The second generation of the Audi R8 forms the basis for two more models. Audi has made major engineering developments in its high-performance electric sports car, the R8 e-tron. The latest evolution of the vehicle takes up the multimaterial Audi Space Frame from the new series-production model.

The R8 e-tron achieves an electric range of 450 kilometers (279.6 mi) instead of a previous 215 kilometers (133.6 mi) with an energy density that has been increased from 84 Wh/kg to 154 Wh/kg and some other modifications to the car. The electrically powered high-performance sports car has the Combined Charging System (CCS) on board, which allows charging with direct and alternating current. Using this system, it is possible to fully charge the battery in significantly less than two hours.
