For most people the Mercedes AMG S63 Coupe – the worlds fastest and most powerful all-wheel-drive coupe – comes with more than enough power in its standard guise and wouldn’t necessarily leave you wanting for more.
This is clearly not the case at tuning company BRABUS, as they have announced that the 2015 Geneva Motor Show will host the world premiere of the BRABUS 850 6.0 Biturbo Coupe.
The new BRABUS 850 6.0 Biturbo Coupe is based on the Mercedes S 63 4MATIC, it has been retuned to produce a whopping 838bhp, a neck breaking 1,450Nm of torque and will reach a top speed of 217mph. The car will launch to 0-62mph in 3.5 seconds, and 0-124mph in just 9.4s, which would make it the world’s fastest all-wheel drive four-seat coupe.
The BRABUS take on the Mercedes coupe retains the 4×4 system found in the standard S63 which controlled via a seven-speed automatic gearbox, though if you have a death wish a rear wheel drive version is optional.
The eight-cylinder twin-turbo engine of the S 63 is thoroughly revised in the BRABUS engine shop using a state-of-the-art machine park. The installation of a special BRABUS crankshaft with longer stroke plus an enlarged cylinder bore and correspondingly larger forged pistons result in a displacement increase from 5,461 cc to 5,912 cc. The flow-optimising fine machining of both cylinder heads also contributes to the performance enhancement.
The two special BRABUS turbochargers with larger compressor units and modified exhaust manifolds that replace the production turbos also play a major part in the enormous increase in power. As part of the engine conversion, special metal catalysts with 75-mm thick down pipes and the BRABUS stainless-steel sports exhaust system with actively controlled butterfly valve are installed in addition.
Other modifications to the production engine are instantly apparent when the hood is opened: one of the key components of the engine conversion is the specially designed BRABUS 850 intake module. It includes a larger air filter housing with enlarged intake cross-section, which is supplied with air via a special duct in the hood, and new carbon-fibre air ducts with significantly enlarged cross-sections. A particularly conspicuous feature is the BRABUS Gold Heat Reflection sheathing of the intake and charge air pipes.
As well as power gains the BRABUS car has been given various aerodynamic-enhancements, which the BRABUS designers developed in the wind tunnel.
A special BRABUS spoiler made from clear-coated carbon fibre was developed for the front bumper. This not only gives the car a more aggressive look but its functional as well as it reduces lift on the front axle at high speeds, further optimizing handling stability.
Adding to the cars aggressive looks are the large air intakes in the front bumper, which have been fitted with tailor-made carbon-fibre
The BRABUS car has also been given a clear-coated BRABUS carbon-fibre diffuser, which is fitted with tailor-made cut-outs for the BRABUS sports exhaust system, and the subtle rear spoiler in the trunk lid (also made from carbon fibre). In addition, the designers developed carbon-fibre surrounds for the side air outlets that add further emphasis to the sporty lines.
Complementing the lines and design of the car are BRABUS Monoblock wheels, which are available for the Mercedes S-Class Coupe with diameters ranging from 18 to 22 inches.
To complement the black paint finish, the interior was refinished in typical BRABUS fashion. The attention to detail is evident in the accents and switches that normally have a silver finish. A total of 219 individual parts were coated in the same Shadow Gold tone as the BRABUS Monoblock F wheels on the vehicle. The headliner was crafted from deep black Alcantara and carbon-fibre touches have been added throughout. And the addition of Aluminium components such as the BRABUS RACE paddle shifters, pedals and door pins finish the interior off.
The BRABUS 850 6.0 Biturbo Coupe is available as a complete car or can also be built on the basis of any existing current Mercedes S 63 Coupe. Prices for this premium tuned Mercedes have yet to be announced, however all will be revealed next week at the Geneva motor show.
