Rally success for E-Wheel Drive concept car

Rally success for E-Wheel Drive concept car Schaeffler's Fiesta E-Wheel Drive concept car successfully competed against other electric vehicles in the 4th Silvretta E-Car Rally in Montafon, Austria. The car finished ahead of other electric vehicles, some of which are already in volume production.

The Silvretta E-Car Rally is an annual three-day race between electric vehicles over three Alpine stages. The drivers must economise on the use of kilowatts, volts and amperes in order to avoid penalty points and to finish with sufficient battery charge. The Fiesta E-Wheel Drive concept car is the result of a collaborative project between Schaeffler and Ford. The concept car is powered by two highly integrated wheel hub drives installed in the rear wheel arches.

All components required for driving, deceleration and safety - such as electric motor, power electronics, controller, brake and cooling system - are mounted to the wheel rims. These provide power outputs of 40 kW per drive, and a continuous output of 2x33kW, which equates to 110hp and 90hp respectively. The liquid-cooled wheel hub drive delivers up to 700Nm of torque. The electrical voltage of the high-voltage drive is 360-420V.

Schaeffler's CTO Prof. Peter Gutzmer, who shared the cockpit of the concept car with Prof. Pim van der Jagt, managing director of Ford Research and Advanced Engineering, comments: "Schaeffler wanted to gain additional experience in terms of the level of development of the wheel hub drive, which is intended for urban electric vehicles of the future. We completed this challenging three-day rally with a pre-production model without any problems, even on long, steep hill climbs and during downhill driving with energy recovery - a significant advantage offered by electric vehicles."
