The project, dubbed Schaeffler Hybrid, is part of an innovative project that allows a comparison between the multiple new energy mobility options, demonstrating various vehicle configurations and driving conditions.
In addition to the Corsa’s internal combustion engine, the car uses a central electric motor and two wheel hub motors. Also, it features a 16 kWh lithium-ion battery (400V, 400 A), which can be charged using the vehicle’s kinetic energy recovery system, the range combustion unit or an external power supply (the car is a plug-in hybrid).
The central unit is flange located to the automated manual transmission by means of a toothed chain and drives the front wheels. The unit comprises a liquid-cooled 50 kW and 95 Nm electric motor, while the wheel motors have an output of 50 kW each and a torque of 530 Nm. The two motors form a compact unit that integrates wheel bearing, drive and brake. This solution has the advantage of being suitable for integration into an existing vehicle platform with minimum changes.
The vehicle uses an automated manual transmission, which uses bespoke clutch products that have been developed especially for hybrid vehicles. In addition to that, it offers multiple driving modes that combine the different power units.
“Presenting various concepts with informative comparisons as well as realistic testing played a decisive role in the implementation of the Schaeffler Hybrid”, says Prof. Dr. Peter Gutzmer, Member of the Executive Management Board responsible for technical development at the Schaeffler Group.
The vehicle will not enter series production, as it has been developed to showcase various technologies.
