It really is a shame that Audi has pulled out of the American and European Le Mans Series, choosing only to run its new R15 TDI Le Mans Prototype racer at this year's 12 Hours of Sebring in March and 24 Hours of Le Mans in June. All that money, effort and time to develop a replacement for one of the winningest cars in all of motorsports seems like a waste on just two races, even if they are the sport's biggest.

This image released by Audi shows the design of the new R15 TDI ahead of its track debut in March. The new diesel-powered prototype car is much more radical compared to the R10 that it replaces than that car was to the R8. The most noteworthy difference is a new front end with an elevated nose that features two supports extending down to the pavement-scraping front chin spoiler. There's clearly some F1 influence up front, though Audi opted not to switch to a closed cockpit design like Peugeot uses for its 908 HDi.

The new R15 TDI will makes its race debut on March 21 at the 12 Hours of Sebring where its predecessors, the R10 and R8, have won eight times. Two cars will be campaigned using the same driver teams as last year: defending Le Mans winners Dindo Capello (Italy), Tom Kristensen (Denmark) and Allan McNish (Scotland) in one car and Lucas Luhr, Mike Rockenfeller and Marco Werner in the second. With Acura now competing against Audi in the LMP1 class and Aston Martin joining the fray in June at the 24 Hours of Le Mans, we reiterate our sentiment that it's a damn shame the R15 TDI will only be campaigned twice.

PRESS RELEASE

Two new Audi R15 TDI at Sebring opener
- Race debut of new diesel sports car on 21 March
- 12-hour race in Florida is stern test for Le Mans
- Audi Sport Team Joest with proven driver teams

INGOLSTADT, Germany, Feb 10, 2009 - The eagerly awaited first race of the new diesel sports car from AUDI AG draws ever closer: Audi Sport Team Joest contests the notorious 12-hour race at Sebring, Florida on 21 March with two Audi R15 TDI. The US endurance classic will act as stern test and dress rehearsal for the 24 Hours of Le Mans on 13 /14 June 2009.

The new Audi R15 TDI is packed with numerous technically innovative detail solutions and differs significantly from its predecessor model the R10 TDI which was undefeated at Le Mans. The first tests with the new LMP1 prototype have been successfully completed.

"So far the R15 TDI has performed as we expected," explains Head of Audi Motorsport Dr. Wolfgang Ullrich. "Now it must also prove itself in race conditions. Sebring is a particularly hard race and is therefore perfectly suited to reveal even the smallest of weaknesses."

Proven drivers sit at the wheel of the two new prototypes. One driver line-up is formed by defending Le Mans winners Dindo Capello (Italy), Tom Kristensen (Denmark) and Allan McNish (Scotland). The Germans Lucas Luhr, Mike Rockenfeller and Marco Werner take turns at the wheel of the sister R15 TDI. Audi Sport Team Joest competed last year at Sebring in this formation.

Every new Le Mans Prototype from AUDI AG celebrated its race debut at the race track in the heart of Florida. In Audi's first ever sports car race in 1999
Audi Sport Team Joest claimed a podium position first time out with the Audi R8R. A year later the Audi R8 triumphed on its debut at Sebring. On the premiere of the R10 TDI in 2006 Audi landed the first victory worldwide for a diesel powered sports car in an important endurance race.

The brand with the four rings has won the 12-hour race at Sebring, which also forms the opening race of the American Le Mans Series (ALMS), a total of eight times, the last time in 2007.

Audi releases more details on the R15 TDI

Following its annual meeting in Germany, Audi released photos and more details of its all-new R15 TDI race car. After some spy shots and one official pic of the R15 being tested in unpainted carbon fiber, we can now see the new LMP1 car in its standard Audi livery of silver and red. Audi is billing the R15 as the first second-generation diesel racing sports car and the company has focused on creating a vehicle that can consistently beat its French challenger, the Peugeot 908 HDi.

When the R10 debuted it was the first diesel-powered Le Mans Prototype and reliability was put ahead of outright speed. This time around, Audi has optimized the aerodynamics, reduced the weight and built an all-new smaller, more efficient powertrain. The 5.5-liter V12 has been supplanted by a new V10. and although Audi hasn't disclosed its displacement, the automaker admits it's more compact, has a lower mass and features new smaller and lighter particulate filters.

While the car doesn't use a hybrid KERS system, it does have a lithium ion battery for its electrical system. The advanced battery provides higher voltage with lower weight -- always a boon in a race car. The R15 will make its racing debut March 21 at the 12 Hours of Sebring.

Audi R15 TDI: first "second" generation diesel racing sports car

# Audi launches new LMP1 racing sports car
# New TDI engine and many innovative approaches
# Race debut on March 21 at Sebring (USA)


Ingolstadt – AUDI AG is the world's first automobile manufacturer to develop a "second" generation diesel racing sports car. Audi aims to underline its supremacy and consolidate its expertise in car technology once more at the legendary 24 Hours of Le Mans with the all-new Audi R15 TDI.

The 24 Hours of Le Mans is particularly suited for this: Efficient and economical cars are especially required for the French endurance classic. Lightweight construction, environmentally friendly drive concepts and well-thought out aerodynamics are the focus of attention at Le Mans just as they are during the development of production cars. For this purpose the regulations intentionally give the engineers plenty of freedom.

Audi Sport fully exploited this creative freedom and put a new LMP1 race car on the track that differs significantly from all previous Le Mans sports cars. "The R15 TDI has many detailed technical solutions never seen before on a sports prototype," explains Head of Audi Motorsport Dr. Wolfgang Ullrich. "To a certain extent we followed entirely new routes."

Highly efficient TDI engine

The heart of the R15 TDI is a newly developed V10 TDI engine producing more than 600 hp, with a maximum torque output in excess of 1,050 Newton meters and which reflects the latest version of the TDI Technology invented by Audi. The power unit is more compact and lighter than the twelve-cylinder engine used in the preceding R10 TDI model. The specific fuel consumption and associated CO2 emissions could also be reduced. Innovations in the turbo-charging and fuel injection areas simultaneously ensure improved engine response. The R15 TDI is also equipped with a new generation of even lighter diesel particle filters.

The new sports car's aerodynamics, which play a particularly important role at Le Mans, are extremely refined. Like the DTM 2008 championship winning Audi A4, the airflow around and through the car was optimized with CFD (Computational Fluid Dynamics). Included among the many innovative detail solutions which can be spotted at first glance are a rear wing suspended from the top and a high nose.

Innovative vehicle electrical system concept

The vehicle electrical system in the Le Mans sports car is entirely new: A lithium-ion battery, as found in some hybrid vehicles, is used for the first time. It is lighter than the conventional battery and supplies a higher voltage.

The headlights fitted to the R15 TDI also benefit from the higher power. At Le Mans, Audi competes for the first time with a low beam unit comprised entirely of light emitting diodes, which represents the next generation of Audi LED technology for road cars.

Innovative approaches

Numerous innovative approaches are also hidden in the chassis and suspension of the diesel sports car. Due to the aerodynamic concept the front and rear suspension have been raised. Thanks to a longer wheelbase and the optimized vehicle weight the R15 TDI is significantly more agile than its predecessor.

Audi is the only automobile manufacturer to have won the famous 24 Hours of Le Mans with a diesel car. "With the R15 TDI we have created the base to be in a position to win also in 2009," says Head of Audi Motorsport Dr. Wolfgang Ullrich.

The Audi R15 TDI celebrates its race debut in the 12-hour race in Sebring, Florida in the USA on March 21. Audi Sport Team Joest plans to field three cars at the 24 Hours of Le Mans on June 13/14.

This is Audi’s new R15 TDI Le Mans racer, with an all-new V10 diesel engine and lithium-ion battery technology.

Talk me round this new Audi R15 TDI please.

The R15 is Audi’s second diesel endurance sports racer, after the R10 TDI that first raced in 2006. It’s designed to fight Peugeot’s oil-burning 908 and Aston Martin’s petrol-powered LMP1. The Peugeot team ran Audi particularly close in 2008, and it’s a reason why the R10 only lasted for three years, while its predecessor the R8 competed for six seasons.

The old R10 had a 5.5-litre V12 diesel, but the R15 has a new 5.5-litre V10 TDI, producing in excess of 600bhp and over 775lb ft. The V10 is lighter than the V12, and boasts new turbo technology and a revised fuel-injection system to improve the engine’s responsiveness. But Audi also promises the V10 is more fuel efficient, and produces fewer CO2 emissions.

Other changes include the huge rear wing suspended from the top and the high nose, rather than the lower nose seen on the R8 and R10. And the nose features LED technology for the low beam headlight unit, which Ingolstadt claims ‘represents the next generation of Audi LED technology for road cars’.

What about this lithium-ion battery – is it a hybrid?

No, unlike Peugeot’s experimental 908 HY. Instead, the R15 uses a lithium-ion battery to replace a conventional battery, because it’s lighter and supplies a higher voltage.

Two R15s will debut at the 12-hours of Sebring on 21 March, the opening round of the American Le Mans Series (ALMS). But Audi won't compete in most of the 2009 ALMS season - instead it's concentrating on winning Le Mans with the R15, and campaigning successfully with its A4 DTM car and the new R8 GT3.

Audi's Record-Setting Endurance Car Gets Big Overhaul, Wins Sebring

It can be stated with some gumption that Audi has been untouchable in the endurance racing world over the last several years with its R10 TDI LMP1 race car. Not content to let other automakers catch up on the technology and components found in the R10 TDI, Audi has developed its second-generation diesel enduro car, which made its debut to a record-setting win at Sebring yesterday.

When the R10 went through its first several years of Le Mans-class racing almost without losing a single race, other factory sponsored racing teams struggled to keep up with the most successful LMP1 car in history, or dropped out of the running entirely at a time when pouring millions into factory race teams is beyond the budget of most of the world's automakers.

The R15 TDI ups the ante in nearly every respect, with a brand-new V10 diesel motor outputting more than 600 bhp and, as to be expected, a tire-melting 1050 Nm of torque. Speaking volumes about Audi's increased drive toward maximum efficiency in its diesel and gasoline models, the R15 TDI actually loses 2 cylinders when compared with the previous generation V12 R10 TDI, which caused maximum confusion with its nomenclature.

In addition to completely new aerodynamics and a revised driveline, the Sebring winner R15 TDI features a lithium ion battery powering its electrical systems instead of a conventional battery. The car is not a hybrid; the lithium ion battery has nothing to do with propulsion. Due to its higher power density relative to weight, it has allowed Audi Sport engineers to free up weight for other more important purposes.

The R15 TDI LMP1 car, like Audi's race program as a whole, is not simply designed to prove racing supremacy at great development cost. Many technologies introduced on the R10 LMP1 car trickled down into Audi's production car product line. Expect the same from the R15. The real hope of enthusiasts, of course, is that some version of the new V10 diesel will make its way into roadgoing Audi R8 models. Fingers crossed, folks.
