Mercedes-Benz C11

The Mercedes-Benz C11 is a Group C prototype race car that Sauber built for the 1990 World Sports-Prototype Championship as successor to the Sauber C9, and it was the first time Mercedes-Benz put its own name on the car instead of simply using Sauber. It kept the C9's 5.0 litre twin-turbo M119 V8 but had a carbon fibre chassis designed from scratch by Leo Ress, with more downforce, a lower frontal area and a transverse push-rod rear suspension. In race trim the engine produced about 730 horsepower. The car was the last Group C prototype of the Sauber Mercedes team before the introduction of the 3.5 litre category, and it generated 26.2 kN of downforce at 320 km/h.
