Audi showed off an e-tron prototype in the form of an R8 during the Le Mans race this year. Racing legend Frank Biela took the e-tron out for a spin in the Le Mans vers le futur demo event for EVs.

The R8 e-tron is powered by four motors connected to a wheel each for quattro grip. Combined, they provide 313 hp and 4500 Nm of torque (no it’s no a typo), propelling the two-seater from 0-100 km/h in just 4.8 seconds. 70% of power goes to the rear wheels while the rest goes to the fronts. The battery sits behind the passenger cabin for a 42:58 weight distribution.

Torque vectoring from the four motors mean that understeer and oversteer can be corrected by not only targeted activation of the brakes, but also by precise increases in power by few milliseconds. The R8 e-tron is claimed to remain extremely neutral even under great lateral acceleration, “hustling through corners as if on the proverbial rails” according to Audi.

The car’s lithium-ion battery can be charged from a household plug socket (230 volts/16 amperes), taking six to eight hours to be refilled. Kinetic energy from the brakes is recuperated, channelled to the alternator and converted into electrical energy.
