Although the front profile of the CLK-GTR retains some resemblance with their conventional CLK, it is not the usual CLK but a highly advanced pure racing version. The monocoque is made of carbon fiber composite and reinforced by integrated steel roll cage. The 5,987cm V12 engine, producing more than 600 horsepower output, is bolted directly to the monocoque and works as a load-carrying element. The tremendous power is delivered to the rear wheels via a transversely mounted, six speed sequential transmission. The four wheel double wishbone suspension system is connected to the multiply-adjustable gas pressure shock absorbers via pull-rods and rocker arms to provide optimum road holding performance. Front and rear wheels are fitted with wide racing slicks, and dual-circuit brake system with internally ventilated brake discs provide positive stopping power.
