Ultra-powerful, ultrafast and conspicuously inconspicuous: the Brabus Bullit
Coupe 800, which celebrates its world debut at the 2012 Geneva Motor Show, is
built in small-series production based on the two-door Mercedes C63 AMG model.
In place of the 6.3-liter fast-revving V8 that powers the production car, a
twelve-cylinder engine in Brabus 800 V12 Biturbo specification lurks beneath the
matte-black exterior. 800 hp (588 kW) and a peak torque of 1,047 lb-ft (1,420
Nm) propel the Bullit Coupe 800 to superlative performance: 3.6 seconds to 60
mph, 23.8 seconds from 0 - 186 mph (300 km/h) and a top speed in excess of 230
mph (370 km/h) document the unique know-how of the engineers from Brabus.
Brabus went into the wind tunnel to engineer the aerodynamic-enhancement
components that are part of the equipment of this supercar, as are new 20-inch
Brabus Monoblock R wheels, a sport suspension with customer-selectable ride
height and damper rates, a high-performance brake system and exclusive cockpit
design.
The supercar will sell for an MSRP starting at 378,000 EUR ($500,000). It goes
without saying that this car can also be built based on the Black Series C63 AMG
Coupe.
Brabus 800 V12 Biturbo Engine
Numerous modifications to the reinforced C-Class body were necessary to implant
the turbocharged V12 into the engine bay. The Brabus 800 V12 Biturbo engine is
derived directly from the Brabus E V12 one of ten. For this purpose an
up-to-date Mercedes S600 engine Motor is completely reengineered in the company
engine building shop.
There is nothing to take the place of displacement except more displacement and
for that reason displacement of the 12-cylinder, three-valve engine is increased
from 5.5 to 6.3 liters (336 to 384 cu. in.) with the help of a special
crankshaft with longer stroke, larger, forged pistons and an increase in
cylinder bore across the board. Intake and outlet ports of both cylinder heads
are optimized for mixture flow, and fitted with sports camshafts.
The engine peripherals were also completely reworked completely. The inlet side
features a newly designed, larger header casing that gets its combustion air
from carbon-fiber ram-air intake system integrated into the hood.
To achieve the desired power increase of almost 300 hp over the production
engine, the exhaust side had to be newly configured as well. The Brabus 800
Biturbo system comprises two special exhaust manifolds with integrated
high-performance turbochargers, and four water-to-air intercoolers. The
stainless-steel high-performance exhaust system with free-flow metal catalysts
and driver-controlled butterfly valve also was created specifically for the
C-Class Coupe floorpan.
State-of-the-art engine Brabus test benches were used by the engineers for
designing new mapping for engine electronics and on-board diagnostics. The
result is maximum power yield while meeting strict current EURO V emission
standards. The Brabus 800 V12 Biturbo high-capacity engine produces 800 hp (588
kW) at 5,500 rpm. The peak torque of 1,047 lb-ft (1,420 Nm) is limited
electronically in the car to 811 lb-ft (1,100 Nm).
Power is transferred to the rear wheels via an appropriately reinforced
seven-speed automatic transmission, which is shifted either automatically or
manually via shift paddles on the steering wheel, and a Brabus limited-slip rear
differential with a locking rate of 40 percent. The Brabus Bullit Coupe 800
features all state-of-the-art driving dynamics systems such as ABS, ASR and ESP.
Aerodynamics
To be able to attain such extreme speeds while maintaining outstanding
directional stability, the aerodynamic properties of the two-door car were
modified extensively in the wind tunnel. The supplemental carbon-fiber Brabus
front spoiler reduces lift on the front axle at high speeds. The carbon-fiber
lightweight air routers for the air inlets in the front fascia go beyond
optimizing the supply of cooling air for radiators and front brakes. These
lateral air vents also allow the air streaming through the radiators to exit
again as quickly as possible. Another significant contribution to the heat
exchange in the engine bay is made by the Brabus air vents integrated into the
front fenders behind the wheel wells.
The Brabus designers have developed an aerodynamically effective combination of
rear wing and diffuser insert for the rear fascia in order to generate more
downforce on the rear axle. This carbon-fiber component has cutouts on the right
and left side for the dual ceramics-plated design tailpipes of the Brabus
stainless-steel high-performance exhaust system.
Brabus Monoblock R Wheels
The thrilling looks of the Brabus Bullit Coupe 800 is rounded out by the new
Brabus Monoblock R wheels. They represent a fresh approach with their unique
design that features two times five double spokes arranged on two different
plains. While the posterior plain has a titanium paint finish, the anterior
surfaces are polished and coated with a smoke-colored clear lacquer, which lends
the wheel a highly individual character. In sizes 8.5Jx20 in front and 9.5Jx20
on the rear axle the Brabus Monoblock R wheels make perfect use of the available
space in the wheel wells. The high-performance tires in sizes 235/30 ZR 20 and
275/25 ZR 20 are supplied by technology partners Continental, Pirelli or
YOKOHAMA.
Suspension and Brakes
The height-adjustable coilover suspension was custom developed for the Brabus
Bullit Coupe 800 in cooperation with technology partner BILSTEIN. It features
gas-pressure shocks on front and rear axle with ten selectable settings each for
bound and rebound for a sporty yet comfortable ride. Sport sway bars reduce body
roll during fast cornering to a minimum.
The Brabus high-performance brake system consists of vented and grooved steel
brake discs that measure 380 x 37 millimeters (15.0 x 1.45 in.) and 12-piston
aluminum fixed calipers in the front. In combination with vented and grooved
steel discs measuring 360 x 28 millimeters (14.2 x 1.1 in.) and six-piston fixed
aluminum calipers on the rear axle it easily masters even highest brake loads.
Customized Interior
The cockpit of the supercar has a distinctly sporty design. The interior was
clad by the Brabus master craftsmen in the upholstery shop in a combination of
black leather and Alcantara to match the outer skin. Red contrasting seams add
discrete sporty highlights. This look is rounded out by genuine carbon-fiber
components on the dashboard, center console and door trim. Further sporty
features are the ergonomically shaped Brabus sport steering wheel as well as
aluminum pedals and shifter.
