The Mercedes-Benz C111 is a series of experimental automobiles produced by Mercedes-Benz in the 1960s and 1970s. The company was experimenting with new engine technologies, including 3 and 4 rotor Wankel engines, diesel engines and turbochargers. The C111 platform was the testbed for these technologies. Further experimental features included multi-link rear suspension, modern gull-wing doors and a luxurious interior with leather trim and air conditioning.
The first version of the C111 was completed in 1969. The car used a fiberglass body shell and with a mid-mounted three-rotor direct fuel injected Wankel engine (code named M950F). The next C111 appeared in 1970. It used a four-rotor engine producing 257 kW (350 hp). The car reportedly could reach a speed of 300 km/h (186 mph).
The company decided not to adopt the Wankel engine and turned to Diesel experiments for the second and third C111s.
