World premier unveling at Paris: Audi R10
V12 TDI engine delivers over 650 HP
First tests with this new engine have been successful
Audi is once again one step ahead competition: the company will become the first car maker in the world to fight for victory in the endurance race of 24 hours at Le Mans using a diesel powered vehicle. The new Audi R10 which will be presented at Paris on 13 December is powered by a brand new diesel engine, 5.5 litres, V12 TDI, twin-turbo, fuel saving and silent.
The Le Mans Prototype having a maximum power above 650 CP and more than 1100 Nm torque exceeds previous Audi racing engines including the previous R8. Audi ventures in an uncharted teritory of diesel engines building a V12 entirely of aluminium. The same way Audi proceeded with the TFSI technology which triumphed at Le Mans before it was taken into production, it is expected to happen the same thing with this V12.
"With A8 4,2 TDI Quattro Audi is building already one of the most powerful diesel engine powered car in the world", explained Martin Winterkorn, president of the administration council of Audi, at the R10 presentation at Paris. "The Le Mans Project will allow our specialists to obtain more out of the TDI tehnology. At this time one out of tow Audi cars sold is powered by a diesel engine. We expect a growth in the diesel percentage in the future"
The V12 TDI engine of R10 is equipped with two particulate filters and is hard to recognize as a diesel engine because its refinement. Audi engineers have taken the characteristics of the TDI street engines to a whole new level. The injection pressure exceeds 1600 bar. The power band is limited below 3000 and 5000 rpm, very low for a competition car. This way the R10 pilot will shift gears much less often than in a R8 thanks to the generous torque response of a diesel engine.
The huge torque of 1.100 Nm creates difficulties for the transmission of the R10. Even the newest tehnology of dynamometres from the Audi Sport garages had to be re-equiped to face this engine's torque.
More, there had to be made major changes to the chassis of the car. Audi R10 has a longer wheel base than R8. The front tyres, extremely wide are unique for a Le Mans prototype. There have been implemented new tehnologies in developing the mono-block carbon fiber body. The chassis, engine and transmission form a very rigid unit.
"The R10 project is our biggest challenge yet for the Audi Sport division." said Audi Motorsport director, Dr. Wolfgang Ulrich. "The TDI Tehnology has not been yet pushed to its limits in motorsport. We are the first to try this. The demands for such a project are still very large. Therefore our long term partners, such as Bosch, Michelin or Shell support us in our goal. Together we have the opportunity to write new chapters in history of motorsport and diesel tehnology".
The new Audi R10 has finalized succesfully its first session of test at the end of November. A very intense test program including the participation at the 12 hour race at Sebring (USA) on 18 March has been prepared for the 24 hour race at Le Mans which will take place at 17/18 June 2006. The Audi Sport team in charge with the development of this new race car is supported by the Reinhold Joest's team which was in charge of the R8 project.
