The Mercedes-Benz CLK GTR (W297) is a sports car and race car produced by AMG, at that time the performance and motorsports partner of Mercedes-Benz (and now a subsidiary of Mercedes-Benz).
Intended for racing in the new FIA GT Championship series in 1997, the CLK GTR was designed primarily as a race car, with the road cars necessary in order to meet homologation standards being secondary in the car's design.
After conquering the FIA GT Championship, Mercedes-Benz set its sights on competing at the 24 Hours of Le Mans in 1998 after their departure in 1991. However, Le Mans presented a different challenge from what was offered in the FIA GT, in that the race distances were nearly one tenth the distance covered at Le Mans. Therefore, Mercedes-AMG set about to modify the CLK GTR in order to meet the new demands required at Le Mans.
