24 Hours of Le Mans 2014 | AUDI R18 e-tron quattro Animation
Audi has been competing at Le Mans since 1999 in order to achieve sporting success with technological innovations. Never before has an LMP1 race car sporting the four rings been as light, fuel-saving and efficient as the current Audi R18 e-tron quattro. As required by the regulations, its fuel consumption per 100 kilometers has to be up to 30 percent lower than that of the previous models. Despite these tough requirements, Audi is endeavoring to battle for its 13th victory in the Le Mans 24 Hours on June 14 and 15.
Audi has been setting efficiency standards with its ultra technology. Since 2001, TFSI gasoline direct injection helped to considerably reduce fuel consumption at Le Mans, and subsequently in Audi's production automobiles as well. Since 2006, Audi caused a sensation with the TDI engine and five victories at Le Mans. Since 2012, the diesel hybrid drive of the R18 e-tron quattro has been unbeaten at La Sarthe. The next major step results from the efficiency regulations in 2014. Fundamentally new rules determine that Audi and its rivals in the battle for overall victory have to economize on fuel -- up to 30 percent less is available this year, depending on the concept and rating. And this requires a highly efficient race car.

Audi has developed a fundamentally new sports prototype for 2014. The leading innovations include the Audi laser light. This pioneering technology further improves active vision and is simultaneously introduced in the Audi R8 LMX (fuel consumption combined in l per 100 km: 12.9; CO2 emissions combined in g/km: 299). For the powertrain, Audi, in the 25th year of the TDI engine, has developed a new 4.0-liter V6 unit for Le Mans. It has been purposefully designed for efficiency and, together with many other optimizations of the race car, such as aerodynamics, helps save energy. Compared with the 2006 5.5-liter V12 Audi R10 TDI, the first TDI engine used at Le Mans, the current race car consumes about 40 percent less fuel -- while achieving comparable lap times.
