The four-liter twin-turbo V8 engine of the GT 63 S is uprated by 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 larger compressor unit and modified core assembly with reinforced axial bearing produce a maximum boost pressure of 1.6 bar.
Recalibrating the boost-pressure control and further optimizing the power delivery without impairing the durability required reprogramming the mapping of the electronic engine control unit. To this end, BRABUS conducted extensive testing on stationary engine test benches of the latest generation. At the same time, road testing was conducted on racetracks and in traffic. The new software is introduced into the ECU by the plug-and-play BRABUS PowerXtra auxiliary control unit.
This results in an output increase by 118 kW / 161 hp (158 bhp) and a bump in torque by 100 Nm (74 lb-ft). With a new output of 588 kW / 800 hp (789 bhp) at 6,600 rpm and a peak torque of 1,000 Nm (737 lb-ft) at a low 3,600 rpm, the four-door coupe is one of the most powerful of its kind.
The driving performance speaks for itself: From rest, the BRABUS 800 with SPEEDSHIFT nine-speed sports transmission and 4MATIC+ all-wheel-drive takes just 2.9 seconds to reach 100 km/h (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 315 km/h (196 mph).
BRABUS garnishes the unique high-performance experience with an acoustic treat. 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 millimeters (3.5 in), the BRABUS exhaust system is also an absolute visual delight.
INTERIOR. Maximum variety, Masterful quality.
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 colors and upholstery designs. To complete the interior ambiance, BRABUS can fabricate precious-wood or genuine-carbon inlays in a wide range of colors and specifications.
The BRABUS 800 supercar premiering at the Top Marques Monaco 2019 is fitted with exclusive BRABUS fine leather seats covered with perforated black leather and highlighted with white leather elements. The classy interior captivates not only with its color scheme, but also with its precise white decorative topstitching. Alcantara inserts in the seat side bolsters optimize the lateral support when employing a sporty driving style.
Stainless-steel scuff plates with backlit BRABUS logo that lights up in colors matching the ambient interior lighting round off the high-class interior design. Sporty cockpit features such as BRABUS aluminum door pins and pedals complete the high-performance standard of the BRABUS supercar.
