The extremely rare (12 total built) Mercedes-Benz M950F was a normally aspirated Wankel engine mounted in experimental Mercedes-Benz C111 vehicles, built in 1969-70. There were two versions: 3-rotor engine (600 cc each) with power output of 280 hp at 7000/min, and a later version 4-rotor engine (600 cc each) with power output of 350 hp at 7000/min.

The experimental Mercedes-Benz C111 containing the (code named M950F) engine was shown to the public at the 1969 Frankfurt International Motor Show.

This was a totally experimental car from Daimler-Benz, and they gave up on the rotary due mainly to poor fuel consumption.
