Brabus turns the Mercedes-AMG G63 into a 900-hp pickup truck

Brabus has turned the Mercedes-AMG G63 into a pickup truck, and it calls the result the P900 Rocket Edition. The German tuner took the G-wagen's 4.0-liter V-8, bored it out to 4.5 liters, and lifted output from 577 horsepower to exactly 900 hp.

Peak torque climbs to 922 pound-feet, though Brabus says it is electronically capped at 774 pound-feet to protect the drivetrain. The truck reaches 62 mph in 3.7 seconds, seven-tenths quicker than Mercedes claims for the stock G63, and it tops out at 149 mph.

That top speed matches what the standard SUV-shaped G63 is limited to with an optional performance package. Brabus is best known for turning already extravagant Mercedes models into more ostentatious machines, and this build extends that formula into a new silhouette.

The pickup body is the obvious departure. Brabus has built truck versions of the G-wagen before, but this one adds the company's usual widened bodywork and cosmetic aggression to a bed that gives the truck an unmistakable, squared-off profile.

No buyer is expected to haul lumber or load a couch into the back. For the Brabus customer making an impression on the streets of Los Angeles, Miami or elsewhere, the bed is about presence, not practicality, and it now ranks only behind the art deco Bodo coupe in the company's catalog.

Brabus is a Bottrop-based tuner whose cars begin as Mercedes models and leave with more power, wider arches and a six-figure price tag layered on top. The G63 donor is already one of the most audacious vehicles available new from a dealership, and Brabus is selling owners something even more so.

The 4.5-liter displacement is a meaningful change from the factory 4.0-liter unit, not a software tune. Brabus pairs the larger engine with the same nine-speed automatic that carries the standard G63, and the figures it quotes are manufacturer claims rather than independent test results.

What the power figures change

The P900 Rocket Edition is 323 horsepower stronger than the G63 Mercedes sells, and the 900-hp figure places it among the most powerful Brabus builds to date, though the company has gone further on other models. The 0-62 mph time is the headline, and it beats the factory truck by seven-tenths of a second.

Brabus has not published a price for the P900 Rocket Edition, has not said how many it will build, and has offered no production timeline for the first deliveries. That silence is normal for the tuner's one-off commissions, where each truck is configured to a buyer's specification and the cost runs well into the hundreds of thousands of euros.

What the company has disclosed is the engineering restraint. Leaving 148 pound-feet of the engine's torque on the table is unusual for a tuner marketing a 900-hp figure, and it tells buyers the drivetrain, not the engine, is now the limiting part.

Brabus has spent decades as Mercedes' most aggressive aftermarket partner, and its name carries weight among collectors who want a G-wagen that cannot be mistaken for a showroom car. The pickup body is the latest escalation in a range built on exclusivity rather than utility.

Our own coverage of garage has long tracked the electric pickup market, where trucks like the Rivian R1T and Ford F-150 Lightning lead the charge. The P900 Rocket Edition is on the opposite end of that equation: a gasoline V-8 with no hybrid assistance and no pretense of efficiency.

When we last wrote about Mercedes-AMG it was the electric GT63 SUV and its 1,153 hp, a sign that the performance arm is pushing toward battery power. The Brabus truck is a reminder that the G63's old-school V-8 still has a devoted audience willing to pay for more of it.

Brabus's pickups follow a tradition that dates to the manufacturer's earliest conversions of the G-class in the 1980s and 1990s. This is not the first time the company has cut a G-wagen into a truck, but it is the most powerful one it has offered in that shape.

The Mercedes-Benz G-class itself has carried the same ladder frame and boxy cab since 1979, and its continued success is why Brabus keeps returning to it. The tuner's page on our site catalogues Brabus cars and their technical specifications alongside the history of the brand.

The company has confirmed the specifications it published but has offered no production timeline, a familiar pattern for a build designed around individual commissions.
