Mercedes-Benz CLK GTR Roadster

In November of 1998 the very first road-going CLK GTRs were completed. These cars were part of a limited series necessary to homologate the GT1 racecar. GTRs competed in every round of the 1997 FIA GT Championship against the Porsche GT1, BMW LMR and McLaren F1. That season Mercedes dominated, bringing the championship to Mercedes and HWA.
The technology used to beat McLaren on the track is currently bred into the new CLK GTR Roadster. The basis of our roadster is a race-proven, carbon fibre monocoque. Protection for the occupants is provided by an integrated steel roll cage with rigid crash-impact boxes.
A familiar six-liter, Mercedes V12 is the center piece of the roadster. AMG have refined this engine to include an increase in capacity from 6.0 to 6.9 liters. Other key features include an entirely new intake system and revised exhaust headers. The complete system allows the GTR to lash out 610 horsepower to it's rear wheels.

A six-speed transmission is fitted to the power plant. Gear changes are made sequentially by two paddles behind the steering wheel. Behind the GTR Roadster is a wealth of experience attained through motors port practice. Each CLK GTR reflects the successful heritage which includes the 1997 FIA championship. Only five cars will be produced by HWA, the same company which developed and raced the 1997 GTR. With such expertise and exclusivity we can boldly claim the CLK GTR Roadster is one of the greatest modern-day supercars ever offered.
