“In the future, aerodynamic efficiency will be even more important at Le Mans than it was in the past”, says Head of Audi Motorsport Dr. Wolfgang Ullrich. “A closed car has clear advantages in this respect. Our computer simulations have been confirmed in the wind tunnel and during initial track tests”.
Unlike its predecessor, which had a 5.5-liter V10 diesel engine, the new model uses a much smaller, 3.7-liter V6 TDI, mated to a modified six-speed transmission.
The R18 features a one-piece carbon fiber monocoque, which saves weight and increases stiffness. Audi says that the chassis and aerodynamics were developed with a lot of know-how borrowed from the previous R models.
The Audi R18 was given the green light in mid 2009, while engine testing began in summer 2010. The first track test took place at the end of November, with Allan McNish at the wheel.
The Ingolstadt-based maker plans to enter three cars in next year’s Le Mans, run by Audi Sport Team Joest.
