The new BRABUS 800 Coupe is based on the latest Mercedes-Benz CL 600 BRABUS. The 12-cylinder engine of the CL 600 is reengineered thoroughly in the BRABUS engine-building shop that is equipped with state-of-the-art machine tools. Displacement is increased from 5.5 to 6.3 liters (336 to 384 cu. in.) with the help of a special BRABUS crankshaft with longer stroke, larger cylinder bore and correspondingly larger forged pistons. Further performance-enhancing modifications to the engine itself are the fine-machining of the two cylinder heads for optimized mixture flow and the installation of four special camshafts.

The engine peripherals are modified extensively as well: the standard twin-turbo system is replaced with a high-end turbocharging system designed by the BRABUS engine specialists. The new system features two custom exhaust manifolds with integrated turbine housings and high-performance turbochargers as well as four water-to-air intercoolers. The combustion air is supplied by a carbon-fiber ram-air intake integrated into the hood. In addition there is a stainless-steel high-performance exhaust system with free-flow metal catalysts.
