2011 Audi R18 TDI

INTRODUCTION:Since its debut in 1999, the brand with the Four Rings has won the world's most important endurance race as many as nine times with the R8, R10 TDI and R15 TDI models. In doing so, Audi has equaled this feat in the race's roll of honor with Ferrari. With the new R18, which was presented at the Audi Sportpark in Ingolstadt on the evening of Friday, December 10, 2010, Audi is aiming for its tenth Le Mans success in 2011.

HIGHLIGHTS:The R18's headlights, which are the first to completely consist of LEDs with optimized amount of light, are a technical highlight. The new generation of headlights was developed in close cooperation between Audi Sport and the Technical Development (TE) division of AUDI AG and by using at Le Mans, will be prepared for future use in production vehicles. Audi's light designers had the chance to make their mark on the development as well: The LEDs of the daytime light form the shape of a "1" which is intended to inspire associations with Audi's historic brand logo.

SPECIFICATIONS:

• Significantly smaller engines than those used before will be prescribed at Le Mans in 2011 as the rule makers aim to achieve a substantial reduction of engine power. By opting for a 3.7-liter V6 TDI unit, Audi retains the diesel concept that saw its first victorious fielding in 2006. "From our point of view, the TDI continues to be the most efficient technology," says Ulrich Baretzky, Head of Engine Development at Audi Sport. "There are good reasons why the share of TDI units among Audi's production models is as high as it is."
• Another new development is the six-speed transmission in the R18 which has been specifically modified for use with the smaller engine.With regard to the chassis Audi Sport wants to live up to its promise, expressed in the brand's "Vorsprung durch Technik" tagline. Unlike those of the closed Le Mans prototypes, the carbon fiber monocoque of the R18 does not consist of two halves but features a single-component design. This saves weight and increases stiffness.

DESIGN:The Audi R18 has been designed for progressive electrification, which Audi Sport is planning to drive forward step by step. "But efficiency is always the crucial factor for us," says Dr. Wolfgang Ullrich. "No matter which form of energy recovery we may choose the key aspect for Audi - in motorsport as well as on the production side of the house - is that it provides a true advantage."
