New Brabus Rocket 900 debuts as a 4-door family hypercoupe


Brabus has created a new ‘Rocket’ out of the Mercedes-AMG GT 63 S 4Matic+ 4-door coupe, limited to just 10 units. This is even more mental than the Brabus 800 we saw last year, which explains the ‘Rocket’ prefix to the 900.

It begins with a more aggressive aerodynamic body kit compared to the 800. The inflated fenders make the 4-door family coupe 78 mm (3.1-inch) wider than the production car. All of the parts of the body kit including the rear wing are made of carbon fibre. The radiator grille hides a carbon ram-air intake system on either side to supply more air to the revised V8 biturbo motor.


Rounding off its exterior looks are forged wheels with carbon aero discs, measuring 21-inch at the front and 22-inch at the rear, shod with Pirelli P Zero high-performance tires. The wheels feature a tastefully applied red pinstripe to compliment the stripes on the front grille.

In addition, the ride height gets lowered by 25 mm in ‘Comfort’ and ‘Sport’ driving modes.

As always, the cabin retains the three-pointed star on the steering wheel, while adding a bit more spice in the form of red accents and red contrast stitching. The seat surfaces and the door cards feature a quilted ‘Crest’ pattern, while the headrests get the Brabus logo. The upper part of the dashboard is covered with Alcantara.


Moving on to the business end of the story, the V8 biturbo motor now displaces 4.4-litres (4,407 cc). Modifications include a special billet crankshaft with longer stroke and larger cylinder bores in combination with matching pistons and rods. The stock turbos are replaced with high-performance ones with a larger compressor unit. A stainless-steel high-performance exhaust system with free-flow metal catalysts and actively controlled exhaust flaps round off the Rocket conversion.

As a result, the engine now pumps out 900 metric hp (662 kW) at 6,200 rpm and a peak torque of 1,250 Nm (922 lb-ft) at 2,900 rpm. In fact, the torque output is electronically limited. A 0-100 km/h (62 mph) acceleration is claimed to be dispatched in 2.8 seconds, while the top speed is electronically limited to 330 km/h (205 mph).

As mentioned, Brabus is making only 10 of these, with each carrying a price tag of €435,800 in Germany (excluding VAT).
