Eight hundred horsepower, peak torque of 1,000 Nm (737 lb-ft), 2.9 seconds from rest to 62 mph and a top speed of 196 mph make the BRABUS 800 GT 63 S one of the most powerful four-door coupés of its kind.
The Brabus 800 GT 63 S's striking looks are thanks to naked-carbon aerodynamic-enhancement components with sporty styling and hi-tech forged wheels in the new BRABUS Monoblock Z "PLATINUM EDITION" ten-spoke design, featuring an unusual combination of 21 and 22-inch diameter rims for the front and rear axle. The BRABUS 800 based on the Mercedes-AMG GT 63 S 4MATIC+ is a high-performance coupé in a class of its own. BRABUS also refines the interior of the fastback coupe as a matter of course; the company upholstery shop creates exclusive BRABUS fine leather interiors in any desired colour and with a host of sophisticated upholstery designs.
The four-litre twin-turbo V8 engine of the GT 63 S is upgradedby the BRABUS powertrain engineers with the sophisticated BRABUS PowerXtra B40S-800 performance upgrade. The modifications to the engine hardware involve the turbocharging system: Two newly designed BRABUS high-performance turbochargers with a larger compressor unit and modified core assembly with reinforced axial bearing produce a maximum boost pressure of 1.6 bar.
The driving performance speaks for itself: From rest, the BRABUS 800 GT 63 S with SPEEDSHIFT nine-speed sports transmission and 4MATIC+ all-wheel-drive takes just 2.9 seconds to reach 62 mph. The gears can be shifted automatically or manually with the ergonomic BRABUS RACE aluminum paddle shifters on the steering wheel. The top speed is electronically limited to 196 mph.
BRABUS garnishes the unique high-performance experience with a couple of acoustic treats created by two components: BRABUS Boost Xtra, a special adapter for the bypass valve, brings back the "blow-off" noise that used to be typical for turbo engines when the drivers lifts off the gas.
The stainless sport exhaust, which is available for all GT 63 variants and optimizes the power delivery by reducing the exhaust backpressure, offers a variable exhaust note thanks to its integrated actively controlled exhaust flaps. The V8 can be operated in the decidedly subtle "Coming Home" mode or in the "Sport" position, which coaxes an extra powerful V8 sound from the engine. Thanks to its titanium/carbon tailpipes with a diameter of 90 millimetres, the BRABUS exhaust system is also an absolute visual delight.
The face of the Brabus 800 GT 63 S is given an even more striking profile with the combination of BRABUS front spoiler and front fascia attachments for the large air intakes of the bumper. In addition, the spoiler reduces front-axle lift at high speeds, which further improves the handling stability. The rear end of the four-door is also made even sportier: The carbon diffuser insert for the rear fascia perfectly frames the four tailpipes of the BRABUS sport exhaust, whose titanium embellishers were painted black to match the outer skin of the show car for the IAA. Naked-carbon panels at the sides of the rear bumper emphasize the striking lines of the vehicle.
Another important factor in the extravagant BRABUS 800 GT 63 S look is the unusual tire/wheel combination, which the suspension engineers and test drivers of the Bottrop-based company developed specifically for the Mercedes-AMG GT 63. To emphasize the wedge shape of the four-door coupe, the front is fitted with 21-inch wheels while the rear axle sports 22-inch rims. The BRABUS 800 at the IAA 2019 presents the new BRABUS Monoblock Z "PLATINUM EDITION" wheel design. The type designation "Z" stands for an innovative ten-spoke styling. The attractive wheels not only benefit the looks of the BRABUS 800. This king-sized tire/wheel combination also makes the handling even more agile, an effect that can be further amplified with the BRABUS AIRMATIC SPORT Unit. This plug-and-play module is adapted to the air suspension and lowers the ride height of the four-door coupe by about 25 millimetres (1 in) in the two drive modes "Comfort“ and "Sport."
Another special area of expertise of BRABUS is exclusive interior refinement. Under the "BRABUS fine leather" label, the company upholstery shop transforms the finest leather and Alcantara into interiors that satisfy even the most individual requests of any customer. There is a virtually endless variety of available colours and upholstery designs. To complete the interior ambience, BRABUS can fabricate precious-wood or genuine-carbon inlays in a wide range of colours and specifications.
Stainless-steel scuff plates with backlit BRABUS logo that lights up in colours matching the ambient interior lighting round off the high-class interior design. Sporty cockpit features such as BRABUS aluminium door pins and pedals complete the high-performance standard of the BRABUS supercar.
The BRABUS 800 GT 63 S can be ordered as a complete car. Alternatively, BRABUS converts any current Mercedes GT 63 S 4MATIC+ to this performance level all at once or in stages.
