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 litres rather than the usual 4.0 litres. This contributes to the boosted output of 888 bhp (662 kilowatts or 900 metric hp) and 774 pound-feet (1,050 Newton-metres) of torque. The stock Mercedes powerplant makes 603 bhp and 627 lb-ft.

Brabus' GLS can hit 62 miles per hour in 3.6 seconds and a top speed as high as 205 mph. In stock form, the Mercedes-AMG GLS63 hits 60 mph in 4.1 seconds and has a top speed of 174 mph.
The engine modifications include increasing the cylinder bore, fitting forged pistons, and upgrading the connecting rods. A billet crankshaft increases the stroke. Brabus fits new turbos with a larger compressor, and their peak boost is 1.4 bar (20.3 psi). High-pressure fuel pumps make sure the powerplant gets enough petrol. The exhaust gasses exit through 75 millimetre (3.0-inch) diameter downpipes.

The company also tweaks the GLS' design. The air intakes have an exposed carbon-fibre finish, and there's a more aggressive front fascia. The SUV rides on 24-inch Monoblock Z wheels in a black colour that matches the vehicle's body. Shadow Grey trim replaces the chrome elements on the standard model.
A custom control module for the air suspension lowers the standard ride height by nearly an inch.
Brabus keeps the dark aesthetic for the interior. A mix of black leather and Alcantara covers the cabin. The trim features a mix of carbon fibre and matte Shadow Grey elements.
If you want a Brabus 900 Superblack, the price starts at the equivalent of €370,550 (£328,000). To compare, a 2023 AMG GLS63 starts at £140,835 in the United Kingdom.
