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 C 63 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 (788 bhp) / 588 kW and a peak torque of 1,420 Nm (1,047 lb-ft) propel the BULLIT Coupe 800 to superlative performance: 3.7 seconds to 100 km/h (62 mph), 23.8 seconds from 0 – 300 km/h (186 mph) and a top speed in excess of 370 km/h (230 mph) 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 EUR 378,000. It goes without saying that this car can also be built based on the Black Series C 63 AMG Coupe.
2012 Brabus Bullit Coupe 800: Performance
The BRABUS BULLIT Coupe 800 seamlessly continues the tradition of high-performance supercars from Bottrop. Following in the footsteps of the BRABUS BULLIT supercars based on the Mercedes C-Class sedan, which each produced 730 hp (720 bhp) / 537 kW and reached top speeds in excess of 360 km/h (224 mph), the even more powerful BRABUS BULLIT Coupe 800 has now been developed based on the new C-Class Coupe.
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 S 600 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, which like all BRABUS high-performance engines is lubricated exclusively with MOTUL synthetic motor oil, produces 800 PS (788 bhp) / 588 kW at 5,500 rpm. The peak torque of 1,420 Nm (1,047 lb-ft) is limited electronically in the car to 1,100 Nm (811 lb-ft).
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.
The matte-black stealth coupe delivers unrivaled performance: in a catapult start just 3.7 seconds pass from 0-100 km/h (62 mph), 9.8 seconds to 200 km/h (124 mph). The 300-km/h (186-mph) barrier is shattered after 23.8 seconds. Top speed is more than 370 km/h (230 mph).
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.
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.
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.
2012 Brabus Bullit Coupe 800: Design
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.
