- Sauber C9
The Sauber C9 (later named the Mercedes-Benz C9) was a
Group C prototype race car introduced in 1987 as a continuation of the partnership betweenSauber as a constructor andMercedes-Benz as an engine builder for theWorld Sportscar Championship . The C9 replaced the previousSauber C8 .For its debut season in 1987, the cars were run by Kouros Racing, named for after theaftershave brand of its sponsor, although officially backed byMercedes-Benz . The team managed a mere twelfth in the teams standings, scoring points in only a single round. For 1988, Kouros was dropped as a sponsor, forcing the team to be renamed Sauber Mercedes. As a result, Mercedes involved one of its company AEG-Olympia for sponsor. However, they managed to finish second in the championship behind Jaguar, with five wins for the season. Unfortunately at the24 Hours of Le Mans , the team suffered an embarrassing setback when they were forced to withdraw due to concern over theirMichelin tires.Finally, in 1989, the car was able to achieve great success. Beside replacing the black color scheme for its national plain silver scheme, reducing AEG as a minor sponsor, the older
Mercedes-Benz M117 5.0Lturbocharge d V8 engine was upgraded to the M119, which replaced steel heads with new aluminium. The C9 was able to win all but one race in the 1989 season, including the 24 Hours of Le Mans. During qualifying for Le Mans, the C9 recorded a speed of 247mph (398km/h) while on the Mulsannes Straight, a record which led to the addition of two chicanes on the Mulsanne straight. Mercedes driverJean-Louis Schlesser would end up taking the driver's championship that season.The C9 would be replaced by the
Mercedes-Benz C11 for 1990.Le Mans Results

These dangerous speeds led to the interruption on the huge initial Le Mans Mulsanne Straight with the present two chicanes, from 1990 on.
The C9 has only been surpassed by the WM Peugeot prototype, with a speed of 251.1 mph (405 km/h) in the 1988 race [ [http://www.mulsannescorner.com/maxspeed.htm Mulsanne's Corner: Maximum Speeds at Le Mans, 1961-1989 ] ] . However the WM car was nearly undrivable elsewhere on the circuit and the engine was soon destroyed from a lack of cooling. Therefore C9 still holds the fastest record on track racing in LeMan until today.
