The Sauber-Mercedes C9 is known around the motorsport world for two things: The car to give Mercedes-Benz it's only Le Mans win in 1989, and having one of the most brutal-sounding engines in Group C History. It was not an instant success, as it was a culmination of good partners at the right time, and with a fresh sen t along the way.
The partnership started in 1987, with the combination between Swiss' Peter Sauber and Mercedes-Benz resulting in the potent chassis and aerodynamics of Sauber's engineers ,and the creation of a over 800HP twin turbo 5.0L M119HL from Mercedes-Benz' E500-Series.
