The e-tron will be powered by three electric motors, which share a similar underpinning to Porsche's upcoming Mission E. Two of those motors will drive the rear wheels, while the third will power the front. If the E-tron uses a similar set up as their quattro concept, then we can expect the car to offer around 496bhp. This will make it capable of a 4.5 second 0-60 sprint and a top speed of 131mph.
