The world's fastest four-door coupe comes from Brabus and celebrates its world premiere at the Frankfurt Motor Show IAA 2005 in Frankfurt/Main. This automobile, built in small-series production based on the Mercedes CLS model series, is powered by a 730-hp 6.3-liter twelve-cylinder twin-turbo engine, that was implanted with almost surgical precision into the engine bay of the four-door. The performance speaks for itself: 0 – 100 km/h in 4.0 seconds, 0 – 200 km/h in 10.5 seconds, 0 – 300 km/h in 29.5 seconds are just as unique as is the electronically limited top speed of 350 km/h.
At the heart of this new high-performance automobile lies the V12 twin-turbo engine from the SL 600. Brabus fits the engine with a special crankshaft, increases the cylinder bore and installs forged pistons, resulting in a displacement increase to 6,233 ccm. Further modifications include the optimization of the mixture flow in the intake and outlet manifolds of both cylinder heads as well as the installation of sport camshafts.
In addition the Brabus powerplant engineers equip the engine with custom-developed larger turbochargers, more efficient intercoolers and a stainless-steel high-performance exhaust system with low back pressure metal catalysts and four tailpipes. Newly programmed engine electronics coordinate all new components perfectly and contribute not only to maximum power yield but also to meeting all current legal emission limits.
After the engine conversion, now also available for all Mercedes-Benz 600 und 65 models with twin-turbo V12, the Brabus S V12 S Biturbo engine becomes the most powerful TÜV-tested engine from Germany: The engines puts out its maximum power of 730 hp at 5,100 rpm. Peak torque is 1,320 Nm, limited electronically to 1,100 Nm, available from a low 2,100 rpm. Power is transferred to the rear wheels via a modified five-speed automatic transmission and the Brabus locking differential. The Brabus Rocket engine and the entire drivetrain is operated with high-performance lubricants from technology partner Aral.
Naturally it is essential that the unique performance the world's fastest four-door coupe is capable of can be safely controlled at all times. To do so Brabus has developed two special suspensions for the Rocket: The comfort version features air suspension with automatic ride leveling. The sport version comes with a height-adjustable coil-over suspension and gas-pressure shocks with six different settings for bound and rebound on front and rear axle.
The interior of the Brabus Rocket also meets the highest expectations of the distinguishing customers of one of the world's most exclusive automobiles. Soft and breathable Brabus Mastik leather and Alcantara are part of the exclusive Brabus ambiance as is the ergonomically shaped Brabus sport steering wheel and the speedometer with 360-km/h scale.
