For the 1990 racing season in Group C, Mercedes-Benz, in cooperation with the Swiss Sauber team. Quite successfully: the team was world champion at the end of the season. This spurred on the engineers at Mercedes-Benz. They were looking to test active dynamic handling systems for large-scale production cars and came up with the high-performance sports car C112. It was powered by a six-liter V12 engine which developed 300 kW (408 hp) and put 580 Newton meters of torque on the crankshaft. The idea was to transfer this performance optimally to the road at the physical limits with the highest level of active safety.
