With a 577-hp biturbo V8 powering a 0-60 mph (96.5 km/h) time of just 3.9 seconds, the Mercedes S63 AMG 4Matic Coupe isn't exactly a slouch. Or at least it didn't seem that way before German tuner Brabus turned it into an out-and-out power-n-speed machine. The S63-based Brabus 850 6.0 Biturbo Coupe bolts to 62 mph in 3.5 seconds and doesn't stop accelerating until the needle hits 217 mph (350 km/h).

The existence of the Bugatti Veyron, twilight years or not, makes Brabus' claim of the "world's fastest and most powerful all-wheel-drive coupe" a blatant and rather silly misstatement. It's particularly silly because the car is cool enough on its own; it doesn't need untrue hyperbole.

It may not be the king of AWD coupes, but Brabus puts its tuned S63 into the royal family by boosting displacement from 5.5 liters to 5.9 liters, which it rounds up to "6.0" by way of a specially designed crankshaft, larger cylinder bore and enlarged forged pistons. From there, Brabus replaces Mercedes' turbos with a pair of its own, adds its own intake module and Gold Heat Reflection sheathing, remaps the injection and ignition, and routes exhaust through a stainless steel sport system with actively controlled butterfly valve. All that wrenching boosts output by more than 260 hp, giving the tuner car the 850 hp (838 bhp/625 kW) designation it wears in its name. The tuned sports car has the capability of twisting out a heady 1,069 lb-ft (1,450 Nm) of torque between 2,500 and 4,500 rpm, but Brabus puts the cap at 848 lb-ft (1,150 Nm) to protect the lifespan of the powertrain.

All that output gets channeled to all four wheels through a combination of a seven-speed paddle-shift automatic transmission and stock 4Matic all-wheel drive. Those that prefer the purity of rear-wheel drive sports car can select that option upon order.

An aerodynamics kit helps the 850 make full use of its super-potent powertrain. The kit includes a carbon fiber front spoiler, carbon-trimmed front bumper intakes, a carbon fiber rear diffuser and a subtle carbon trunk lid spoiler.

After hitting 62 mph in 3.5 seconds, the super-2+2 goes on to hit 124 mph (200 km/h) in 9.4 seconds. The 217-mph electronic limit is there to prevent damage to the high-performance tires that wrap the 21-in Brabus Monoblock "Platinum Edition" forged wheels. Brabus offers Continental, Yokohama and Pirelli tire options in sizes 255/35 ZR 21 up front and 295/30 ZR 21 out back. It also offers a variety of other 18- to 22-in wheel/tire combinations.

The interior matches the blacked-out body with black Mastik leather and copper-colored stitching and piping. Brabus has replaced the traditional silver finish on a total of 219 components, opting for a Shadow Gold finish that ties into the forged wheels. The interior also gets a deep-black Alcantara headliner, carbon fiber trim in place of wood inlays, aluminum components and a Brabus speedometer that's marked up to 400 km/h (250 mph). A set of backlit "Brabus 850" scuff plates ensure that you never forget what car you're in, and the backlighting, along with the ambient interior lighting, can be ordered in the buyer's choice of color.

Brabus will prepare the 850 6.0 Biturbo Coupe as a complete vehicle or convert the customer's own S63 Coupe. It doesn't mention how much those options cost, but given the Mercedes S63 AMG Coupe's $162K base price, it really doesn't matter for most of the world's population.

The new Brabus will make its world debut at next week's Geneva Motor Show. Gizmag will be there to get plenty of photos and more info.
