Brabus 900 Mean Green

German tuning house Brabus has revealed one of the most extreme versions of the Mercedes-AMG GLS 63, the Brabus 900 Mean Green. This luxury SUV boasts serious engine upgrades, aggressive styling, and a price comparable to a Rolls-Royce Cullinan.

The base is the Mercedes-AMG GLS63 4Matic, while the package includes a grille with the Brabus logo, 24-inch Monoblock ZV alloy wheels, a carbon fiber aerodynamic package (front spoiler, sills, rear diffuser...), modified suspension (the car is 25 mm lower), stronger brakes, a Brabus exhaust system, as well as interior changes (Mean Green leather and Alcantara, carbon fiber...). Under the hood is a twin-turbo V8 engine with 662 kW/900 HP and 1250 Nm (although electrically limited to 1050 Nm), so acceleration to 100 km/h takes 3.6 seconds, while the top speed is 310 km/h.

The project is based on the Mercedes-AMG GLS 63, which in its standard version is equipped with a 4.0-liter twin-turbo V8 producing 603 horsepower. Brabus engineers increased the engine's displacement to 4.5 liters, installing a new crankshaft, reinforced connecting rods, forged pistons, and updated turbochargers.

With this, the power jumps to 900 horsepower, while the torque reaches 1,250 Nm, electronically limited to 1,050 Nm. Acceleration from 0 to 100 km/h takes only 3.6 seconds, and the top speed reaches 310 km/h.

Externally, the Brabus 900 Mean Green stands out with a carbon fiber aerodynamic kit, a new splitter, diffuser, and spoiler. The vehicle features the characteristic Mean Green paint and 24-inch Monoblock ZV forged wheels. The interior has also been completely redesigned.

The cabin is upholstered in green leather and Alcantara, complemented by carbon fiber inserts, new pedals, and characteristic Brabus decorative elements.

Priced at around €509,000, the Brabus 900 Mean Green ranks among the most expensive tuned SUVs on the market. To put this in context, a similar amount could buy a new Rolls-Royce Cullinan.

Brabus has long been known for transforming luxury Mercedes models into extreme machines. However, the Brabus 900 Mean Green demonstrates just how far tuning can go, combining supercar power with ultra-luxury pricing.

Thus, one might think that the three-pointed star brand is now looking to pull the plug on it and replace it with an entirely new model, right? Wrong, because the Mercedes GLS is here to stay, and the automaker is now preparing yet another facelift for it, which is currently in the making, and will bring it the star-studded makeover, in addition to other novelties inside and out, and probably beneath the skin, too.

Mercedes offers the GLS in several versions in the United States of America. The Benz family comprises the 450 and 580 models, priced from $90,250 and $116,150, respectively, The former uses a mild-hybrid 3.0-liter inline-six turbocharged engine with 375 hp and 369 lb-ft (500 Nm) of torque, and hits 60 mph (97 kph) in 5.8 seconds. The latter packs a mild-hybrid 4.0L bi-turbo V8 unit, rated at 510 hp and 538 lb-ft (730 Nm), and is 1.1 seconds faster.

Maybach has also had its way with the GLS. The model is called the Mercedes-Maybach GLS 600, and wants to take a swing at the Bentley Bentayga and the Rolls-Royce Cullinan. It has 550 hp and 568 lb-ft (770 Nm) of torque on tap from its 4.0L bi-turbo V8, hits 60 mph in 4.6 seconds, which makes it a mere one-tenth of a second faster than the Mercedes-Benz GLS 580, and has an MSRP of $180,000 attached to it.

As for the most agile member of the family, it is none other than the Mercedes-AMG GLS 63. It hits 60 mph in 4.1 seconds, has 603 hp and 627 lb-ft (850 Nm) of torque, and starts at $151,050 for the 2026 model year in the States. 

For one, the engine’s displacement has been increased to 4.5 liters and the famous tuner mentions stuff such as the precisely-balanced special crankshaft, the new connecting rods, forged pistons, turbochargers, downpipes, and a few other bits and bobs. The result? A cool 900 metric horsepower available at 6,200 rpm. The output translates to 887 brake horsepower and 662 kilowatts. Available at 2,900 rpm, the peak thrust is 922 pound-feet (1,250 Nm), and it was electronically limited to 774 lb-ft (1,050 Nm).
