Background
Following the 1955 Le Mans disaster, Mercedes-Benz had withdrawn its factory-backed race team from all motorsport activities.[9] It was not until 1985 that Mercedes reintroduced itself to motorsport, entering the 1985 World Sportscar Championship. Starting off as an engine supplier to Sauber, this partnership bloomed into a full-time factory-backed effort. Despite Mercedes winning the World Sportscar Championship twice in 1989 and 1990, they eventually withdrew at the end of 1991 following disappointing results.[10]
However, Mercedes saw success elsewhere, with a burgeoning touring car program in the Deutsche Tourenwagen Meisterschaft, where the 190 E and its Evolution I and II siblings were climbing up the ranks. The 1991 season would see the 190 E Evo II take the honours in the constructors' championship. Klaus Ludwig piloted the car to the 1992 drivers' championship, with the 190 E being replaced by the W202 C-Class following the conclusion of the 1993 season. The C-Class went on to dominate both drivers and constructors championships from 1994 to 1996; as a result of the domination the Deutsche Tourenwagen Meisterschaft/International Touring Car Championship folded in late 1996, with both remaining competitors Opel and Alfa Romeo withdrawing due to the rising costs.[11][12][13]
Without a top series to compete in, Mercedes-Benz looked towards the BPR Global GT Series, which had recently become an FIA-sanctioned championship, the FIA GT Championship, where Mercedes-Benz saw an opportunity to go against manufacturers such as Porsche and McLaren.[8][14] The McLaren F1 GTR was the dominant car in this series, and in order to defeat it fellow German marque Porsche built a dedicated racecar,[15] the 911 GT1. It became the first of the manufacturer's "homologation specials", with Norbert Singer modifying a Porsche 962 chassis to accommodate the front fascia of a Porsche 993, leaving other things such as the suspension and engine largely intact.[16][17]
The CLK GTR was developed in a mere 128 days, this development time hastened by the purchase of McLaren F1 GTR chassis #11R from then-reigning FIA GT Championship champions Larbre Compétition. The car served as AMG's mule, the F1's bodywork was replaced by AMG's own, and the BMW S70 engine replaced by Mercedes' own powerplant, a M120 V12.[22][23] The car was eventually restored to its original mechanical condition, and was auctioned off in Monaco in 2000 by RM Sotheby's.[24][23][25]
