Renowned German tuning house Brabus has once again pushed the boundaries of automotive excess, transforming the Mercedes-AMG G 63 (W465) into an ultra-exclusive, open-top supercar. Dubbed the Brabus 900 Rocket Edition Cabrio, this new release marks a historic milestone as the first-ever open-top model to wear the prestigious Brabus Rocket badge.
With production strictly limited to just 10 units globally, this million-dollar machine pairs the rugged silhouette of a traditional off-roader with jaw-dropping, track-ready performance.
Engineering an Open-Top Supercar
Creating a stable convertible out of a heavy, boxy luxury SUV is no small feat. To achieve this without sacrificing structural integrity, Brabus developed a complex, electrically operated two-piece soft-top system comprising over 500 newly engineered components.
When closed, the roof locks seamlessly into a heavily reinforced windshield frame, supported by an integrated carbon-fiber roof bow designed to withstand high speeds. Additionally, a custom “C-BOW” steel roll bar clad in exposed carbon fiber has been integrated right behind the rear doors to protect structural rigidity. Each completed vehicle undergoes exhaustive weatherproofing trials, including more than 10 hours of simulated downpours in a specialized climate chamber.
Earth-Shattering Performance
Underneath the full-carbon hood lies a heavily modified powerplant. Brabus has bored out the standard AMG 4.0-liter V8, expanding its displacement to 4.5 liters and equipping it with custom forged pistons, a precision-balanced billet crankshaft, and larger high-performance turbochargers.
The result is a staggering 900 horsepower and an electronically limited 1,250 Nm of torque. Mated to a nine-speed automatic transmission and an all-wheel-drive system, this open-air behemoth rockets from 0 to 100 km/h in just 3.7 seconds, with its top speed electronically capped at 240 km/h to protect the ultra-wide tires.
An active stainless-steel high-performance exhaust system with valve control allows drivers to alternate between a subtle “Coming Home” whisper and an aggressive, thunderous V8 roar at the push of a button.
Unmistakable Styling and Bespoke Interiors
Visually, the Rocket Edition Cabrio commands attention with a widebody WIDESTAR kit, exposed carbon-fiber aerodynamic elements, and massive 24-inch Monoblock II EVO “Platinum Edition” forged wheels featuring carbon aero-blades.
Inside, the cabin showcases Brabus’s signature “Masterpiece” craftsmanship. It features supreme black fine leather and Alcantara upholstery detailed with intricate shell-pattern quilting, contrasting “Rocket Red” stitching, and matching matte red interior trim pieces. Practicality meets cutting-edge tech via a blockchain-based Digital Product Passport integrated into the trunk, offering verified, tamper-proof records of the vehicle’s authenticity and ownership history.
With a price tag nearing €1 million before taxes, the Brabus 900 Rocket Edition Cabrio is built exclusively for collectors looking for the ultimate intersection of unbridled power, rare exclusivity, and open-air luxury.
