Mercedes-Benz C 111

Franfurt am Main, 1969: What Mercedes-Benz unveiled to an international public at the IAA in Frankfurt was nothing short of a "test lab on wheels". With its high unswept gulwing doors, marked wedge shape and metallic orange paintwork, the C 111 proved a visitor magnet from day one of the show.

Other innovations included a body of fiberglass-reinforced plastic and a powerful three-rotor rotary engine capable of outstanding performance: 280 hp (206 kW), 163 mph and 0-62 in 5 seconds. This made the C 111 a genuine super sports car.

But despite the many blank cheques received, one thing was clear: the Stuttgart company was never going to develop this sensational car for mass production.

Instead, the C 11 became the grandfather of future research vehicles, whose findings have had a major impact on the development of many production models.
