Key Data
With the eb014, TUfast built the first all-wheel drive electric vehicle in the club’s history. The complete vehicle is developed around the powertrain. Four permanent-magnet synchronous motors installed on the chassis side transfer the power to the drive shafts by a self-developed two-stage spur gearbox.
