A udi R18 E-Tron Quattro is the name of this new Le Mans prototype, which will make its racing debut on May 5 at the 6-hour race in Spa-Francorchamps (Belgium) and on 16/17 June fights for the overall victory at the 24 Hours of Le Mans.

Audi R18 as hybrid and lightweight version

The new Audi R18 E-Tron Quattro comes with a completely new drive philosophy . The rear axle is driven conventionally, the front axle by electric motors. In the Audi R18 E-Tron Quattro, kinetic energy is recovered on the front axle in the braking phases. It is fed electrically into a flywheel storage device and called up again via electric motors when accelerating from a speed of 120 km /h. Meanwhile, a V6 TDI unit with more than 510 hp tugs on the rear axle.

Parallel to the Audi R18 E-Tron Quattro, Audi Sport developed the Audi R18 Ultra -
because Audi drives in the 24 Hours of Le Mans and in the newly created FIA World Endurance Championship (WEC) in Two-pronged this year - the 2012 Audi R18 is available with and without a hybrid drive. The highlight: Both vehicles are fundamentally identical, so the logistical effort for Audi Sport and the emergency team is limited.

The additional designation Ultra stands for consistent lightweight construction - the R18 should even be the lightest Le Mans prototype that Audi has ever built. This was also necessary to compensate for the additional weight of the hybrid components for LeMans use. The lightweight innovations include a gearbox with a CFRP housing.

Audi with four R18 in LeMans

At the 24 Hours of Le Mans 2012, Audi Sport Team Joest will field two R18 E-Tron Quattro and two R18 ultra. The two hybrid vehicles will be driven by last year's winning trio, Marcel Fässler (CH), André Lotterer (D) and Benoît Tréluyer (F), as well as the 13-time Le Mans winners Dindo Capello (I), Tom Kristensen (DK) and Allan McNish (GB) piloted. New signing Loïc Duval (F) starts together with Timo Bernhard (D) and Romain Dumas (F) with an R18 ultra, as do Marco Bonanomi (I), Oliver Jarvis (GB) and Mike Rockenfeller (D).
