Bibs at the ready. The latest slice of drool-worthy machinery from Brabus has arrived in the form of the 850 6.0 Biturbo Coupe, an 850hp version of the Mercedes S 63 4Matic.
Brabus has made extensive revisions to the S 63’s 5.5-litre V8 engine, the most of drastic of which is increasing the engine displacement to 6 litres and replacing the standard turbochargers with special Brabus variants for an extreme power increase.
A special intake module comprised a larger air filter area, carbon fibre air ducts and gold heat reflection sheathing helps keep things cool. Meanwhile a Brabus stainless-steel exhaust system with 75mm thick down pipes and an active controlled butterfly valve provided the soundtrack.
The Brabus 850 6.0 Biturbo Coupe is capable of producing 850hp from 5,400rpm and 1,069lb/ft (1,450Nm) of torque between 2,500 and 4,500rpm, so there’s never any shortage of head-snapping acceleration – although the torque is electronically limited to 848lb/ft (1,150Nm) to ensure the engine lasts longer than two minutes.
It is entirely possible to blast from 0 to 62mph in 3.5 seconds and from 0 to 124mph in 9.5 seconds, which is impressive given the S 63 is hardly the lightest car. The top speed is restricted to 217mph so the tires don’t rip themselves to shreds, while CO2 emissions are 237g/km.
Aerodynamic revisions do their bit in helping the Brabus cut through the air and look menacing. The clear-coated carbon fibre front spoiler, for instance, reduces lift on the front axle at high speeds for improved stability. Ride height is 15mm lower.
Elsewhere a Brabus carbon fibre diffuser, larger air intakes and 21-inch Brabus Monoblock Platinum Edition alloys add even more presence. The 2015 Geneva Motor Show car (pictured) has Monoblock F cross-spoke variants in a fetching Shadow Gold.
Inside is a beautiful mix of fine black leather and carbon fibre, with the same Shadow Gold colour used for the alloy wheels applied to 219 individual parts inside the car for a touch of class.
Those wanting a slice of this monster can either buy the complete vehicle or apply the upgrade to an existing Mercedes S 63 Coupe for an as yet disclosed price. Expect to dig deep, given the similarly powerful Brabus 850 E63 AMG S 4Matic will set you back €295,618 (£241,000).
Update: The Brabus 850 6.0 Biturbo Coupe starts from €218,239 before tax, rising to €342,288 for a ‘fully equipped car’. An engine conversion costs €69,900 plus €4,900 for installation before tax.
