Audi R18 e-tron quattro

Audi R18 e-tron quattro: Comeback of quattro drive in motor sport. Audi R18 ultra: ultra light evolution of a Le Mans winner.

The R18 e-tron Quattro has the same form as the R18 Ultra, but with one important difference: its TDI diesel engine is assisted by a regenerative braking system that gives it not only hybrid power but all-wheel drive.
