The drivetrain provides the necessary propulsion for the racing car. We have opted for a drive concept with four wheel hub motors. Each wheel has an assembly consisting of an electric motor and planetary gearbox, which are individually controlled by a driving dynamics control system.
Electrical motor
- Water-cooled electric motors with a peak output of 35 kW
- Efficient operation thanks to inverters developed in-house
- Direct connection to the gearbox
Wheel hub gear
- Self-developed stepped planetary gearbox, which reduces the engine speed from 20,000 rpm and provides 350 Nm of torque for a short time for the drive
- Integration of the gearbox in the wheel carrier for compact packaging in the wheel assembly
- Top speed of 125 km/h
A particular focus during gearbox development was to achieve the smallest possible installation space and high efficiency. The case-hardened gears ground to gear quality 4 make a particularly positive contribution here
