The history of hybrid vehicles is perhaps longer than you might think.

The Lohner-Porsche Mixte Hybrid was the first hybrid vehicle developed by Ferdinand Porsche. It was produced from 1900 to 1905.

The first prototypes were two-wheel drive, battery-powered electric vehicles with two front-wheel hub-mounted motors. A later version was a series hybrid using hub-mounted electric motors in each wheel, powered by batteries and gasoline-engine generator.
