Hotchkiss was an American who went to France in 1867 to set up an arms factory which turned into the building of cylinder blocks for Panhard. Soon he was making his own vehicles. Hotchkiss also invented the drive train (transmission output shaft to and including the rear end) still used in rear-wheel drive vehicles today like pickup trucks. Hotchkiss built his first car in 1903 and the cars were noted for their round, barrel-like radiator. It has a 4.7-liter four-cylinder engine of about 25 hp.
