The Mercedes-Benz C11 was a Group C - prototype , the 1990 for the World Cup sports car was introduced. The racing car built by Sauber Motorsport in Switzerland was a further development of the Sauber C9 and was replaced by the biturbo-charged five-liter V8 Mercedes-Benz M 119 HL , the racing version of the M 119 ("HL" stands for high performance), which was already used in the predecessor. driven, which has been further increased in performance for the C11 . For the first time since the W 196 of 1955, when Mercedes withdrew from motorsport , a racing car was officially named "Mercedes-Benz" again.
history
The C11 made its debut in the first race of the sports car world championship in 1990. The Sauber team appeared in Suzuka with a C11 and a Sauber C9 from the previous year and another C9 as a replacement vehicle. However, Jean-Louis Schlesser and Mauro Baldi's C11 had an accident during training. Schlesser and Baldi switched to the replacement vehicle. In the second race in Monza , the team reported two C11s and took the first two places. With the exception of the following championship race at Silverstone , the car won all races that season and Sauber won the constructors' world championship for sports cars in 1990.
Although the Sauber-Mercedes team clinched the overall victory in the 1989 Le Mans 24-hour race with the C9, it decided not to take part this year because the race was not on the racing calendar of the World Sports Car Championship and people were relying on it wanted to focus on winning the world championship.
In 1991, the consumption formula in group C, according to which the engine design is free, but fuel consumption must not exceed 60 l / 100 km, was abolished. Instead, as in Formula 1 , 3.5-liter naturally aspirated engines were prescribed; Racing cars with turbo engines were still allowed, but disadvantaged by various restrictive measures. The C11 was therefore to be replaced by the Mercedes-Benz C291, which was tailored to the changed regulations, but was also used in the first rounds of the 1991 sports car world championship due to problems with its new 180-degree V12 - Mercedes-Benz M 291 . By the time it was completely replaced, the C11 had achieved three more class wins than the new C291.
As the successor to the Sauber C9, the Mercedes-Benz C11 should actually have been called the C10; however, because of the difficult pronunciation of this name, it was decided to skip the ten.
