First place at Le Mans 24-Hours Race for the Audi R10


· Diesel technology combines maximum performance with low consumption

· Specially adjusted Bosch common-rail system

Together with Audi, Bosch has developed the diesel-injection system for the successful Audi R10 TDI racing cars, supplying high-pressure pumps, injectors, and the engine control unit for the motor-racing common-rail system. At the world-famous long-distance race in Le Mans, France, on June 18, 2006, the two racing cars came in first and third. With this result, the two companies have notched up a further success for their motor-racing alliance: in past years, Audi won several races in Le Mans with the predecessor model, the R8, whose FSI direct injection system was also developed together with Bosch. “We are pleased that this year we were able to play our part in racing success with our innovative diesel injection equipment,” says Dr. Ulrich Dohle, president of the Bosch Diesel Systems division. “In recent years, high performance and low consumption have already helped the diesel engine to success in series-produced models. Now, the diesel has also shown what it can do on the race track.”

As development partner, Bosch supplies the specially adjusted high-pressure pumps and piezo-inline injectors for the common-rail injection system installed in the R10 TDI. Its engineers have also used the specific racing know-how of Audi Sport as the basis for developing the new electronic control unit for the car’s 12-cylinder engine. When developing the injection system, the greatest challenge was the variable control of the extremely high injection pressure. Bosch also supplies the telemetrics system that ensures an uninterrupted transmission of data from the vehicles to the pits during the race.

Bosch has pooled all its motor racing activities into one separate unit, “Bosch Motorsport.” It is part of Bosch Engineering GmbH, the Bosch subsidiary that specializes in engineering services. Motor racing services at Bosch can look back on a long tradition: as early as 1903, Bosch engineering first helped racing drivers to victory.

The Bosch Group is a leading global manufacturer of automotive and industrial technology, consumer goods, and building technology. In fiscal 2005, some 251,000 associates generated sales of 41.5 billion euros. Set up in Stuttgart in 1886 by Robert Bosch (1861-1942) as “Workshop for Precision Mechanics and Electrical Engineering,” the Bosch Group today comprises a manufacturing, sales, and after-sales service network of more than 280 subsidiaries and more than 12,000 Bosch service centers in over 140 countries.

The special ownership structure of the Bosch Group guarantees its financial independence and entrepreneurial freedom. It makes it possible for the company to undertake significant up-front investments in the safeguarding of its future, as well as to do justice to its social responsibility in a manner reflective of the spirit and will of its founder. 92 % of the shares of Robert Bosch GmbH are held by the charitable foundation Robert Bosch Stiftung. The entrepreneurial ownership functions are carried out by Robert Bosch Industrietreuhand KG.
