Making a world premiere at the 2013 International Motor Show in Frankfurt, Germany, BRABUS kicked off its new B63S, featuring 700 horsepower for six wheels – two wheels more than normal, plus power in abundance, is the norm for BRABUS.

The BRABUS B63S is an exclusive and powerful off-roader based on the new Mercedes G 63 AMG 6×6 with a 5.5-liter V-8 twin-turbo with BRABUS B63S – 700 engine tuning producing 700 hp (690 bhp). This six-wheel-drive beast weighing in at around four tons can jump from zero to 100 km/h (62 mph) in just 7.4 seconds. Its top speed is limited electronically to 160 km/h (100 mph) due to the 37-inch off-road tires.

The Mercedes G 63 AMG 6×6 is a small-run production vehicle with a 5.5-liter V-8 four-valve Biturbo engine producing 400 kW/544 hp (536 bhp). The BRABUS B63S – 700 performance kit, which is also available for all other current Mercedes-Benz 63 AMG SUVs, unleashes the inherent power slumbering in the turbocharged V-8 engine. The production turbochargers are replaced by two special BRABUS turbochargers with larger compressor units, which produce a higher boost pressure. BRABUS Gold Heat Reflection sheathing for the intake and charge-air pipes further lower the charge-air temperature. 

In addition, special high-performance metal catalysts with 75-mm (2.9 in.) downpipes are installed to lower the back pressure. The stainless-steel sport exhaust system with controlled butterfly valve was custom-developed for the G 63 6×6 AMG and offers both optimized power yield and active control of the exhaust note. Drivers can select at the push of a button between the subtle “Coming Home” mode and a markedly potent exhaust note in the “Sport” position.

The BRABUS engine also delivers a much heftier torque: between 2,000 rpm and 4,500 rpm the engine sends a massive 960 Nm (708 lb-ft) of torque instead of the standard 760 Nm (561 lb-ft) to the AMG SpeedShift Plus 7G-Tronic automatic transmission. This is complemented by special BRABUS aluminum shift paddles that facilitate manual gearshifts from the multifunction steering wheel of the G-Class.

Another focus of the BRABUS refinement for the mightiest G model ever is in the cockpit. Its fiery red Mastik leather/Alcantara interior is in striking contrast to the black, chrome and carbon-fiber BRABUS exterior. The company upholstery shop meticulously crafted an exclusive BRABUS fine leather ambiance from a combination of fiery red and black leather and Alcantara.

Of course, the BRABUS 636 is not the off-road vehicle for everyone. But who wouldn’t want to ‘wheel this beast through the Rubicon, on the red rock slopes of Moab, or the deep woods of Michigan? Off Road Xtreme wonders how it would go tire-to-tire, right out of the box, with a whole bunch of other rigs? What do you think?
