The German tuning firm has just announced that it is has taken the existing 5.5-litre twin-turbo V8 and increased its displacement to just shy of 6.0-litres. It has also added its own turbochargers with larger compressor units and bespoke exhaust manifolds.
The result is a vehicle that produces just shy of 850bhp and a staggering 1,450Nm of torque, although that figure has been pared back to 1,150Nm in order to protect the powertrain from eating itself after a few savage sessions around the circuit. Performance figures are equally ridiculous, especially when you consider it features four seats and weighs almost two-tonnes. The 0-62mph sprint complete in just 3.5 seconds and the top speed limited to a massively illegal 217mph. That's almost enough to put Ferrari's upcoming 488 GTB to shame.
To reduce lift at high speeds, a bespoke clear-coated carbon fibre spoiler has been added to the rear, while the suspension has been dropped to its very lowest setting and massive 21-inch forged alloys added. Brabus has confirmed that customers will be able to specify their own colour schemes, although a price for arguably the world's fastest all-wheel-drive four-seat coupe has yet to be confirmed.
