The Mercedes-Benz C111 was a series of experimental automobiles produced by Mercedes-Benz in the 1960s and 1970s. The company was experimenting with new engine technologies, including Wankel engines, diesel engines, and turbochargers, and used the basic C111 platform as a testbed. Other experimental features included multi-link rear suspension, 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).[1]
The company decided not to adopt the Wankel engine and turned to diesel experiments for the second and third C111s. The C111-IID produced 140 kW (188 hp) and was based on the 240D W115 model OM616 engine. The C111-III was powered by a 170 kW (228 hp) at 4,500 rpm straight-five OM617 turbocharged diesel that broke nine diesel and gasoline speed records. With more aerodynamic bodywork that gave it an air drag coefficient of 0.191,[citation needed] the C111 eventually reached 322 km/h (200 mph) at the Nardò Ring in 1978, and averaged 16.0 liters/100 km at 316 km/h (14.7 mpg at 195.4 mph) over a 12-hour cruise. A later 373 kW (500 hp; 507 CV)[clarification needed] 4.8 L twin KKK-turbocharged V8 version set another record, with an average lap-speed of 403.78 km/h (250.958 mph). This was achieved by Hans Liebold in 1 minute, 56.67 seconds on May 5, 1979.[2]
Total production was 16 cars: 13 first and second generation Wankel engined cars, 2 diesel engined third generation cars used in the Nardo record attempt, and a single V8 engined fourth generation car.[3]
Mercedes-Benz introduced the C112 at the Frankfurt Motor Show in 1991 as a proposed production sports car. The car used a mid-mounted 6.0 L V12 engine. After accepting 700 deposits, the company decided not to proceed with production.
