The Sauber C11 was a dominant Group C endurance racer built by Sauber Motorsport with factory support from Mercedes-Benz. Introduced for the 1990 season of the World Sportscar Championship, it used a twin-turbocharged 5.0-liter Mercedes M119 V8 producing around 700 horsepower in race trim. The carbon-fiber prototype was extremely efficient aerodynamically and brutally fast on long straights, helping Sauber-Mercedes win the 1990 teams’ championship while drivers Jean-Louis Schlesser and Mauro Baldi secured the drivers’ title. It remains one of the most successful and recognizable late-era Group C machines, bridging the gap before Mercedes moved fully into Formula One in the early 1990s.
