Brabus presents the V12 Biturbo Bullit Mercedes C-Class - 720hp and 1100Nm

Pegged as the ‘ultimate wolf in sheep’s clothing,’ Mercedes tuner Brabus has unveiled its new V12 Biturbo C-Class sedan that it plans to present at tomorrow’s Frankfurt Motor Show. Brabus has been transplanting high output, large displacement engines into regular sedans for the past three decades, which has led it to develop the new Bullit C-Class sedan powered by a 720hp (537kW) 6.3L V12.

The mega-engine develops a peak torque of 1,320Nm (974 lb-ft) but has to be electronically limited to 1,100Nm (811 lb-ft) to preserve the gearbox and tires. In developing the new powerplant, engineers at Brabus added special pistons and connecting rods, a new turbocharging system with two larger chargers and more efficient intercoolers, and metal catalysts with a low back pressure stainless-steel exhaust.

Power is transferred to the rear wheels via a massively modified five-speed automatic transmission and a Brabus rear locking differential with a locking rate of up to 40%. The car sprints from 0–100km/h (62mph) in just 3.9 seconds, reaches 200km/h (124mph) after just 10.49 seconds and passes the 300km/h (186mph) mark after a mere 24.5 seconds. Top speed is claimed to be in excess of 360km/h (224mph).

The car also gets its own custom suspension and brake package, designed to accommodate the power and weight of the twin-turbo V12 engine. Engineers installed a height-adjustable coil-over suspension set-up and sport sway bars to improve handling. The brake package consists of monster 12-piston aluminum fixed calipers gripping vented and grooved 380mm discs up front, and six-piston units biting 360mm discs in the rear.
