Brabus is very familiar with tuning Mercedes-Benz vehicles after doing it for decades. The modifier's latest offering is the 900 Superblack that turns the Mercedes-AMG GLS63 4Matic into a more powerful performance SUV.
The biggest upgrade involves increasing the twin-turbo engine's displacement to 4.4 liters rather than the usual 4.0 liters. This contributes to the boosted output of 888 horsepower (662 kilowatts or 900 metric hp) and 774 pound-feet (1,050 Newton-meters) of torque. The stock Mercedes powerplant makes 603 hp and 627 lb-ft.
