The Sauber C12 was the car with which the Sauber F1 team made its FIA Formula One World Championship debut in 1993.
The V10 Sauber 2175A built by Ilmor in affiliation with Mercedes. The Sauber branding was given the prominence of “Concept by Mercedes-Benz” decals on the engine cowling and the two parties’ close relationship from their World Sportscar Championship program.
The C12 achieved a points total of 12 and 7th place in the Constructors’ World Championship standings. It was replaced at the start of the 1994 season by the Sauber C13.
