 Mercedes-Benz C291

The Mercedes-Benz C291 was a sports-prototype racing car introduced for the 1991 World Sportscar Championship season.The 1991 season marked the introduction of the FIA’s new, and controversial, 3.5 litre formula which replaced the highly successful Group C category that had been used in the World Sportscar Championship since 1982, though due to a small number of entries for the 3.5 litre formula heavily penalised Group C cars (which were subject to weight penalties and started behind the new-style C1 entries on the grid) were allowed participate in the season's C2 category.
