German tuner does some serious engine work on the 12-cylinder unit to deliver 800 PS (588 kW / 788 hp) and 1,420 Nm (1,047 lb-ft) of torque.

German tuner Brabus has introduced the Brabus 800 Coupe, based on the Mercedes-Benz CL 600, at the 2011 Dubai International Motor Show.

The tuner turns the 12-cylinder 5.5 liter unit into one displacing 6.3 liters for a total output of 800 PS (588 kW / 788 hp) and 1,420 Nm (1,047 lb-ft) of torque.

The engine work consists of a new crankshaft with a longer stroke, a larger cylinder bore and larger forged pistons. Brabus also replaces the twin-turbo system with its own for those serious power figures. Transmission is a five-speed automatic.

Top speed has to be electronically-limited to 350 km/h (217-mph) and torque on the car is also electronically governed to 1,100 Nm (811 lb-ft). The 0 to 100 km/h (62 mph) sprint takes just 3.9 seconds and the car reaches 200 km/h (124 mph) in 10.3 seconds.

Brabus adds an aero kit, 21-inch wheels and a lowering module that brings the car 25 mm closer to the ground in order to keep things stable. To reign it all in is Brabus's high-performance brake system.

For the inside is a finish in white leather and black Alcantara with contrasting diamond stitching. Carbon fiber trims, matte surfaces in checkered flag design, aluminum pedals and a sport steering round out the package.
