Since some customers prefer a car that is both super strong and extra-large, BRABUS decided to focus on Mercedes-Benz’s GLS-Class top model which is the GLS 63 4MATIC. This has resulted in a supercar that best symbolizes BRABUS and is called the BRABUS 850 XL. Powering it is the eight-cylinder twin-turbo engine with displacement increased by six liters.
Maximum output is at 838 bhp (625 kW/850 HP) with peak torque of 1,069 lb.-ft. (1,450 Nm). In terms of power, this is higher by 261bhp (195 kW/265 HP) when compared to the engine in the previous model. Acceleration from zero to 62 mph (100 km/h) is possible in 4.2 seconds despite having a weight of 2.6 tons.
However to ensure safety, its maximum speed has been electronically limited to 186 mph (200 km/h). With the power output possible at 5,400 rpm and toque coming in from 2,500 rpm and up to 4,500 rpm, its performance is indeed closer to a full-blown sports car.
For those may not want to spend that much, BRABUS is offering owners of GLS 63 4MATIC two upgrades with the first an increase to 622 bhp (464 kW/630 HP) and the second at 690 bhp (515 kW/700 HP). With this amount of performance, it made it necessary to make some changes to the chassis, tires, and even aerodynamics.
