Summary

In developing the first mass-production full electric drivetrain, Audi is going down entirely new roads with its in-house development of electric axle drives, high-voltage storage systems and charging systems. Featuring one drive on each axle, the full electric drivetrain embodies Audi’s core competency – the quattro drive – in a new and impressive way.
Electric motors, power electronics and axle gears incorporating a high degree of component sharing form the basis for a completely new final drive kit. The electric axle drives are manufactured at Audi’s own engine/electric motor plant by Audi Hungaria.
The 95 kWh 400 V high-voltage storage system is likewise an Audi in-house development. To create a 360° system offer, numerous services and wide-ranging charging options were developed with up to 150 kW charging power based on DC quick-charging.
