Brabus CLS V12S
The World's Fastest Four-Door Coupe

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 / 537-kW 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 / 537 kW
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.

Maximum size and state-of-the-art materials characterize the BRABUS high-performance
brake system of the ROCKET. The front axle is fitted with vented ceramics discs in size 375
x 36 mm and 12-piston aluminum fixed calipers. The rear axle features steel discs in size
355 x 28 mm and 6-piston aluminum fixed calipers to round out the powerful and fade-
resistant brake system.

The giant brakes and the enormous performance necessitate the use multi-piece BRABUS
Monoblock S light-alloy wheels with 19-inch diameter. The BRABUS technology partners
Pirelli and Yokohama provide the high-performance tires suitable for these highs speeds.
The optimal tire/wheel combination for the BRABUS ROCKET are 8.5Jx19 wheels in front
with 255/35 ZR 19 tires and 10Jx19 with 285/30 ZR 19 on the rear axle.

The BRABUS designers custom-developed a front apron for the ROCKET with large air
inlets for optimal cooling of oil and water radiators. The shape of the front spoiler and of all
other BRABUS aerodynamic-enhancement parts was fine-tuned in the wind tunnel. Not only
did BRABUS succeed in reducing lift on the front axle, but also in optimizing aerodynamic
drag.

The aerodynamic counterpart to the front spoiler in the rear is the BRABUS rear spoiler lip
which emphasizes the rounded design of the rear. But that's not all: In combination with the
new front apron the spoiler lip reduces aerodynamic lift, thus further improving directional
stability.

Integrated entrance lights are the dominant feature of the BRABUS door sills and the
BRABUS rear apron. Pushing a button on the keyless-entry remote or pulling on a door
handle activates five LED lights on each side and in the rear. They illuminate the ground
behind and on either side of the vehicle to further improve user-friendliness.

The BRABUS rear apron is the perfect backdrop for the four tailpipes of the BRABUS high-
performance exhaust system. Its integrated diffuser also contributes to the refined BRABUS
aerodynamics concept for the ROCKET.

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.
