The CLK DTM AMG was given a five-speed speedshift paddle-actuated transmission, upgraded suspension, wider performance tires, and ceramic-composite front brakes. A carbon-fiber composite was used on the hood, doors, and other areas of the exterior, which featured flared wheel arches, a deep front valance, and rear wing. The interior was given one-piece carbon fiber bucket seats and drilled alloy pedals. Power was supplied from a 5.4-litre M113 engine offering 582 horsepower and 590 lbs-ft of torque. Pistons, crankcase, valve gear, cooling system, intake ducting, supercharger, and exhaust were all revised, and the engine reportedly delivers 86% of its peak torque from only 2,000 RPM. Zero-to-sixty mph was accomplished in 3.9 seconds with the top speed electronically limited to 199 mph.
