Electric wheel hub drive of the Mercedes Mixte and Mercedes Electrique models, developed by Ferdinand Porsche, Technical Director of the Austrian Daimler-Motoren-Gesellschaft from 1906. As of 1907, the vehicles are built in a small series. In the Mixte hybrid vehicles, the combustion engine drives a generator that supplies electrical energy to the wheel hub motors. In a two-seater forerunner of the Mercedes Mixte based on a Lohner-Porsche with a Mercedes 28 hp engine, Porsche competes in the Exelberg Race in Lower Austria on 11 May 1902 and wins the large car class.
