With Bosch as a partner, Audi Motorsport prepared an electric hybrid of the R18 Le Mans sport prototype This car is nearly identical to the 2WD with an electric power and deployment system on the front

During breaking a motor unit is used to power a flywheel accumulator that close to the driver. After a the rotational energy of the flywheel is to the front wheels up to a 500 kJ maximum according to the regulations.

Ingolstadt/Munich, February 29, 2012 – sport is used yet again by AG to pioneer new technology: the brand the four ring’s new Le Mans car is the world’s first LMP1 car to a highly-efficient TDI with a hybrid quattro drive also its comeback to the race track the prototype – in a entirely new form.

R18 e-tron quattro is the name of the new Le prototype that makes its debut on May 5 in the 6-hour race at (Belgium) and fights for overall at the famous 24 Hours of Le Mans on June 16/17. Audi two technologies in a fascinating way to create a new of drive, which is also being tested for future use in cars: e-tron quattro.

behind this description is the generation four-wheel drive which Audi combines the of the proven quattro drive the potential of electromobility. To this end one axle is powered conventionally, the by electric motors.

Audi has always consciously championships and categories in racing have a close relationship to and therefore have technical for the Audi customers,” explains of Audi Motorsport Dr. Wolfgang who personally drove the new Audi R18 quattro onto the stage on evening during its world in the Audi Training Center at airport – electrically and almost quattro, TFSI and TDI are three examples of how motorsport has stimulated development. A similar tendency is with the e-tron quattro: we a completely new technology on the race before it’s introduced to the production line.”

On the Audi R18 quattro kinetic energy is on the front axle during the phase. It is fed as electric into a accumulator before being under acceleration again a speed of 120 km/h. During procedure only the front is integrated. The V6 TDI power plant 375 kW (510 hp) continues to transmit its to the rear wheels.

Both complement each other to the new drive principle e-tron

Project began in February

The project e-tron quattro for started in February 2010. 18 months passed from the conceptual ideas to the first This is a relatively short for a technology that has never tested in motorsport and which doesn’t even exist in stresses Dr.

Martin Mühlmeier, of Technology at Audi Sport. The is correspondingly big.”

Audi developed the Audi R18 ultra in to the Audi R18 e-tron quattro – Audi takes a two-pronged this year in the 24 Hours of Le and in the newly created FIA World Championship (WEC) – the 2012 year Audi R18 is built and without hybrid drive. The the base of both cars is identical, which is why the additional effort is kept limited for Sport and the race team.

The TDI invented by Audi is still the efficient drive in the world,” Dr. Wolfgang Ullrich. We are convinced the TDI has even more potential. is why Audi not only supports the in motorsport as it does in production, but in also the further development of the drive.”

Innovation in transmission area

The R18 quattro’s twin brother than lives up to its model ‘R18 ultra’: it is the lightest Le prototype that Audi has ever built. To compensate for the weight of the hybrid system the of lightweight design and construction was the throughout development of the 2011 Le race winning R18 TDI. In to the many detail optimizations is also a genuine innovation in the area: a new gearbox with a composite housing was developed for the R18 – a for endurance racing.

The new R18 ultra is a evolution of last year’s Le race winning car,” Head of Audi Motorsport Dr. Ullrich. Our drivers’ impressions very positive from the moment. Without the weight R18 ultra we would have not capable of realizing the R18 e-tron which is absolutely identical the exception of the hybrid system.”

Le Mans 2012: two R18 e-tron and two R18 ultra

Audi Sport Joest will field two R18 quattro and two R18 ultra prototypes in the Le 24 Hours on June 16/17. The two cars are driven by last winning trio Marcel (CH), André Lotterer (D) and Tréluyer (F) as well as Dindo (I), Tom Kristensen (DK) and McNish (GB) who boast a of 13 Le Mans wins between New signing Loïc Duval (F) together with Timo (D) and Romain Dumas (F) in an R18 ultra as do Bonanomi (I), Oliver (GB) and Mike Rockenfeller

Audi Sport Team also contests the World round at Spa-Francorchamps (Belgium) on May 5 in the formation. At the same time the doubles as a dress rehearsal for the 24 of Le Mans. Only Mike will miss this due to a clashing date with the

After the 24 Hours of Le Mans, plans to enter an R18 e-tron and an R18 ultra in the FIA World Endurance (WEC). André Lotterer and McNish have been as the drivers so far.

At the World Championship opener at (USA) on March 17, Audi Team Joest relies on the R18 TDI from last year, are driven by Marcel Fässler/André Tréluyer, Dindo Capello/Tom McNish as well as Timo Dumas/Loïc Duval.
