Audi has produced ten R8 e-tron models, but none will be offered to customers. Instead, the ten will be used exclusively for internal testing and development.
The Audi R8 e-tron is a high-powered sports car with a purely electric drive. Its four engines provide a total power of 230 kW (313 hp) for splendid driving performance. They can be individually actuated – for an entirely new developmental stage of the permanent four-wheel drive.
Torque vectoring helps the R8 e-tron corner as quickly as any electric car has a right to, and contributed to its production car lap record at the Nürburgring circuit in Germany last year.
The 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 R8 e-tron delivers breathtaking driving performance. It catapults from 0 to 100 km/h (62.14 mph) in just 4.8 seconds.
A top speed is electronically limited to 124.27mph and, in optimal conditions, the R-8 e-tron is capable of covering 133.59 miles.[source: Autocar]
