At the tender age of 25, well before his work with the Auto Union Type C, Ferdinand Porsche entered the 1900 Paris World Exhibition with his all-electric car after developing the key systems for Jacob Lohner & Company. It was heralded as the "most innovative invention" of the show and consequently orders were filled for 300 of the cars. With 1800 lbs of lead-acid batteries, it's quite amazing the cars would routinely achieve a staggering for the time top speed of 31 mph. Since the motors were an in-wheel system, there was really no problem to include a second set in the back for the purposes of racing.
The Lohner-Porsche petrol-electric 'Mixte' used a petrol engine rotating at a constant speed to drive a dynamo, which charged a bank of accumulators.
These, in turn, fed current to electric motors contained within the hubs of the front wheels.Therefore there was no need of drive shafts, transmission, gears, straps, chains,or clutch. Due to its extreme simplicity the transmission operated, therefore, without losses produced by mechanical friction with an incredible yield of 83%.
