Recently Brabus presented their stealth-looking Bullit Coupe 800, which will make its public debut at the Geneva Motor Show. The German tuner fitted a V12 engine into a Mercedes C63 AMG, making it the most powerful C-Class in the world.
In place of the V8 that powers the Mercedes C63 AMG, a twelve-cylinder engine is derived directly from the Brabus E V12. For this purpose an up-to-date Mercedes S 600 engine is completely re-engineered. The displacement of this engine is increased from 5.5 to 6.3 liters 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 exhaust side had to be newly configured as well. This 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 Mercedes C-Class.
All these enhancements resulted in a maximum output of 800 hp (588 kW) at 5,500 rpm, an increase of almost 300 hp over the production engine. The peak torque is 1,420Nm (1,047 lb-ft) from 2,100 rpm, which is electronically limited to 1,100Nm (811 lb-ft). Power is transferred to the rear wheels via a reinforced seven-speed automatic transmission, which is shifted either automatically or manually via shift paddles on the steering wheel, and a limited-slip rear differential with a locking rate of 40 percent. The Bullit Coupe 800 also features driving dynamics systems such as ABS, ASR and ESP.
With this impressive amount of power the Brabus Bullit Coupe 800 ‒ with a curb weight of 1,820 kg (4,012 lbs.) ‒ is able to accelerate to 100km/h (62mph) in 3.7 seconds, while the 200km/h (124 mph) is reached in 9.8 seconds and the 300km/h (186 mph) barrier is hit in 23.8 seconds. The top speed is more than 370 km/h (230 mph).
For stopping power the Bullit Coupe relies on a dual circuit brake system with Brake Assist and a high-performance brake system. This includes 12-piston fixed aluminum calipers with vented and grooved steel discs measuring 380 x 37mm (15.0 x 1.45 in.) at the front, and six-piston fixed aluminum calipers with vented and grooved steel discs measuring 360 x 28mm (14.2 x 1.1 in.) at the rear.
To be able to attain such extreme speeds while maintaining stability, the aerodynamic properties of the two-door car were modified in the wind tunnel. The supplemental carbon-fiber 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 air vents integrated into the front fenders behind the wheel wells.
The designers and engineers at the Brabus headquarters in Bottrop 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 stainless-steel high-performance exhaust system.
The exterior is further enhanced by the new Brabus Monoblock R wheels ‒ sizes 8.5Jx20 in front and 9.5Jx20 on the rear axle ‒ featuring 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. These rims are wrapped in high-performance tires in sizes 235/30 ZR 20 and 275/25 ZR 20 are supplied by Continental, Pirelli or Yokohama.
The height-adjustable coilover suspension was custom developed for the Brabus Bullit Coupe 800 in cooperation with 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 cockpit of the supercar has a distinctly sporty design. The interior was fitted with 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 sport steering wheel as well as aluminum pedals and shifter.
The Brabus Bullit Coupe 800 will sell for an starting at € 378,000, excluding taxes. In Germany this supercar will cost € 449,820. It goes without saying that this car can also be built based on the Black Series C 63 AMG Coupe.
