Rare Brabus Rocket 900 on Mercedes-AMG GT 63 S hits the market

Brabus Rocket 900 just proved again that top-shelf tuning isn’t always about seven-figure price tags. In Germany, one of the tuning house’s rarest projects has surfaced for sale: a Rocket 900 built on the Mercedes-AMG GT 63 S 4-Door Coupe. The car is essentially brand-new—delivery mileage only—already complete with the full package of upgrades.

The focus here is the engineering. The stock 4.0-liter V8 has been reworked into a 4.5-liter twin-turbo with new turbochargers, a retuned ECU, and an exhaust with active valves capped by carbon-titanium tips. The result is 900 metric horsepower, 1,250 Nm of torque, and peak pull available from 2,900 rpm. On paper, it’s a specification that makes the Rocket badge feel fully earned.

Visually, it wears Obsidian Black paint and a carbon package: splitter, grille elements, diffuser, and wider arches. The car sits on Monoblock Z Platinum Edition wheels with a red accent line, paired with a suspension-lowering module. Inside, leather with grey stitching and Alcantara set the tone, complemented by carbon accents.

The real headline is the asking price. Hollmann is asking 329,500 euros (about $387,000 at the current exchange rate)—a substantial sum, yet notably below the usual seven‑digit expectations. With only 10 units produced, it reads as a rare chance to secure a Rocket 900 in near-new condition.
