As development partner, Bosch supplies systems components for the common-rail injection system of the R10 TDI – components which were developed together with Audi Sport. Bosch also redesigned the electronic control unit for the system. "This victory is a fantastic achievement, and it goes without saying that we are proud that Bosch technologies played a key role in the success of the Audi R10," said Ulrich Dohle, President of the Bosch Diesel Systems Division. "Modern high-pressure injection technology has made series-produced diesel vehicles clean and economical, and agile at the same time. Now, thanks to Audi and Bosch, the diesel is showing what it can do on the race track."

The climax of the season will be the 24-hour race in Le Mans on 17-18 June, the next race in which the R10 TDI will be competing. The excellent teamwork with Audi has already paid off there in the past:. Le Mans racing cars by Audi, equipped with gasoline direct injection developed together with Bosch, raced to victory in 2005, 2004, 2002 and 2001, while the 2003 race was won by group subsidiary Bentley.

Diesel engines are very powerful, yet consume little fuel. These are useful advantages in long-distance races such as the Sebring Twelve Hours or the Le Mans 24 Hours. "The market for diesel passenger vehicles in the U.S. is growing steadily. The success of the Audi R10 TDI here in Sebring helps us a lot, therefore, because it so convincingly demonstrates the advantages of modern diesel technology," says John Moulton, President of the Powertrain Division of the Bosch U.S. subsidiary.

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 specialises 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.
