2012 Audi R8 E-tronThe four asynchronous motors - two each on the front and rear axles - make the Audi R8 e-tron a quattro. Power is transmitted to the wheels via the single-staged transmission and short input shafts. With a peak output of 230 kW (313 hp) and with up to 4500 Nm (3319.03 lb-ft) torque at the wheels available from a standstill, the Audi R8 e-tron delivers breathtaking driving performance. It catapults from 0 to 100 km/h (62.14 mph) in just 4.8 seconds.

The technology demonstrator enveloped by the R8 belongs to the top league of electric sports cars. Its package does justice to the specific qualities of the new technology in all details. The large, fluid-cooled lithium-ion battery and the power electronics, for example, lie directly behind the passenger compartment. The result is an optimal center of gravity and a load distribution of 42:58 between the front and rear axles - just like the series production R8 with its 5.2 liter FSI. The R8 e-tron provides a glimpse into Audi's philosophy of electric mobility. Extending far beyond the battery technology and the replacement of an internal combustion engine by an electric driveline, the concept is holistic. The complex interaction of all components crucially affects the factors of efficiency, range and road capability.
