Audi R15 TDI – More fuel efficient and even faster than its dominating predecessor, the R10.
INGOLSTADT, Germany -- AUDI is the world’s first automobile manufacturer to develop a “second” generation diesel racing sports car. Audi aims to underline its supremacy and consolidate its expertise in car technology once more at the legendary 12-hours of Sebring and 24 Hours of Le Mans with the all-new Audi R15 TDI.
This years 24 Hours of Le Mans will require more efficient race cars requiring lightweight construction, environmentally friendly drive concepts and well-thought out aerodynamics.
Audi Sport is placing an all-new LMP1 race car on the track that differs significantly from all previous Le Mans sports cars. “The R15 TDI has many detailed technical solutions never seen before on a sports prototype,” explains Head of Audi Motorsport Dr. Wolfgang Ullrich. “To a certain extent we followed entirely new routes.”
Highly efficient TDI engine
The heart of the R15 TDI is a newly developed V10 TDI engine producing more than 600 HP, with a maximum torque output in excess of 775 lb-ft. The power plant is more compact and lighter than the twelve-cylinder engine used in the preceding R10 TDI model while the specific fuel consumption has been reduced. Innovations in the turbo-charging and fuel injection areas ensure improved engine response. The R15 TDI is also equipped with a new generation of even lighter weight diesel particle filters (DPF).
The R15’s aerodynamics have also been improved. Like the 2008 championship winning Audi A4, the airflow around and through the car was optimized with CFD (Computational Fluid Dynamics).
Innovative vehicle electrical system concept
The R15’s electrical system in the Le Mans car is entirely new. A Li-Ion battery is being incorporated for the first time. It is lighter than the conventional Pb-Acid battery and supplies a higher voltage.
The headlights fitted to the R15 TDI also benefit from the higher power. At Le Mans, Audi competes for the first time with a low beam unit comprised entirely of light emitting diodes (LEDs), which represents the next generation of Audi LED technology for its consumer automobiles.
Audi is the only automobile manufacturer to have won the famous 24 Hours of Le Mans with a diesel car. “With the R15 TDI we have created the base to be in a position to win also in 2009,” says Head of Audi Motorsport Dr. Wolfgang Ullrich.
The Audi R15 TDI celebrates its race debut in the 12-hour race in Sebring, Florida in the USA on March 21. Audi Sport plans to field three cars at the 24 Hours of Le Mans on June 13 and 14.
