The Audi e-tron prototype combines enormous power and high efficiency. With a system output of up to 300 kW, the full-size SUV with a fully electric drive accelerates from zero to 100 km/h in less than six seconds. In the WLTP test cycle, it covers more than 400 kilometers on one battery charge. One important factor for the long range is the most innovative recuperation concept among the competitors. The electric SUV proved this with an impressive performance at Pikes Peak.
The recuperation system contributes to up to 30 percent of the electric SUV’s range. It involves both the two electric motors and the electrohydraulically integrated brake control system. On its 31 kilometer downhill drive, the electric SUV feeds so much energy back to the battery that it can cover approximately the same distance again. The difference in altitude of about 1,900 meters provides the necessary conditions for this. The Audi e-tron prototype recuperates energy with up to 300 Nm of torque and 220 kW of electric power – more than 70 percent of its operating energy input. No series production model has achieved such a value up to now.
