the R8 would get, I took it to an informal gathering of Porsche and Corvette enthusiasts that meets every Saturday in the parking lot of a suburban coffee shop. It was, not surprisingly, the star of the show, swarmed by interested would-be owners who loved its design, its interior and the sound its V8 made.
The only disappointment, really, seemed to come from the fact that all of next year's allocation of 100 cars is already sold out, making R8 ownership an unlikely proposition even for people who can afford it. It's all part of Audi's plan to keep the car exclusive enough to stay special.
In terms of the way the R8 compares behind the wheel, the Porsche has its advantages and it has its disadvantages.
The main difference is that the 911 feels smaller once you're on the move. Its narrower body, more upright seating position and larger glass area make it easier to thread through traffic and along winding roads with precision.
The Audi, despite being incredibly nimble and light on its feet, always feels like a big car: its width makes squeezing into tight parking spots a chore, even when using the reversing camera, and you always second-guess yourself about whether you can thread through any given piece of pavement.
While their power-to-weight ratios and acceleration times are close enough to be almost equal, the Audi can feel faster and more powerful in everyday situations, thanks to the fat spread of torque from its V8.
While the R8 redlines at over 8000 r.p.m., it delivers plenty of low-end punch even at 2000; the Porsche needs to be revved harder and often requires a downshift when the Audi doesn't.
Braking performance is about equal; the C4S has six-pot calipers up front while the Audi has eight, but both drag the cars to a drama-free stop in a minimum distance. Likewise, both all-wheel-drive systems are strongly rear-biased, shuttling power up front when needed without inducing understeer in corners.
One area where the 911 has an advantage is steering feel. While both cars corner flat and true – and both, interestingly enough, also bob their noses a little bit in fast curves – the Audi's steering can feel heavy and a little bit numb while the 911's three-spoke wheel dances under your fingertips.
Ultimately, this leads to a greater sense of confidence, even if the Porsche's rear-engine layout means it'd be trickier to drive at the limit than the smoother-transitioning mid-engined Audi.
On the other hand, the R8 is vastly more comfortable as a daily driver: even in the supposedly-stiff sport mode, it rides better than the 911 and, in comfort mode, is as composed as any sedan.
The R8's cabin feels much wider and, except for a dead pedal that was too close for my taste, the layout is near-perfect, with easy-to-decipher controls and displays right where you would expect them.
Even though a lot of the parts in the R8's interior come from other Audis – the steering wheel, door handles, climate control knobs and other bits come from the TT, for instance – it's hard to deny the sense of occasion you feel dropping into its low, low cabin.
The view out the windshield is spectacular. The cockpit sweeps around the driver, the gauges float in chromed triangular pods and the navigation screen swivels away at the touch of a button so you can load discs and memory cards.
Choose the manual transmission and you get an exposed shift gate like a vintage Ferrari's; even moving around a parking lot, you get a clack-clack sensation to remind you that you're driving something special.
There are other theatrical touches as well. When you unlock the R8 with the keyfob, not only is the interior lit up, but so is the glass-covered engine bay, cool blue xenon exposing the V8 for the world to see.
Flick on the headlights and you discover subtle little R8 logos in the headlamp lenses; the driving lights are a row of LEDs that curve under the main beams, sort of an automotive form of mascara.
Inside, the gauges flicker on and all the needles do a full sweep before settling into their proper positions; the navigation system even has a cool R8-branded startup screen.
Under way, you're treated to one of the world's greatest engine notes, a magnificent high-tech rumble from the quad pipes; think Pavarotti singing thrash metal.
Properly executed downshifts are greeted with a sharp bark from the exhaust and you hear the odd screech of tire before the lenient stability control reins in the fun in tight corners.
It is, ultimately, the sense of theatre, combined with genuine everyday ability, that makes the R8 such an interesting proposition.
It's as practical as a 911 – save for the Porsche's tiny rear seats – but looks so much more exotic.
It's as comfortable as a luxury sedan but exudes so much more drama, whether you're sitting still in traffic or roaring along the left lane of the expressway.
It's a car with the visual presence of an Italian supercar, with a generously sized trunk, decent behind-the-seats storage and unflappable build quality.
It is beautiful to behold and a delight to drive, one of the very best performance cars you can (more or less) buy. And, at least for now, definitely the coolest.

Preview: 2009 Audi S7


Audi is preparing a new four-door coupe positioned between its A8 limo and A6 models and, as with any new Audi, there's invariably a performance "S" model. Aimed at the segment starter, Mercedes' svelte CLS saloon, the new A7 should arrive on the market in early 2009 and will be joined by a convertible version one year later.

Standard models will get the usual assortment of FSI and TDI six and eight cylinder engines but a new top of the line S7 is tipped to get the naturally aspirated 5.2L V10 engine from the S6. The S7 will also benefit from Audi quattro and the carmaker's new sport differential torque distribution set-up.

Depending on the success of the car, there could even be a new super-saloon in the form of a RS7 powered by the new 580hp twin-turbo engine that debuted in the new RS6.

These new renderings of the car reveal designers won't be making any drastic changes to Audi's current design language, with the new S7 taking many cues from the S5 and S4 models. One of the new themes set for Audi's performance models is the clean front end, devoid of any fog lights, and it appears this will carry for the future S7 as well.

Frankfurt: Audi shows its new A4, with a green concept before


Just as Audi's cousins at Volkswagen have their BlueMotion range of models (as well as the ECO2 from Renault or the ECOnetic from Ford, just to name a couple), Audi is introducing a low-emission concept in Frankfurt, called e Concept. The picture shows the presentation of the 2008 A4.

The model is based on the current 2.0 TDI engine (which I think is the best-seller at the VAG group in Europe). The car has an impressive consumption for a compact sedan of about 4.9 liters/100km (48 MPG) and CO2 emissions under 129 g per km, which is less than the average the EU plans to become mandatory in 2012. The engine is good for 143 HP at a peak torque of 320 Nm (236 ft lb).

Audi manages those respectable figures by installing piezo-electric injectors in the engine and modified piston geometry to improve thermodynamics and reducing internal friction. To make it the cleanest diesel available, Audi added an ultra low emissions system which will be standard on the 2008 3.0 TDI engine. This engine meets mandatory regulations expected from 2014.

The car has a lower friction manual gearbox with longer rations from third to sixth gears as well as a new Start/Stop system that shuts the engine off when the car comes to a standstill and the driver presses the clutch. Once the driver releases the clutch to start, the engine comes back to life in less than two tenths of a second.

In addition to that, the car stores kinetic energy into gel batteries, making it a micro-hybrid although this energy is used only to power the alternator, so the car saves some energy from the engine at coasting or higher demand (like BMW). Since it's not only the engine that creates pollutants in the car, the A/C system uses a heat exchanger which saves 20 percent of fuel.

Finally, the A4 has some aerodynamic tweaks such as lowering the body about 20mm and installing better wheels.

The world's cleanest diesel in the new Audi A4 and in the Audi Q7More powerful yet more efficient – the latest generation hybrid module
More dynamism with less and less fuel consumption – Audi is pursuing a consistent strategy to achieve further reductions in emissions. With three concepts that are virtually ready for series production, Audi is using the IAA to present the technology of the near future. The new A4 2.0 TDI e Concept consumes just 4.9 litres of fuel for 100 kilometres, and thus represents a milestone in the sporty middle class. The world's cleanest diesel engine will enter series production in 2008 in the new A4 3.0 TDI with ultra low emission system. The latest generation of hybrid module makes use of the superior parallel hybrid construction and of state-of-the-art technologies such as lithium ion batteries.

Just 129 grams of CO2 – the 2.0 TDI e Concept
With the new 2.0 TDI e Concept, Audi is showing just how effective its new Modular Efficiency program is. The sporty middle class saloon undercuts the consumption limit of five litres per 100 km. The A4 2.0 TDI e Concept needs just 4.9 litres for 100 km on the EU cycle. This means CO2 emissions of just 129 g/km – less than the limit that the European Union aims to introduce for vehicle fleets from 2012. With an output of 105 kW / 143 bhp and a peak torque of 320 Nm, the A4 2.0 TDI e Concept is a powerful saloon – for Audi, a dynamic character always goes hand in hand with low consumption.
In this vehicle, Audi has realised a whole package of innovative engineering solutions. Some of these are already in series production on the new Audi A4. Others, such as the start/stop system or the energy recuperation system, will be introduced in the near future.
TDI marries efficiency with dynamism
The 2.0 TDI in the new Audi A4 presents itself in an essentially enhanced form. A common rail injection system supersedes the unit injection pumps used to date, its piezo injectors supplying fuel with a pressure of up to 1,800 bar, allowing extremely fine atomisation in the combustion chambers. This improves fuel combustion and smooth running.
The refined engine develops a powerful 105 kW / 143 bhp of output. Even in the speed range between 1,750 and 2,500 rpm it puts a bullish 320 Nm of torque onto the crankshaft – this mighty pulling power at low revs is a one of the great strengths of the TDI principle. Modified piston geometry improves the thermodynamics in the combustion chambers. Other measures to reduce internal friction and for temperature management further increase fuel efficiency.
On the A4 e Concept, the 2.0 TDI engine is supplemented by the ultra low emission system. That means that this engine not only works highly efficiently, but it is also exceptionally clear and absolutely future-proof: Even today, it undercuts the strictest European emissions levels, which are not expected to come into force until 2014. The ultra low emission system, which makes the TDI the world's cleanest diesel, will go into series production in 2008 as an option on the new Audi A4 3.0 TDI.
Low-friction gearbox
The TDI's power is transmitted onto a newly developed six-speed manual gearbox that is characterised by greatly reduced internal friction. It has been specially tailored for the high-torque of the TDI engine – its transmission ratios are slightly longer in third to sixth gears. Like all Audi gearboxes, its gear changes are playfully light and extremely precise. The gear change indicator in the driver information system encourages an economical driving style. It indicates which gear is selected and if another gear is judged to be better while driving steadily, it will show this as a recommendation.
An especially fast and smooth start
Another important contribution is made by the start/stop system. It avoids the engine running inefficiently when the vehicle is stationary. This is important because much of our day-to-day driving is made up of trips that are shorter than ten kilometres, and these are interrupted by numerous stops at traffic lights.
As soon as the A4 2.0 TDI e Concept comes to a standstill, the gear lever is moved to neutral and the driver takes his foot off the clutch, the TDI is automatically switched off. The engine is restarted when the driver depresses the clutch. The TDI runs up while he is engaging the gear. It has reached idling speed by the time he releases the pedal. A specially developed starter motor turns the engine in little more than two tenths of a second – 60 percent faster than a conventional part, and yet especially comfortable acoustically.
Microhybrid gathers energy when coasting and braking
The recuperation system on board the A4 2.0 TDI e Concept converts kinetic energy into useful electrical energy as the vehicle decelerates. An innovative gel battery is used as the power source for the vehicle electrical system. This is extremely robust even at high loads and when it is heavily discharged, allowing it to achieve a particularly long service life.
When the A4 2.0 TDI e Concept is coasting or braking, the secondary voltage from the D/C converter is run up. The alternator is now able to convert the kinetic energy into electrical energy that is temporarily stored in the gel battery. When the saloon subsequently accelerates again, the battery feeds the energy back, relieving the load on the alternator.
The power steering has also been thoroughly modified – its effectiveness has been improved by around 50 percent because it is now fed hydraulic energy by a demand-controlled vane-cell pump. In contrast to conventional power steering pumps, which constantly recirculate large volumes, it only pumps as much oil as actually needed at that very moment.
On the automatic air conditioning system, Audi uses an innovative, thermostatically controlled refrigerant circuit with an internal heat exchanger. Along with intensive precision work on other components, has greatly improved the efficiency of the system – the new automatic air conditioning system requires 20 percent less fuel that its predecessor model did.
Sporty performance yet highly efficient
The A4 2.0 TDI e Concept glides smoothly and effortlessly through the wind. Its body is fundamentally extremely aerodynamic. Its boot lid has been given a slight additional separation edge. Specially designed alloy wheels improve the airflow across the wheels and wheel arches, while a sporty tuning has lowered the body by 20 millimetres. This modification reduces the frontal area, improving air resistance.
For Audi, efficiency means exactly the same as dynamics. For example, the tyres are configured for light running, but still have a sporty performance – they have the wide, visually attractive 225/50 R17 format. Yet the most impressive evidence of the potential of the A4 2.0 TDI e Concept is found in its performance figures. The middle class saloon sprints from 0 to 100 km/h in just 9.3 seconds. Its top speed is 215 km/h. A spurt from 80 to 120 km/h in 5th gear needs just 8.7 seconds.
Just 119 g/km CO2: the Audi A3 1.9 TDI
Audi models with the letter e unite efficient energy use with high dynamics. The Audi A3 1.9 TDI e and A3 1.9 TDI e Sportback achieve a standard fuel consumption of just 4.5 litres per 100 km and CO2 emissions of just 119 grams per km. And yet the two models with an output of 77 kW (105 bhp) have a top speed of 194 km/h.
In the near future, Audi will vastly expand the range of such especially efficient models, offering e-models as TDI, FSI and TFSI in the high-volume model series. The Audi A4 2.0 TDI e Concept shows what such a concept could be in the new A4 model series. By the year 2012, Audi will have reduced the CO2 emissions all from its models by around 20 percent and in doing so have bolstered their sporty, sophisticated character even further.
The cleanest diesel in the world
With the new Audi A4 3.0 TDI with ultra low emission system, Audi is demonstrating the future-proof potential of the high-tech TDI engine. From mid-2008, the cleanest diesel in the world will be available in the sportiest saloon in the middle class. It fascinates not only with the dynamics of its 176 kW / 240 bhp and outstanding peak torque of 500 Nm, but also with its low fuel consumption figures and extremely low emissions.
Right from the very start, the A4 3.0 TDI with ultra low emission system will satisfy the emissions limits due to come into force in Europe from 2014, and the LEV II BIN 5 standard valid in the USA. The cleaning effect of the system is also seen in the levels of NOx nitric oxides, which have been reduced by 90 percent. And yet it works more effectively than any other technology on the market.
Audi is not starting its systematic TDI strategy in the second half of 2008 on the A4 alone. The Audi Q7 will then also be available with the world's cleanest diesel engine. Here peak torque will be an amazing 550 Nm. Additional models will quickly follow. By 2010, Audi plans to offer the new technologies in other vehicles segments and power classes.
Innovative technology for minimum emissions
The engineers in diesel engine development at Audi have combined a whole package of innovate measures for this latest TDI generation. The new piezo common rail system with an injection pressure of 2,000 bar, highly efficient exhaust gas recirculation and the optimised turbocharger produce greatly reduced raw emissions. Combustion chamber sensors, a world first, are one highlight. These enable the combustion processes inside the engine to be regulated even more precisely – yet another Audi innovation.
The latest TDI engine ultimately becomes the clean high-tech diesel when it is combined with the ultra low emission system. This reduces nitric oxides by up to 90 percent. This system uses the additive AdBlue, a biologically degradable water-based solution. A minute dose is injected into the system upstream of the DeNOx converter. The ultra low emission system comprises the catalytic converter and a metering module, the AdBlue tank and heated lines, and an extensive system of sensors. The additional oxidation catalytic converter and the highly efficient regulated diesel particulate filter complete the comprehensive exhaust emissions control system.
Great potential for global reduction in fuel consumption
Thanks to these minimal emissions, modern direct injection diesel engines can be used anywhere in the world, even in California, where the world's strictest emissions regime applies. Compared to the fleet average for the spark-ignition engines, the most common power system in the USA, the TDI has a consumption advantage of up to 35 percent. This means that diesel technology more than any other current power system can help to reduce the consumption of fossil fuels.
The latest TDI with ultra low emission system confirms Audi's pioneering role in implementing low-consumption technologies. When Audi put the first TDI into series production in 1989, it was a remarkable milestone in technical progress. TDI rapidly developed into a synonym for supreme pulling power and maximum efficiency, and it thus became a trendsetter for the entire automotive industry. Until today, no other drive system has managed to beat the turbocharged direct injection diesel for agility and low fuel consumption figures under real-life operating conditions.
Extensive package for reducing CO2 emissions
For Audi, perfecting the TDI is part of the integrated technology strategy for further reducing CO2 and other emissions in all its models. All in all, Audi is relying on the great potential of its modern combustion engines. With direct injection and turbocharging, plus high torque with reduced cylinder capacity and lower losses due to friction, the TFSI spark-ignition engines, like the TDI diesel engines, have the best consumption figures available today.
The latest generation hybrid module
For specific requirements in certain markets, it makes sense to complement the combustion engine with a hybrid module. At the IAA, Audi is presenting a drive train model with the latest generation of its hybrid drive concept. Because of its straightforward, modular structure, it can be fitted to any Audi model with a longitudinally installed engine, and it can be combined with almost any combustion engine. Audi will put its hybrid concept into series production as soon as this provides decisive benefits for the customer. Of course Audi sets very high standards for the quality of the hybrid drive – it must rival the efficiency of the latest Audi TDI technology.
The Audi hybrid module is configured as a single-shaft parallel hybrid. Here, the electric motor/generator is integrated into the drive train between the engine and gearbox. As a so-called full hybrid, this system can run on either the spark-ignition engine or the electric motor, or combine the power of the two. When it is coasting or braking, kinetic energy is converted to electrical energy, fed back into the battery and converted to forward propulsion as necessary.
Parallel hybrid is most efficient solution
The principle chosen by Audi is that of parallel hybrid – a new solution in this class that has a potential superior to the competition. It is more efficient than any other system currently on the market, especially when driving long distances and on motorways. In addition, its spontaneous response makes sporty-dynamic driving possible. This allows us to retain Audi's typical handling characteristics, even with a hybrid drive.
An important basic factor for the high efficiency of the hybrid drive is an extremely efficient combustion engine. The Audi 2.0 TFSI is characterised not only by its very high 155 kW / 210 bhp of output and its peak torque of more than 300 Nm, but also by its very low fuel consumption. Its opposite number on the electrical side also represents an optimum of efficiency and power density. The electric motor, a permanently excited synchronous motor, develops a further 32 kW / 44 bhp of output and it peak torque of 230 Nm practically from standstill.
Eight-speed tiptronic with electric motor
The electric motor is integrated in the housing of the eight-speed tiptronic gearbox, which is also new. The complete unit does not need any additional installation space. Space has been created by doing away with the hydraulic torque converter. A dual-mass flywheel absorbs vibrations from the Audi hybrid module, while a wet multi-plate clutch takes care of coupling and decoupling the combustion engine and the electric motor.
A large portion of the high-tech competence of the Audi hybrid module can be found in the precise control of this clutch. The combustion engine is started and stopped extremely quickly and quietly, so that is can hardly be noticed by the passengers. The hybrid drive is configured for purely electric driving at speeds up to about 50 km/h and a range of about three kilometres. That is ample for a large proportion of inner-city driving.
Especially compact battery guarantees usability
The energy for this comes from a lithium-ion battery of the latest design. Compared to the nickel metal hydride technology currently in use, the size and weight of this system is reduced by about a half with a comparable performance.
Its operating voltage of 264 volts comes from a battery pack that is just 26 litres in size. Its maximum output is 39 kilowatts. The Audi hybrid module allows the volume of the luggage compartment and its usability to be maintained without restriction.
Innovative brake system for optimised energy regeneration
The electric motor regenerates a major part of the battery charge when the vehicle is braked – so-called recuperation. A completely new brake system enables hydraulic and electrical braking power to be variably mixed. With this system, electrical braking power is optimally tuned to the charge state of the battery, up to a maximum of 30 kW, and the rate of energy regeneration is increased significantly compared to previous systems. The feeling at the pedal and the braking distance are not affected by this.
Just 100 kilograms additional weight
For this, the latest generation of hybrid module, the engineers have optimised every component with regard to function, size and weight. The power steering is powered by an electrohydraulic pump. Similarly, the air conditioning compressor and the vacuum pump for the brake booster are electrically driven.
The ABS and ESP driving stabilisation systems have been extended in their functions and have fully integrated the electric drive components in their control regime. The additional weight caused by the hybrid is now a mere 100 kilograms.
Just 6.4 litres standard fuel consumption
The combination of 2.0 TFSI engine and hybrid module presented at the IAA achieves all the driving performance of a high-displacement, naturally-aspirated six-cylinder engine. In particular its extremely spontaneous and powerful pulling away characteristics guarantee the dynamism that is typical of Audi. This pioneering combination has a fuel consumption that is about 30 percent lower that a conventional spark-ignition engine. With a vehicle weight of 1,850 kilograms – corresponding to a luxury class saloon or a medium size SUV – its fuel consumption in the standard cycle is just 6.4 litres per 100 kilometres.
A clear course into the future
With its integrated efficiency strategy, Audi is systematically working on achieving further reductions in fleet fuel consumption. The combustion engine will remain the major drive system for the foreseeable future. Already an extremely efficient principle, the TDI still has considerable potential for further reductions in fuel consumption, and the ultra low emission system is the guarantee that it remains absolutely future-proof. The TFSI principle and the Modular Efficiency programme will guarantee significantly reduced CO2 emissions for all new model series. Finally, TFSI engines, complemented by hybrid modules, could represent an alternative to the TDI in certain markets.
And one thing is indisputable for Audi. Efficiency and reduced fuel consumption will never be achieved at the expense of the brand's other strengths. Audi will retain and bolster its sporty-elegant character, drivability and the high quality standards of its models, even as emissions are further reduced.

Frankfurt: Audi’s New A4 Holds Widespread Appeal


Despite not coming off like a showstopper, the new-for-2008 A4 models on Audi's stand were mobbed, even a day after their introduction. Competing engineers and hordes of journalists were seen crawling over, under, and in Audi's entry-level sedan, with many of them measuring and taking stock of the Four Ring's new offering. We even watched an extremely tall man (perhaps 7' 6") fold himself into the A4 (see above), taking advantage of the extra legroom the new model affords. With his seat all the way back, he still had his knees up and around nine-and-three on the steering wheel, but the good-natured evaluator remarked that it was normal for him to drive in this fashion, and in fact, the car was markedly more accommodating than before. We'd probably recommend our new friend stick with an A8L, however.

While the A4's styling is clearly an evolution of the previous car, with a few A5 styling clues thrown in for good measure, the design just plain works, and it looks attractive inside-and-out. The LED string headlamps really mark out the corners with authority, and the thinner, longer A5-esque taillights look at home as well. Job done, we'd say.

Of course, the proof will be in the driving, but we're excited to see what Audi's new rear-biased Quattro system does for the A4's driving dynamics. Stay tuned.

Audi Failed Again To Beat LM P2 Car

The exciting American Le Mans Series made its most recent stop at the Mosport International Raceway in Canada last weekend for the ninth race of the season. The most notable story before the race is Audi's aim to break the winning streak of Le Mans Prototype 2 cars. Although Audi competes in the Le Mans Prototype 1 class, the team is looking to beat the faster LM P2 cars which have been the overall winners for six consecutive events going into the 2007 Grand Prix of Mosport. Unfortunately for the Audi team fielding a diesel race car, they failed to take the overall victory due to a mechanical problem late in the race.

Although the pair of Alan McNish and Rinaldo "Dindo" Capello failed to take the overall win at the race, they still managed to top all competitors in their class. The drivers posted their seventh win of the season and clinched the championship for their team with three races still remaining in the season. That means that they can now focus better in beating the lighter LM P2 cars.

McNish has this to say after the race: "My Audi R10 TDI was fast and strong while excellent team strategy had put us in control of the race. But with only a few minutes to go, I encountered a technical issue with the gearshift. I was stuck in fourth gear at times losing a lot of time. I lost the lead with five minutes remaining."

"Despite Dindo and I claiming our seventh class win of the season and extending our championship lead, we're obviously very disappointed having come so close to winning the race outright," McNish added. Capello succeeded in taking a pole position for the race and with 15 minutes remaining and with McNish on behind the wheel of the Audi R10 TDI, their lead over their nearest rival is 29 seconds. That was before the problem with the gearbox occurred.

The pair now is looking to perform well at the upcoming race, the Belle Isle Detroit Grand Prix. Going into that race though, McNish admitted that the track will be difficult for their LM P1 cars developed by Audi, the same manufacturer of auto parts and accessories such as Audi floor mats. "Having just raced on one of the fastest tracks in the series at Mosport, we now head for what is likely to be one of the slowest," said McNish. "I visited Detroit last month and saw that it's a pretty slow, tight and flat concrete-lined track – exactly the opposite to Mosport."

"While I think it'll be an exciting race for what is expected to be a big crowd, I think it's going to prove extremely difficult for our Audi like most of the other 'street' tracks," the driver continued.

With seven straight victories for LM P2 cars over the more powerful but heftier LM P1 cars, it would be somewhat of an upset if an Audi R10 or any LM P1 car can beat the faster LM P2 cars at the next race.

Spied: Audi A4 Avant




With Audi unveiling its all-new A4 Sedan and RS6 Sedan and Avant this week in Frankfurt, it's easy to let lesser models fly under the radar. Lucky for us, our spy photographers never let anything slip by. They captured the first images of the A4 Avant out for testing in Germany.

While it won't share the Audi display with the A4 Sedan this week, the Avant is expect to be available in the summer of 2008. Based on the Sedan's platform, the Avant will carry over much of the sedan's styling, including a sloping roofline. Engine choices are expected to mirror those offered in the sedan with front and all-wheel drive configurations available.

Audi to launch Q7 hybrid and diesel this year


Audi of America is planning on launching its first diesel and hybrid models this year with the Audi Q7 SUV. While Audi has not said which other vehicles will get the parallel hybrid system, which can run in gasoline, an electric motor or both at the same time, several other Audi hybrids are expected to follow the Q7.

The company has been working with parent Volkswagen and Porsche on the development of hybrids, and will be the first to hit the market with a hybrid between the three auto makers. Porsche will follow with a hybrid Cayenne SUV by 2010.

Audi technicians say that the hybrid system can easily be adapted to different model ranges and easily integrates with existing drivetrains.

The Audi Q7 will be powered by a 3.6-liter that produces 280 horsepower and is mated to an electric engine. The hybrid system will use about 23 percent less fuel. Audi says it cannot provide a mileage range as of yet. The electric motor works at speeds of 12 to 15 mph without gasoline, and will go as fast as 31 mph.

If the Audi Q7 hybrid is cruising and the driver takes his foot off of the accelerator, the system turns off the gasoline engine and continues to move at speeds as high as 75 mph. Other features include an AC system, automatic transmission and brake booster that all run off the electric motor. When the driver steps on the brakes, the 152 pound battery begins charging.

The Audi Q7 diesel variant will be powered by a 3.0 liter V6 turbodiesel engine producing about 230 hp and about 400 pounds-feet of torque. It will be available for all 50 states at the end of 2008. The diesel Audi Q7 is expected to have 600-mile range on one tank of gasoline.

Audi is also said to be working on an ethanol version of the A5 coupe for Europe. There is no decision if it will be offered in the U.S.

Performance Audi TT Coupe & Roadster?



Reports from Europe suggest Audi is working on a high-performance version of their ever popular Audi TT. Although the current range includes a 3.2-litre V6 Quattro All-Wheel-Drive variant (using the same engine as the last generation Golf R32), Audi is hoping for more with the new killer TT (to be named TT-R).

As for the all important powerplant question, the cat is still in the bag, originally many believed the car would be powered by a twin-turbo version of the current 3.2-litre V6, but in recent days, credible sources have informed the automotive world that Audi is planning a new five-cylinder turbo unit, possibly a 2.3-litre turbo engine, and not just for the TT, but for other models as well.

Power is expected at around 230kW (no word on torque). Although there are no images of the new beast, we expect the usual power enhancement features, such as lowered suspension, more agressive body kit and beefed out wheel arches.

New Audi A4 Officially Revealed In Detail



















After yesterday's A4 image leak, the official press kit has been made available. As one of the most widely anticipated debuts for the Frankfurt Motor Show in two weeks time, the A4 is Audi's bread and butter model. Therefore, the pressure for Audi to fix the short comings of the previous generation was ever looming and judging by this initial information, its seems they have succeeded.

The new A4 gets many new electronic and assistance features found in larger BMW and Mercedes models. Features such as adaptive shock absorbers, seat fans, adaptive airbags/belts, adaptive cruise control, radio-operated key, variable steering as well as other Audi features found only in A6 and A8 models which include MMI and a 10-channel 505-Watt Bang & Olufson 14 speaker stereo system. Lastly, for an added touch of the Audi R8, the xenon plus headlight option includes 14 white LEDs as day-time driving lights.

A new driver assistance feature known as Audi Drive Select provides two sport settings for the adaptive suspension. In addition, four other pre-configured modes include comfort, auto, dynamic or individual (only available with MMI option) settings. Drive Select influences accelerator pedal response, tiptronic shift points, power steering assistance, steering ratio and electronically adjustable shock absorbers. For safety, Audi's new Lane Assist uses a camera in the windshield to monitor lane position above 65 km/h and alerts the driver by vibrating the steering wheel when a lane changes occurs without using the turn signal. Audi also has Side Assist which uses radar sensors in the front and rear bumpers. The system warns the driver of vehicles in blind spots or fast approaching from behind. The driver is warned by a flashing LED on the outside housing of the side view mirror.

One of the biggest challenges Audi faced in the development of this successor was driving dynamics. With an engine position which sat just forward of the front axel of the previous generation, equilibrium was adversely affected resulting in an understeer problem. Compared to its German rivals which are rear-wheel-drive biased, Audi was at a disadvantage. However, with this all-new MLP platform the front axel gets moved forward by 154mm for a much improved axel-weight distribution. Also aiding weight distribution, Audi has moved the transmission differential forward just behind the engine but in front of the clutch or torque converter.

The new A4 has grown to 4.7 meters with sportier proportions, the front overhang is shortened while the bonnet and wheelbase (which it shares with the new A5) are longer. As a result, the interior grows by 20mm which results in rear passenger knee room increasing by 36 mm to a luxurious 908mm and the boot can now hold 480 liters (which doubles with the rear seats down) no matter if the car is equipped with quattro or not.

The A4 will be available in the familiar four trim packages: Attraction, Ambition, Ambiente and S-Line. One of the more interesting features of the cockpit, reminiscent of BMW's E46 3 Series, is the center console which is oriented towards the driver by 8 degrees.

Despite the bigger size of the body, the new A4 body shell weighs an amazing 10% less than its predecessor. Audi has accomplished this through the use of new high-strength steel grades. Aerodynamics also improve to 0.27 drag coefficient, which is 3 to 5% lower (depending on model) although the frontal area is slightly wider.

Five engines will be made available, namely in the petrol range, the 1.8 liter TFSI producing 118 kW (160 bhp) and 250 Nm torque while the 3.2 liter FSI produces 195 kW (265 bhp) and 330 Nm torque. For the diesel engines the 3.0 liter TDI V6 makes 176 kW (240 bhp) and 500 Nm torque. The 2.7 liter TDI V6 puts out 140 kW (190 bhp) and 400 Nm torque. Lastly, the highest volume diesel, the 2.0 liter TDI makes 105 kW (143 bhp) and 320 Nm torque.

0-100 km/h (62 mph) performance at a glance:

1.8L TFSI = 8.6 sec

3.2L FSI = 6.2 sec

2.0L TDI = 9.4 sec
2.7L TDI = 7.7 sec

3.0L TDI = 6.1 sec

The engines can be combined with a six-speed manual, tiptronic automatic or the multitronic continuously variable transmission with either front wheel drive or quattro permanent all-wheel drive system. Available as an option, tiptronic transmissions get steering wheel mounted shift paddles.
The new Audi A4 will be available this November with a base price in Germany approximately EUR 26,000.

Press Release
In its design, the new A4 reveals its sporty, progressive character: taut and dynamic in its outlines, it speaks the language of technical perfection. With an overall length of 4.70 metres, the saloon has a substantial, powerful road stance and offers its occupants ample space in an interior full of light. The workmanship is typical of an Audi – quality with no compromises. The controls can be backed by the extra refinement of innovative assistance and multimedia systems. In the safety area, the brand with the four-ring emblem sets new standards: the coordinated action of the airbags and front seat belt force limiters protects the occupants even more effectively.

When compared with the previous model, the A4 has new, sporty proportions. The front body overhang has been drastically shortened; the bonnet and wheelbase are both longer than before. In the driveline, the differential has changed places with the clutch (or torque converter), making it possible to move the front axle forward by 154 millimetres. This innovative solution ensures ideal axle-load distribution. The new A4 is the sportiest saloon in the midsize car category: agile, light and precise to control. Its dynamic suspension is a totally new design, with most of its components made from weight-saving aluminium.
The results are impressive: supremely dynamic road behaviour and effortlessly precise handling.

New high-tech options make the A4 driving experience even more fascinating: Audi drive select varies the engine, automatic transmission, steering and suspension damping characteristics to suit the driver's preferences at any given moment. Audi dynamic steering varies its ratio according to the car's speed and keeps the new A4 stable close to the handling limits by slight, almost instantaneous changes to the steering angle. The damping control system for the hydraulic shock absorbers varies the damping characteristic individually, to combine sporty driving enjoyment with maximum road safety.

The new Audi A4 is being introduced with a choice of five engines, their power outputs ranging from 105 kW (143 bhp) to 195 kW (265 bhp). The four-cylinder petrol engine, like the diesels, is turbocharged, and both types of engine have direct fuel injection. All the engines, with their supremely refined flow of power, make the A4 a pleasure to drive and, thanks to their high efficiency, consume distinctly less fuel than the previous versions.

Various transmissions are available: a six-speed manual gearbox, the tiptronic automatic transmission, the multitronic continuously variable transmission, and either front-wheel drive or quattro permanent all-wheel drive, which has been subjected to intensive development work that has made its performance even more dynamic.
Body and interior

There is ample space for the occupants and their luggage in the light, generously sized interior of the new Audi A4, with its clear layout and attractive styling. Thanks to new high-tech materials and processes, the bodyshell is even safer and more rigid than the previous model, although it weighs significantly less. With a drag coefficient of cD = 0.27, the new Audi A4 has the wind-cheating outlines that make for quiet, efficient travel.

Inside the new A4 there is a sense of light and space that would do justice to a car in a much larger category. The saloon's 2808-millimetre wheelbase is not only more generous than its core competitors but also distinctly longer than the previous model. The interior is now 20 mm longer and rear-passenger knee room has gone up by a remarkable 36 mm to 908 mm. Headroom and width at shoulder height have also been increased. Every passenger in the new A4 has access to convenient features such as large cup holders and softly upholstered armrests.

To sit in the new A4 is to feel comfortable and content from the very first moment on – a typical 'Audi effect'. The interior seems to fit the occupants like a well-made sports jacket. Its graphic design, featuring taut surfaces and dynamic lines, conveys precisely the sense of lightness and athletic vitality that is inherent in every aspect of the new Audi A4. The choice of materials, how they are used and how satisfying they feel are factors that delight the senses of those who ride in this new car.

Every element reveals the careful attention to detail and the already proverbial striving for top quality that are associated with Audi as a premium brand. The switches, for instance, operate with precisely defined effort and no excess movement; the rotary controls click smoothly into place at each setting. This is the sound of true technical perfection. An optional-extra lighting package adds still more lustre to the interior.

The front seats are designed to integrate the driver and passenger perfectly into the sporty ambience. Their height can be varied, and they support and locate the occupant's body ideally. The driver's hand instinctively finds the gear lever where it is expected; the position and angle of the steering wheel and pedals seem to have been chosen to suit the driver's very own preferences. The steering wheel can be adjusted by 60 mm in reach and 50 mm in height.

As an alternative to manual seat adjustment, Audi can supply electric seat adjustment as an extra, with a position memory function as an additional option. Another optional extra is seat cushion and seat back heating. If the sports seats are chosen, the seat base angle is adjustable, the seat cushion can be extended and electric four-way lumbar support is a standard feature.

The new 'Climatic Comfort' seats bring a touch of true large-car luxury to the Audi A4. They are upholstered in perforated leather and have small fans with six speed settings to ventilate the seat cushion and seat back. To avoid the risk of excessive cooling, a heating function cuts in automatically.

The 'Comfort' seats are available in a specially perforated version of the Milano leather upholstery, in a choice of four colours. For the standard and sports seats a second type of leather (Valcona) is available, and the sports seats can be obtained with combined Alcantara and leather upholstery.
Sporty elegance: colours and materials

In every area of its colours and materials, the new Audi A4 pursues a sporty, elegant approach. In addition to the standard decor inlays, an aluminium version and three types of wood that can also be combined with a special aluminium look are available. The sporty S line has a black interior including the roof lining.

The boot now holds 480 litres whether the car has front-wheel drive or quattro permanent all-wheel drive. This volume is larger than any direct competitor can offer. The loading height is only 673 millimetres, and together with the flat floor and straight side panels makes the boot extremely practical in use.

For larger loads, for instance after major shopping trips, the rear seat back can be folded down in two sections, thus increasing the load volume to a maximum of 962 litres. A load-through facility with detachable ski sack can be ordered as an optional extra.

On every new A4, the boot lid can be released in three convenient ways: by radio signal from the remote control, with a pushbutton on the driver's door or with the electric soft-touch release in the boot lid handle recess. The lid then swings up automatically on its new hoop-pattern hinges; only slight effort is needed to close it.
Weight-saving steel construction – the body

The technical features of the steel bodyshell are also evidence of the major steps forward that have been taken on the new Audi A4. The body is extremely light in weight: although almost twelve centimetres longer and over five centimetres wider than its predecessor, the bare bodyshell weighs about ten percent less – an excellent starting point for a saloon car of low gross weight. The Audi A4 1.8 TFSI, for instance, tips the scales at only 1,410 kilograms.

This weight saving is due to specific use of new grades of steel that combine exceptional strength with low weight. Only these ultra-high-strength steel grades give the body the high level of rigidity needed for precise, sporty handling and excellent ride comfort.

Audi is the first automobile manufacturer to produce these 'tailored blanks', as they are called, from ultra-high-strength steel in its own factory. They account for 12 percent of the weight of the new A4's bare bodyshell without doors, lids and windows. 18 percent are accounted for by ultra-high-strength steel grades, 32 percent by high-strength steels and 38 percent by conventional deep-drawing grades of steel.

The complex body structure is designed to suppress vibration to the maximum possible extent. Areas at the front end of the car that could be subjected to severe sources of potential vibration as the car is driven have been specifically reinforced, and the larger cavities in the body, including posts and sills, have been divided up into smaller volumes by means of bulkheads.

The occupants are protected as far as possible from the effects of collisions of all kinds by carefully matched body elements. For its occupant protection concept, Audi makes use of a number of sources including the large database that it has compiled itself: the Audi Accident Research Unit (AARU) investigates and analyses accidents all over the world. One of its findings is for instance that persons of smaller stature are still exposed to greater risk of injury in a frontal crash than others.

For this reason, Audi has coordinated the network of occupant restraint systems more closely than has ever been the case in a midsize car. Sensors on the seat rails determine the actual position of the seats. This data is supplied to the control unit that regulates the action of the adaptive seat belt force limiters and airbags. In this way the distance available for the belt and airbag to restrain the upper part of the seat occupant's body can be used as effectively as possible.
For every eventuality – six airbags as standard equipment

Six airbags are installed in the new Audi A4 as standard, with two more as an optional extra for the outer rear seats if required. Isofix child seat mountings at the rear are another optional extra, and are also available for the front passenger seat, in which case its airbag is de-activated. The front seats and head restraints are designed to support their occupants safely if the car is involved in a rear-end collision.

The new A4 is one of the first cars to comply with all the new legal requirements in Japan and Europe regarding a collision with a pedestrian. It is also well equipped to withstand minor impacts with solid objects or other vehicles at speeds up to 15 km/h without damage to the main body structure.

The new Audi A4 cleaves the air ahead of it smoothly and quietly, like a large luxury car, thanks to careful attention to detail design in the aero-acoustic wind tunnel. The drag coefficient (cD) of the basic version is only 0.27. Depending on which engine is chosen, the overall aerodynamic drag is between three and five percent lower than the equivalent preceding models, although the frontal area of the new, wider body has gone up from 2.14 to 2.19 square metres. Good airflow around the body is aided by an almost complete undertray.
Design

The new Audi A4 has many fascinating sides to its character, all of them expressed by the outlines of its body. Their high-tech precision clearly demonstrates the leading position that Audi occupies in automobile design.

The new A4 has a spacious saloon body and a firm, muscular stance on the road. Its length (4703 millimetres) and width (1826 millimetres) exceed those of its core competitors, and sporty dynamics were the guiding principle in its development.

The proportions have a new balance compared with the previous model: the front body overhang has been considerably reduced and the bonnet and wheelbase are now noticeably longer. A long, coupe-style roof line emphasises the flowing silhouette. The roof meets the side sections of the body at an almost invisible zero-gap joint – just one of the many details that uphold the Audi principle of high technical precision.
Dynamic balance – interplay of body lines

The completely new outer body panels of the A4 consist of sculptured, curving surfaces framed by sharply defined outlines. The 'dynamic line' above the door sills rises slightly to the rear, the 'tornado line' below the windows slopes down. In this way the two contours add profile and dynamic balance to the sides of the car. Large wheels and boldly styled wheel arches emphasise this impression of concentrated energy.

The new A4 is a car that presents a confident personality to the outside world – an impression borne out by the broad, low, sporty 'single-frame' radiator grille.

The optional-extra xenon headlights are technical works of art, with powerful visual accents set by their electrodeposited chrome 'wings' and the standard daytime driving lights. Depending on the lighting technology used, their design differs: in the xenon plus headlights, the daytime driving lights each consist of 14 white light-emitting diodes.

The rear end of the body, which tapers strongly inwards, interprets the car's sportiness in a most convincing way. The slim, tapered-off light units create a visual relationship with the road. The exhaust tailpipes are straight – even on diesel-engined cars a hint at the powerful character of the TDI engines. A4 models with the sporty S line exterior package differ in certain details, for instance the front air dam. The new Audi A4 can be supplied in 15 body colours – a wider choice than that offered by any of its competitors.
Controls

Optimal car control is one of the major areas of competence in which Audi leads the way. The new A4 is convincing in its ergonomics, which are logical in every detail and permit the controls to be operated intuitively.

The cockpit in the new Audi A4 is clearly oriented toward the driver. The centre console is inclined at 8 degrees to the driver's side of the car and forms a single visual unit with the instrument panel.

A multifunctional leather-covered sports steering wheel with three spokes is available as an optional extra. It has small drum-type and pushbutton controls for the basic functions of the navigation and audio systems, the car phone and the voice control system. For the A4 with automatic transmission, shift paddles behind the steering wheel rim are another optional extra.

In many aspects of its detail design, Audi's new midsize saloon pursues the same approach taken on the A8, its larger sister-model in the luxury segment. The Driver Information System (DIS) display located between the speedometer and revolution counter dials is a standard item on cars with a V6 engine.

A 6.5-inch black-and-white display screen is located on the upper part of the centre console, where it can also be clearly seen. It supplies information on the audio and air conditioning systems and the settings possible when the CAR menu is selected. These settings enable customers to configure many of the car's functions themselves. The large switches and pushbuttons on the standard audio systems with MMI control logic are ideally positioned for easy operation, between the automatic air conditioning and the ventilation outlets.

When the new Audi A4 is ordered with a navigation system, the Multi Media Interface (MMI) is integrated into the centre tunnel. MMI has been highly praised by testers on many occasions and has proved to be superior to systems offered by competitors. 15 large switches and a volume control are grouped around a central turn-and-press knob, and used to select the navigation, information, CAR menu, set-up, telephone, address book, CD/TV and radio functions effortlessly, intuitively and logically. If the car has the high-end navigation system with DVD drive, all the relevant information appears on a colour screen measuring 7 inches from corner to corner.
Driving off safely and smoothly: the electro-mechanical parking brake

Another control on the centre tunnel operates the electro-mechanical parking brake, a convenient luxury feature also derived from the Audi A8. It assists the driver when the car is moving away from a standstill, and also functions as an emergency brake. The optional-extra Audi hold assist adds extra functions. The space formerly occupied by the handbrake lever can be used for additional convenience: as an optional extra, a centre armrest with extra-soft upholstery can be installed, with two 12-Volt power sockets beneath it.

The new radio-operated key for the Audi A4 has no conventional blade: to start the engine, the key is simply pressed into the ignition switch. It can memorise several of the car's specific settings and also store servicing information and fault messages. The 'advanced key' high-end version means that the key does not even have to be taken out of the driver's pocket. In this case sensors are used to lock and unlock the car and the engine is started and stopped by means of an elegantly designed pushbutton on the centre tunnel.

Audi supplies various stages in headlight technology. In the top version, the xenon plus headlights can be combined with 'adaptive light', which directs the headlight beams in the appropriate direction as the car turns a corner.

The new A4 is supplied with automatic air conditioning as standard equipment; the system is an entirely new, more efficient development that has enabled cooling performance to be increased by 10 percent and at the same time the fuel consumed to operate the air conditioning has been reduced by 20 percent. As an optional extra, a version with three temperature zones can be ordered; it permits separate control of temperature and airflow for the driver, front passenger and rear passengers.

Running gear

The new A4's dynamic suspension combines sporty precision with high stability and supremely confident road behaviour. It is a totally new design, with many components made from aluminium in order to reduce unsprung weight. Two technological breakthroughs make the driving experience even more fascinating: adaptive shock absorber control and Audi dynamic steering.

The Audi dynamic steering system alters its effective ratio according to road speed, and helps to keep the new A4 stable when the handling limits are approached by making slight but extremely rapid steering corrections. The adaptive shock absorber control maintains optimal tyre contact with the road, for safety allied to dynamism in just about every situation, and so that even the enthusiastic driver can be sure that maximum safety is always available.

Interchanging the differential and the clutch has enabled the front axle to be moved forward by 154 millimetres. This change, aided by moving the car's battery to the boot, helps to achieve ideal weight distribution.

With its wide track –1564 mm at the front, 1551 mm at the rear – the A4 suggests its dynamic power even at a standstill. To drive it is to experience the sportiest car in the midsize category: agile, effortless to handle and safe at all times. With its almost neutral steering response, the new A4 can be cornered at high speeds.

Strong structural members – rapid build-up of forces

The front axle pivot bearings and the five links that locate each front wheel are made of aluminium. At the front of the A4, the engine and suspension support beam is also made of aluminium, and bolted rigidly to the body.

The steering gear is located low down and well forward, with the track rod transmitting steering movements directly to the wheels. Rack and pinion steering provides well-defined, sensitive feedback from the road but transmits in effect no undesirable jolts or shake. The steering ratio of 16.1:1 is sporty and direct, but never nervous in its response. The controlled-output pump only delivers the amount of power steering oil actually needed; this lowers fuel consumption by about 0.1 l/100 km. Cars with V6 engines are equipped as standard with power steering that varies the degree of assistance according to road speed.

The development engineers based the design of the rear suspension on the controlled toe-angle principle with trapezoidal links used for the larger A6 and A8 model lines; this is a space-saving layout that combines sporty handling with a high level of ride comfort.

Applying the lightweight construction principle, the steel axle beam is attached to the body by four rubber bushings; these are very rigid laterally to ensure dynamic handling, but softer longitudinally for greater vertical and lengthwise compliance. The trapezoidal links, wheel carriers, upper wishbones and track rods are all made of aluminium. The well-proven solution comprising separate spring and shock absorber mountings, and in particular the new spring connection points at the wheel carriers, ensure good initial suspension response.

Versions of the new A4 with engine outputs up to 118 kW (160 bhp) run on pressed-steel wheels with full-size wheel covers and 205/60 R16 tyres. Cars with more powerful engines have elegant alloy wheels and 225/55 R16 tyres. Optional extras are also available from quattro GmbH: 18-inch wheels with 245/40 tyres and also 19-inch wheels. 8 J x 17 wheels can be obtained with run-flat tyres. Standard equipment on cars with a V6 engine is a tyre pressure monitoring display that operates extremely accurately and reliably.

Powerful stopping too – the brake system

Behind the car's big wheels are brakes with 314 mm diameter front and 300 mm rear discs; the front discs are internally ventilated. The high-performance brake pads, a new development, now cover 20 percent more rubbed area. The front brakes on V6-engined cars are even larger, with 320 mm discs and composite spheroidal-graphite and aluminium callipers. In every version of the A4, the brake pedal has a firm, precise action, and thanks to accurate feedback the driver can control the brake application effectively without applying excessive pressure.

The latest generation of ESP stabilisation system adds to the operating refinement of the brake system. New hydraulic valves build up pressure with exceptional accuracy, and the regulating action takes place without judder. At speeds below 70 km/h, the driver can disconnect certain anti-slip functions by pressing a button briefly. The wheels can then spin, but this can be beneficial in certain circumstances, for instance when driving on snow.

ESP in the new A4 has a number of additional functions – it can for instance stabilise a trailer if it begins to snake, dry the brake discs in wet weather and activate the hazard warning flashers if a panic brake application is made.
Audi drive select – up to four different cars in one

Those who drive the A4 hard and enthusiastically can choose between two sports suspension settings, or alternatively rely on an innovative technology – the innovative system known as Audi drive select. This is available in various stages, which influence an increasing number of technical components and functions on the car: accelerator pedal response, tiptronic shift points, power steering assistance, the steering ratio and the action of the electronically adjustable shock absorbers – another new feature.

The driver can select the comfort, auto or dynamic modes at switches on the centre console. If the A4 is equipped with the MMI control system, a fourth mode, "Individual", is available; this enables an individual profile of 24 settings to be configured. Audi drive select transforms a single A4 into up to four different cars – a range of driving pleasure, dynamism and ride comfort that is unmatched in the midsize car category.
As fast as a professional rally driver –Audi dynamic steering

The new A4 features yet another pioneering technological development: Audi dynamic steering. Its key element is a superimposed gear system that alters the overall ratio according to road speed and the chosen Audi drive select setting. This concentric-shaft steering gear is extremely compact and light in weight; it has a precise action free from any slack. It was first developed for use in robots and for space travel applications; the expedition vehicles on which it was installed have already traversed the surface of the moon and Mars.

Audi dynamic steering makes the steering ratio more direct at low speeds, with a higher level of power assistance. This renders the steering extremely light when manoeuvring, and only two turns of the wheel are needed from lock to lock. As the car's speed increases, however, the steering ratio becomes gradually less direct and in parallel with this the amount of power assistance is reduced. At high motorway speeds the A4 can therefore be driven smoothly and has excellent straight-line stability.

Audi 's high-tech steering can do even more. It is closely networked with the ESP and therefore receives precise information about the car's attitude as the handling limit is approached. If the A4 threatens to oversteer, for instance after an abrupt avoidance manoeuvre, the steering performs slight corrective impulses in the direction needed to reduce this tendency. Such corrective action takes place faster than even an experienced rally driver could react. This rapid response means that brake applications are often not needed, so that the car continues its journey more smoothly and dynamically.

The system also takes action if the car understeers: it selects a more indirect steering ratio for a short time, the aim being to prevent the driver from turning the steering beyond the point at which the tyres still have plenty of road grip. With these capabilities, Audi dynamic steering represents leading-edge technology in this car market segment.

The optional-extra damping control permits individual suspension settings to be chosen. These are based on the lowered sports suspension. Continuously adjustable hydraulic shock absorbers permit the damping characteristic to be varied individually at each wheel. This means optimal contact between the tyre and the road in almost every situation, for greater safety and more dynamic road behaviour.

Equipment and trim

The new Audi A4 can be ordered ex factory with one of four equipment and trim specifications, all of them with a very full list of items. The new saloon model, however, can be further enhanced by choosing from a selection of luxury optional extras. Its innovative assistance systems and the broad range of electronic components are taken directly from the large luxury car programme.

The four equipment and trim lines have been named Attraction, Ambition, Ambiente and S line, and each of them can be ordered with any of the available engines. Even the Attraction line gives the new A4 a high level of comfort and convenience. 16-inch wheels emphasise its sporty character, and the daytime driving lights give it a striking presence on the road. Automatic boot lid opening, the electro-mechanical parking brake, the 6.5-inch black-and-white display screen and the automatic air conditioning all add to the high standard of comfort and convenience, and the 'chorus' radio with MMI control logic has a CD player and eight loudspeakers.

Ambition, the second equipment and trim line, is sporting in character. Its most obvious feature are 17-inch diameter cast aluminium wheels of six-spoke design. Sports suspension, which the customer need not specify if not required, makes the handling even more dynamic, and the three-spoke leather-covered sports steering wheel is a striking feature of the interior.

The third equipment and trim line is Ambiente, which focuses on comfort. The A4 then runs on specially designed 16-inch cast alloy wheels of seven-arm pattern. The front seats can be heated. The Audi parking system makes parking in reverse easier and cruise control maintains a constant road speed when required. Other features for extra comfort and convenience are the multifunctional leather-covered steering wheel and a front armrest with two power sockets; the lighting package adds further highlights.

Customers with a dynamic approach to driving will tend to favour the sporty S line, which offers an exterior design package and a sports package. Among its most attractive items are visual changes inside the car, extra-firm suspension settings, 18- or 19-inch alloy wheels and two exclusive colours: Misano red and Monza silver.

Multimedia in the car – a technology area of the future

Audi has a complete system of modular elements to offer in the communication and infotainment area. The first stage above the standard 'chorus' radio offers an upgrade to the 'concert' or 'symphony' systems. Both are from the new generation of audio equipment and operate in conjunction with a 6.5-inch display screen. The controls for both systems – a turn-and-push knob and large switches that can be operated intuitively – use the much-praised MMI logic principle. Both these radios include a double tuner, and the DAB digital broadcasting standard is available if required. A six-CD changer is integrated into the 'symphony' radio.

An optional extra for both systems is a lifestyle feature that looks well ahead into the future: the Audi Music Interface (AMI). It has iPod capability, with the menu structures visible on the car's display screen. Music from other players can also be listened to by way of the AMI interface.
'Wellness for the ears' from Bang & Olufsen

The next two system stages feature the MMI Basic plus or standard navigation system with DVD including MMI. In these cases, all the system's controls are moved to the MMI control terminal. MMI Basic plus has a black-and-white screen with arrow display and an integral audio CD changer.

The full version of the navigation system with DVD including MMI incorporates a double tuner and a 7-inch colour screen, with navigation information taken from a DVD drive. The high-end system can be extended to include voice control, the Audi Music Interface and a digital TV tuner.

For perfection in sound reproduction, Audi can offer two high-class audio systems. The Audi Sound System has a 180-Watt rating and ten loudspeakers. The ultimate choice, however, is the Sound System from Bang & Olufsen. Brilliant high notes, authentic detail resolution, precise sound stage reproduction and a broad, subtly differentiated frequency spectrum – this product from the Danish audio champions satisfies every demand for top precision and quality. A 505-Watt amplifier transmits its signals according to a surround algorithm developed specially by the manufacturer, permitting the full sound experience to be enjoyed at every seat in the car. This system has ten active channels with 14 loudspeakers.

Bluetooth: the perfect link to the mobile phone

The two MMI systems both allow a mobile phone to be integrated in a very elegant manner with Bluetooth. If the driver's mobile phone supports the SIM Access Profile, it only needs to be logged into the A4's system once. The car's system then performs all the available functions automatically as soon as the driver inserts the ignition key. The mobile phone can remain in the driver's pocket; the A4 phone can access all the data from the SIM card and the internal memory. The mobile phone then shuts down, so that its battery is not drained.

The Bluetooth car phone uses the car's own aerial and is operated by voice input, via the MMI or at the multifunctional steering wheel. A digital speech processor ensures the best possible hands-free quality. Output is via the Sound System, using the radio volume control.

Innovative driver assistance systems

Audi has developed a wide range of assistance systems that bring large-car luxury to the midsize category. The Audi parking system advanced uses a rearview camera to simplify parking. What the camera sees is shown on the monitor screen of the MMI control system, together with various guide lines and panels to help in positioning the car.
Staying in lane – with Audi lane assist

Audi lane assist is a lane monitoring system that operates above about 65 km/h and warns the driver if he or she departs from the chosen lane. A miniature camera on the windscreen views the road ahead and a computer identifies the lane lines. If the car moves toward a lane line without the driver having made a turn signal, Audi lane assist warns him or her by means of vibration at the steering wheel. Vibration intensity and the point at which the warning starts can be selected in three stages.

Radar looks back – Audi side assist

Audi side assist is specifically intended for situations in which the driver wishes to change lanes. Two radar sensors in the rear bumper scan the area behind and alongside the A4; their signals are evaluated by a computer. If another vehicle is moving at the same speed in a critical area or approaching fast from behind, an LED display comes on in the outside mirror housing as a warning which the driver identifies subconsciously.

If the driver operates the flashing turn indicator, the system interprets this as a sign that he or she still intends to change lanes. The light-emitting diodes then become brighter and flash for about one second at a higher frequency. This warning is extremely difficult to ignore. Audi side assist is in action above a road speed of 60 km/h.
Relaxed driving in dense traffic – adaptive cruise control

Another assistance system that has initially been available only on luxury cars is radar-assisted adaptive cruise control (ACC). It normally maintains any preselected speed between 30 and 230 km/h, but can vary it by taking the distance from the vehicle ahead into account. The radar signals scan an area 180 metres long and cover an angle of eight degrees. The computer analyses them to determine whether and to what extent the distance from the vehicle ahead is changing.

The A4 driver selects the desired speed and chooses one of the programmes that determine the time gap from the vehicle ahead and the regulating dynamic. The system keeps the vehicle at the necessary speed by accelerating or braking as the need arises, but with the occupants' comfort also taken into consideration. The rate of retardation when braking is not allowed to exceed 3 m/s2 at 50 km/h or higher.

In certain situations, for instance if the driver ahead brakes sharply and suddenly, this automatic speed reduction may be insufficient. In such cases Audi braking guard, one of the functions included in the ACC, takes over. It calculates whether sufficient time remains available to steer round the obstacle ahead, and allows the driver a few moments to take the necessary action. If the driver does not react, he or she is called upon by an audible warning signal and red flashing lights to apply the brakes.

If the driver still does not react correctly, the Audi braking guard brakes the car sharply for a brief moment. This lasts no more than 0.3 of a second and causes the speed of the A4 to drop by a maximum of 5 km/h. This abrupt braking action 'rouses' the driver. If he or she now makes an emergency brake application, the brake assistant will support it by ensuring that full braking pressure is immediately available.
