The C 112 debuted at the Frankfurt Auto Show in 1991 as an experimental prototype and roadgoing version of Mercedes-Benz’s Sauber-built C 11 Group C prototype race car. Its name referenced the well-remembered C 111 prototype series developed in the late 1960s, and like its predecessors, the C 112 utilized the most cutting-edge electronic technologies of the day. It was the first Mercedes-Benz to include active body control that adjusted suspension and chassis positioning as the car was driven. An electronically adjusted spoiler and rear wing, combined with Venturi tunnels molded underneath the car, made the C 112 exceptionally aerodynamic. 

The C 112’s wedge-shaped bodywork referenced that of the earlier C 111 models and defied contemporary trends towards rounded plastic shapes, while its gullwing doors were a nod to the legendary 300 SL. The interior was fully trimmed to offer the driver excellent comfort and advanced safety features. Although nearly 700 orders for the C 112 were placed, Mercedes-Benz ultimately chose not to offer the model for public sale.
