Lately German tuner Brabus has been dropping hints about a big debut at the Geneva Motor Show. Now they have taken the wraps off the highly anticipated model, which is a new 850 model based on the Mercedes S-Class 63 AMG Coupe, Brabus Mercedes S63 Coupe for short.

Being an 850 means Brabus Mercedes S63 Coupe is powered by the firm’s celebrated V12 twin-turbo engine. This unit comes with exquisite features such as Gold Heat Reflection sheathing of the intake and charge air pipes, bespoke intakes and exhaust pipes, and a pretty beefy software for the ECU. It needs a special lubricant made by MOTUL which makes maintenance outside Europe a bit tricky. But for all its prissiness, this engine returns a huge of power: 625 kW / 850 horsepower (838 bhp) and 1,450 Nm (1,069 lb-ft), electronically limited to 1,150 Nm (848 lb-ft).

Performance-wise, and thanks to a custom seven-speed dual-clutch transmission and Brabus-tuned 4MATIC all-wheel-drive, Brabus S63 850 catapults from 0 to 100 km/h (62 mph) in just 3.5 seconds after just 9.4 seconds it passes 200 km/h. Top speed is limited electronically to 350 km/h (217 mph).

Brabus Mercedes S63 Coupe also comes with a pretty awesome body kit featuring custom bumpers, vented bonnet, flared wheel arches, side skirts and side vents, rear bumper with diffuser and tail spoiler. The highlight of the Geneva-bound car is a set of Monoblock “PLATINUM EDITION” 21-inch forged wheels in Shadow Gold Chrome with rubber in sizes 255/35 ZR 21 for the front and 295/30 ZR 21 for the rear axle.

Inside you find the usual dose of leather and carbon fiber, plus 219 individual parts coated in the same Shadow Gold as the wheels. It’s a nice touch, since Brabus interiors were all starting to look the same.
