Meet the C112 prototype which is one of Luigi Colani’s (German industrial designer) Le Man’s proposals. The C112 was based on the rotary-engined Mercedes Benz C111 but was radically aerodynamic with a drag coefficient of only 0.2, half that of a Porsche 917 of the same era.
What makes this prototype unique is that it is more like a jet fighter than a car. The driver occupies an almost reclining position in it, and the entire rear is almost striking with its dimensions with a giant wiper and a series of exhaust pipes at the forefront.
