From the actual point of view the most promising concepts for future passenger cars are based on the conversion of electrical into mechanical energy. In-wheel motors are an interesting concept towards vehicle electrification that provides also high potentials to improve vehicle dynamics and handling. Beside aspects concerning the electric system (e.g. motor type, energy storage, and control strategy), there are also some open questions related with the mechanical design of in-wheel motor driven vehicles that need to be solved before series production. In this work, the results of a research project being developed at the Institute of Automotive Engineering – FTG – of Graz University of Technology together with MAGNA Powertrain and MAGNA STEYR dealing with the design of an in-wheel motor driven
