Splendid driving performance is ensured by the Audi R8 e-tron sports car, which is purely electric and high-powered. It is a quattro for it integrates four asynchronous motors, two each on the front and rear axles and power is transmitted via short input shafts and a single-staged transmission. It embodies the fundamental strength of quattro technology. The four motors allow torque vectoring, the selective acceleration of individual wheels and therefore active distribution of torque. The R8 e-tron is a holistic concept that extends far beyond the battery technology, offering a complex interaction of components significantly affecting road capability, range and efficiency. A high output is provided by the rechargeable lithium-ion battery which consists of single cells and enables a range of 250 km when it is operated in the NEDC cycle. A household current with 230 volts is enough for the recharging of the battery and it takes six to eight hours if the battery is completely discharged.
The front section of the car model is governed by the trapeziod of the single frame and is described by 1.90 metres width, 1.25 metres in height and measures 4.43 metres in length. Its body is aluminum and was designed with Audi Space Frame technology, resulting in 1,600 kg incredible weight. The driving mode is showed through a graphic display and the driver is able to select the level of recuperation by means of one-touch switches on the steering wheel.
The limited edition of the R8 e-tron will hit the roads at the end of 2012.
