It's the ultimate sleeper! Brabus' matte-black stealth coupe has no outward pizzazz whatsoever (at least to the untrained eye), but with a 788 bhp twin-turbo V12 under the hood, it can hit 100 km/h in 3.7 seconds, 200 km/h in 9.8 seconds, 300 km/h (186 mph) in 23.8 seconds on its way to a top speed of more than 370 km/h (230 mph).

The two-door coupe is loosley based on the Mercedes-Benz C 63 AMG Coupe, though the 6.3-liter fast-revving V8 that powers the production car has been replaced with a BRABUS 800 V12 Biturbo, which is essentially a Mercedes S 600 engine reengineered to produce an additional 300 bhp.

UPGRADE

The 6.233 liter (380 ci) alloy V12 uses a three-valve combustion chamber, and is capable of delivering a Bugatti-like 1,420 Nm (1,047 lb-ft) of torque. For the longevity of the drivetrain and tyres, plus the drivability of the vehicle, this is electronically limited to 1,100 Nm (811 lb-ft) from 2100 rpm upwards, providing a long flat, preposterously muscular torque delivery. This car will provide an acceleration experience like few others in existence.

The reinforced seven-speed automatic transmission can be shifted either automatically or manually via shift paddles on the steering wheel, and the car also has a BRABUS limited-slip rear differential with a locking rate of 40 percent plus all the state-of-the-art driving dynamics systems such as ABS, ASR and ESP.

The supercar will sell for EUR 378,000 - half a million United States dollars. Where does all the money go? Watch for the full story when we get near the car in Geneva.
