Mercedes-Benz CLK GTR Straßenversion

The Petersen Automotive Museum lists the road-going 6.9-litre CLK GTR at about 612 hp.

For the road car, the racing V12's displacement was increased from 6.0 to about 6.9 litres.

The road-going CLK GTR shared the core suspension architecture of the racing car, while receiving a more civilized interior.

The road-going CLK GTR retained a carbon-fibre monocoque closely related to the racing car's structure.

The rarest production form of the road-going CLK GTR was the roadster, with six examples built.

According to the Petersen Automotive Museum, 28 road-going CLK GTRs were produced: two prototypes, 20 coupés and six roadsters.

The racing CLK GTR won the FIA GT Championship in 1997; during 1998 Mercedes-Benz's program evolved toward the CLK-LM.

GT1 regulations required at least 25 road-going examples to be built for the race car to satisfy homologation requirements.

The CLK GTR was created as the homologation road car for Mercedes-Benz's FIA GT1 program, whose rules required a road-going counterpart to the race car.

At roughly $1.6 million, the CLK GTR was described on introduction as the world's most expensive production car.
