Sauber Mercedes C11 Group C Pure Sound at Monza Circuit!

The Mercedes Benz C11 was a Group C prototype race car introduced in 1989/90 for the World Sportscar Championship. Built by Sauber as a successor to the Sauber C9, the C11 was the first time that Mercedes Benz chose to put their name on the car, instead of simply using Sauber. The car in the video is chassis which was built in late summer 1989 for the 1990 WSPC racing season. But as soon as the car was completed the FIA changed the technical regulations for the 1990 season which means the car would have needed other modifications in order to respect the new regulations. Rather than modify this chassis, Sauber decided to use it as the prototype C11 test car. was used at 10 tests with all the official factory drivers driving it at some point (Mario Baldi, Michael Schumacher, Jochen Mass, Jean Louis Schlesser, Heinz H. Frentzen, Karl Wendlinger). It was never raced, all the major development work on aerodynamics and general chassis set up for the C11 programme was carried out with this car.
