In addition to the V10-powered R8 sports cars, Audi has unveiled an
electrically-powered R8 e-tron at Geneva.
The car achieves a performance figure of 456 hp (340 kW) and a torque of 678 lb-ft (920 Nm). It sprints from a standstill to 60 mph in 3.7 seconds. Thanks to new battery cells, the range could be more than doubled compared to the first version - it is now more than 280 miles (450 kilometers).
Thanks to targeted modifications to the outer shell and on the wheels, the Audi R8 e-tron achieves an aerodynamic drag coefficient (cd) value of 0.28. In terms of performance and range, the car enters entirely new dimensions.
The large T-shaped battery is structurally integrated into the center tunnel and behind the occupant cell. Audi produces the high-voltage battery itself, for the first time based on a newly developed lithium-ion technology which was specially conceived for a purely electric vehicle drive. In comparison to the first technology platform, the battery capacity has grown from 49 kWh to approximately 92 kWh.
Audi uses the electrical high-performance sports car primarily as a mobile high-tech laboratory. Accordingly, the findings from the R8 e-tron help in creating a vehicle with a sedan character. Upon customer request, the R8 e-tron will be available for order in 2015 as an electrically powered sports car in hand-built quality.
