In 1970, Colani proposed an alternative supercar project to Mercedes-Benz, which had shown a concept C 111 central engine coupe powered by a Wankel rotary piston engine the year before.
I must say that despite the shape and color, more reminiscent of a product from a sex shop, the car turned out to be very streamlined: the drag coefficient Cd was only 0.2 - half that of sports cars of that time.
