It was a record breaking super sports car. The experimental vehicle with the magic code C 111 stood up to every challenge between 1969 and 1979. Painted in a contemporary orange, the C 111 was a seventies child.
It was a tester of a Wankel engine, a turbo-diesel engine and an internal combustion engine but it did not go to the salesrooms, instead it found its way ino the Guinness book of world records.
In 1978, it clearly demonstrated the efficiency of the turbo-diesel engine by winning 9 world records.The C 111 served to test the Wankel engine. A three-rotor unit developing 206 kW (280 hp) provided the propulsion power and permitted a top speed of 260 km/h (162 mph) – quite remarkable for the time.
Just a few months later a thoroughly revised version of the C 111 was shown at the Geneva Motor Show. It featured a four-rotor Wankel engine with an output of 257 kW (350 hp). The car accelerated from standstill to 100 km/h (62 mph) in 4.8 seconds and attained a top speed of 300 km/h (186 mph).
The record-breaking C 111-IV of 1979 came with further aerodynamic refinements, additionally featuring distinctive spoilers, a changed front end and two tail fins. Its propulsion unit was a 4.5 litre V8 engine from regular production, enlarged to displace 4.8 litres and generate 367 kW (500 hp).
In this version the C 111-IV was no longer a pure research vehicle but one that achieved top-class sporting performance.Constantin von Kageneck from the Mercedes-Benz Classic Center takes Jay under the hood of his dream car, the rare Wankel-engined, ’70s supersports C111.
