Audi R10 TDI
The Audi R10 TDI is a racing car of the automobile manufacturer Audi. It was introduced at the beginning of the racing season in 2006 as the successor to the Audi R8 and replaced at the start of the motorsport season 2009 from the Audi R15 TDI, but in the European Le Mans Series and at Le Mans by the private team Kolles 2009 continue to be used. 2010 denied the Audi R10, only the 24 - hour race at Le Mans.
History
The Audi R10 2006 was the first racing car in the history of the 24 Hours of Le Mans, who won the overall victory with a diesel engine. The presented in Paris on 13 December 2005 race car is powered by a new 5.5 -liter twelve-cylinder TDI engine with twin turbochargers. With more than 475 kW and 1200 Newton meters of Le Mans prototype surpasses the performance of the majority of previous Audi racing cars - including that of its victorious R8 predecessor. The V12 engine casing is made entirely of aluminum.
Equipped with two particulate filters V12 engine of the R10 is hardly noticeable by its quietness from the outside as a diesel generator. The engineers at Audi Sport presented the specifics of the TDI engine but a whole range of challenges. Thus, the injection pressure of the common rail injection is much higher than those of 160 MPa, which are reached in the series. The usable speed range is 3000-5000 rpm to over a gasoline race engine at a relatively low level. Thanks to the favorable torque curve of the TDI engine, the driver of the R10 much less frequently than in the R8.
The maximum torque of 1.2 kilo Newton meters makes special demands on the R10 - even the engine dynamometers at Audi Sport had to be converted to other gear to cope with these high torque loads.
Also, the chassis of the car had to be adjusted: the R10 compared to the R8 a much longer wheelbase. So far unique for a Le Mans prototype, the extra-wide front tires. New technologies have also been applied in the development of carbon-fiber monocoque. Chassis, engine and transmission form a torsionally stiff, fully supporting unit.
First tests were conducted in late November 2005. By the 24 - hour race at Le Mans on 17-18. June 2006 completed a test program, which also includes an insert at the 12 Hours of Sebring on March 18, was one in which a car, piloted by Marco Werner, Emanuele Pirro and Frank Biela, after 117 rounds failed due to engine overheating. The second car drove with the team Rinaldo Capello / Allan McNish / Tom Kristensen to overall victory with a total of 349 laps, four laps ahead of the runner. The Reinhold Joest's team supports the development team from Audi Sport as already in the R8 project.
2007 Fuel tank capacity was reduced by the regulations by 10%; the tank volume decreased from 90 to 81 liters thereby. This was done to account for the 10% higher heating value of diesel fuel compared to racing fuel. As a result, use of a rule change in the ACO in 2007 had diesel vehicles of LMP category from 2008 bio-diesel.

24 - hour race at Le Mans
With the Audi R10 TDI won in 2006 for the first time a diesel engine at a 24 Hours of Le Mans. 235,000 spectators, Frank Biela, Emanuele Pirro and Marco Werner brought the sixth Le Mans victory for Audi. Rinaldo Capello, Tom Kristensen and Allan McNish drove to catch up before the third. The R10 TDI could enter 2007 with the same team as in 2006 with Frank Biela, Emanuele Pirro and Marco Werner seventh success for the brand. 2008, the third overall victory with the Audi R10 TDI at Le Mans was achieved. The drivers were Tom Kristensen, Allan McNish and Rinaldo Capello.
Petit Le Mans 2006
For the first time a diesel sports car won the American endurance classic " Petit Le Mans". With the victory at Road Atlanta in the U.S. state of Georgia Audi secured by the driver and team standings prematurely the Manufacturers' Championship in the LMP1 class of the American Le Mans Series. The new Audi R10 TDI was in the seventh race unbeaten and won in his first season after the 12 Hours of Sebring in March and the 24 Hours of Le Mans in June, the third major endurance race of the year.
