The Hippomobile is an early, three wheeled automobile invented by Jean Joseph Étienne Lenoir in France in 1863 which carried its own internal combustion engine. It was based on his 1860 invention, the Lenoir gas engine.
History In 1863, the Hippomobile, with a coal gas fueled, one-cylinder internal combustion engine, made a test drive from Paris, France to Joinville-le-Pont, which covered around eleven miles in less than three hours, which was a fair achievement at the time.Data on Hippomobile and hydrogen/fuel cells, TÜV SÜD Industrie Service GmbH de Rivaz, Lenoir and Delamare-Debouteville
