Audi plans test run at Le Castellet

Racing debut of latest specification Audi R15 TDI brought forward
Participation in 8-hour race at Le Castellet (France)
Total of three starts in 2010 Le Mans Series


Ingolstadt, February 2, 2010 – To further prepare for the 2010 24 Hours of Le Mans, Audi Sport is planning an additional racing commitment with the Audi R15 TDI that has undergone additional development. For April 11, the participation in the 8-hour race at Le Castellet in southern France is planned for testing purposes.

Originally, the diesel racing sports car that is internally designated as "R15 plus” was to make its racing debut at the 1000-kilometer race at Spa-Francorchamps. The Belgian endurance classic continues to be on Audi Sport Team Joest’s race schedule as the final dress rehearsal for Le Mans. However, to complement these plans, Audi Sport also wants to use the season opener of the 2010 Le Mans Series (LMS) on the high-speed circuit at Le Castellet to test the "R15 plus” in racing conditions.

"We’re on schedule with the additional developments we’re making on the R15 TDI and so this race should be possible,” says Head of Audi-Motorsport Dr. Wolfgang Ullrich. "Le Castellet is a race track that lends itself pretty well to testing for Le Mans, and we’ve frequently used this circuit for our Le Mans preparation. The 8-hour race distance makes the race of further interest to us.”

Purely for logistical reasons, Audi Sport Team Joest has registered for the 2010 Le Mans Series. "But this should not at all be interpreted to mean that we will be contesting all five LMS races,” said Dr. Ullrich. "At the moment, we are only planning to race at Le Castellet, Spa-Francorchamps and Silverstone.”

The 1000-kilometer race at Silverstone (Great Britain) on September 12 will mark the finale of the 2010 Le Mans Series and simultaneously kicks off the Le Mans Intercontinental Cup, which Audi Sport Team Joest will tackle with two R15 TDI cars.

Audi banks on efficiency at Le Mans

Evolution of R15 TDI diesel race sports car
In-depth testing program in the United States and Europe
TAG Heuer is new Audi partner in LMP1 project


Ingolstadt, March 15, 2010 – Audi will fight for victory in the Le Mans 24 Hours on June 12/13 with an evolution of the R15 TDI diesel race sports car. An extensive testing program with the revised LMP1 vehicle has just begun in the United States.

"From Audi’s perspective, the LMP1 is the better alternative to Formula 1 because this motorsport category features technologies and developments which are relevant to production vehicles,” explains Head of Audi Motorsport Dr. Wolfgang Ullrich. "At Le Mans, efficiency is of paramount importance – and today, more than ever before, it is a key deliverable of production vehicles as well and it is one of Audi’s special strengths.”

Therefore, efficiency was a focal point during the R15 TDI evolution project – particularly in the complex area of aerodynamics. "This year, the Le Mans regulations prescribe air restrictors with a smaller diameter and reduced supercharging pressure for diesel-powered vehicles,” says Dr. Martin Mühlmeier, Head of Technology at Audi Sport. "Due to the reduction of engine power as a result of the regulations we have tried to make the car’s aerodynamics even more efficient than before and to improve the Cd value and downforce parameters.”

A late change in regulations that was announced only in November made the work of the engineers more difficult and forced Audi to completely modify the front section of the R15 TDI. Consequently, the diesel race sports car that is internally designated as "R15 plus” now has a new, distinctive face featuring a split nose.

The entire shape of the R15 TDI’s body has been revised for maximum efficiency. The same is true for the modified cooling and fuel tank system. The V10 TDI engine has been optimized for the smaller air restrictors and reduced supercharging pressure. "Our objective was to keep power loss to a minimum despite the limitations imposed by the regulations,” explains Ulrich Baretzky, Head of Engine Technology at Audi Sport. "We managed to do that through a lot of detailed work.” The 5.5-liter power plant continues to deliver more than 440 kW.

"After Le Mans 2009, our specifications for the R15 plus listed about 20 key items,” says Dr. Martin Mühlmeier. "Efficiency and reliability were at the top of the list but we also looked at details like improved nighttime lighting of the track. We were able to meet this wish of the drivers with a new headlight concept.”

The evolution version of the Audi R15 TDI completed its roll out on the Audi test track at Neustadt (Germany) on March 3. The vehicle was subsequently flown to the United States for two weeks of in-depth testing. Before the race at Le Mans in June, Audi Sport Team Joest will complete an extensive testing program on various European race tracks and test races at the 8 Hours of Le Castellet (France) on April 11 and at the 1000-kilometer race at Spa-Francorchamps (Belgium) on May 9.

A new partner has now joined the project: the logo of the renowned watchmaker TAG Heuer will be featured on the Audi R15 TDI. Some of the brand’s fame stems from U.S. actor Steve McQueen wearing a TAG Heuer watch in the movie "Le Mans.”
