Protean Electric, the global leader of advanced in-wheel electric drive, partnered with MAHLE-Powertrain to construct and develop a plug-in hybrid electric vehicle (PHEV).
The Through-the-Road Parallel Hybrid Demonstrator Vehicle (TTR) equipped with ProteanDrive shows the benefits of adopting in-wheel electric motors in a passenger car. In the TTR transmission, similar to the BMW i8, the electric and ICE propulsion combines through traction with the road, having no mechanical linkage within the vehicle.
This ‘through the road’ parallel drive arrangement allows the vehicle to be operated in three distinct driving modes:
- Full electric rear wheel drive with zero tailpipe emissions
- Conventional engine front wheel drive for highway use
- Full hybrid all-wheel drive for maximum performance and traction
Since Protean Electric and MAHLE Powertrain successfully converted this standard gasoline powered vehicle, Protean has further enhanced the ProteanDrive motor performance to produce 1250Nm & 80kW per wheel motor. Through the retuning of the suspension Protean Electric has demonstrated that driving dynamics, contrary to popular belief, do not suffer as a result of adding in-wheel motors and can actually be enhanced by independent torque vectoring control.
