Stuttgart. The Silver Arrows shine once more: When the FIA GT Championship was founded in 1997 as the successor to the BPR Global GT Series, Mercedes-Benz competed with the new CLK-GTR racing touring car. The vehicle was developed, built and ultimately used in the championship together with motorsport partner AMG.
The CLK-GTR with the silhouette of the production Mercedes-Benz CLK (C 208) was created in an extremely short space of time: AMG was tasked with building the vehicle on 5 December 1996, the first test of the V12 engine on the test bench already took place on 21 December. Two days after that, AMG commissioned the monocoque made of a laminate of carbon fibre and Kevlar. The first vehicle was completed on 26 March 1997 with the first test drives on the Spanish Circuito del Jarama racetrack near Madrid conducted by Bernd Schneider, the later world champion, taking place two days later.
In addition to Schneider (1995 DTM champion), the drivers for the 1997 season also included Klaus Ludwig (1992 and 1994 DTM champion). The two extremely successful touring car experts duelled for the championship. On 11 May 1997, Schneider and Alexander Wurz finished in second place at the British Empire Trophy on the Silverstone Circuit (Great Britain). On 29 June, Schneider and Ludwig won the 4-hour Nürburgring race ahead of their team mates Alessandro Nannini and Marcel Tiemann.
Schneider now had the championship firmly in his sights: He finished second in Spa-Francorchamps in Belgium (20 July 1997, with Wurz) and won in Spielberg in Austria (3 August 1997, with Ludwig and Bernd Mayländer ahead of a second CLK-GTR driven by Nannini and Tiemann), in Suzuka in Japan (24 August 1997, with Nannini and Tiemann ahead of Ludwig and Mayländer), in the 4-hour race at Donington, Great Britain (14 September 1997 with Wurz, ahead of Nannini and Tiemann), and finally the two US races in Sebring (19 October 1997, with Ludwig) and Laguna Seca (26 October 1997, with Ludwig). It was the second championship for Bernd Schneider with Mercedes-Benz. Four more titles in the DTM were to follow – in the years 2000, 2001, 2003 and 2006.
AMG Mercedes initially continued to use the CLK-GTR in the second season of the FIA GT Championship before the team switched to the CLK-LM. This race car was developed for the 24-Hours of Le Mans and was powered by a V8 engine instead of the V12. Klaus Ludwig won the FIA GT Championship in that season.
Race car for demanding private customers
A special feature of the mid-engine race car with its V12 engine of type GT 122 (5986 cc displacement) rated at 464 kW (631 hp) is its design as a production race car. According to the FIA (Fédération Internationale de l’Automobile) regulations, the car also had to be built as a production vehicle at a minimum quantity. As a result, 25 vehicles of the highly exclusive street-legal CLK-GTR (C 297) were built. However, the buyers of this 320-km/h super sports car did not get the engine of the race car derived from the M 120 with dry-sump lubrication and other optimizations such as titanium connecting rods and valves. Instead, the production vehicle was equipped with a 6.9-litre V12 series engine of type M 120 rated at 450 kW (612 hp).
