Brabus has built a four-door convertible while Mercedes finishes preparing its own G-Class cabriolet for production. The 900 Rocket Edition Cabrio, based on the Mercedes-AMG G 63, made its debut at the Monaco Yacht Show with a fabric top, 900 metric horsepower (888 hp) and pricing that pushes past a million euros for German buyers.
Production tops out at 10 examples worldwide, and the export price for the car shown runs €890,740 (about $1,019,000) before German VAT. With tax included, the sticker climbs to €1,059,980 ($1,210,000).
The Key Facts
The engine is a reworked twin-turbo 4.5-liter V8, up from the standard G 63's 4.0-liter unit, built around new forged pistons, connecting rods and a dedicated crankshaft. Output lands at 888 hp and 922 lb-ft of peak torque.
Brabus electronically caps the torque delivered to the wheels at 774 lb-ft, even though the engine can produce more. That still gets the Rocket Cabrio from 0 to 62 mph in 3.7 seconds, with top speed limited to 149 mph.
Brabus says the tire-rated speed cap makes sense on a tall, roofless SUV riding on 24-inch forged Monoblock II wheels, wrapped in 295/30 rubber up front and 345/25 out back. A KW-developed adjustable suspension can drop the body by 1.8 inches.
An exhaust system with switchable valves and four side-exit tips offers a discreet "Coming Home" mode alongside a louder Sport setting. Each car also comes with a blockchain-based digital passport tracking authenticity, ownership history and build specifications.
More Than 500 New Parts
Turning a boxy SUV into an open-top car takes more than removing a roof. Brabus developed over 500 new components for the roof conversion and body reinforcement package, which includes the two-piece electrically operated soft top that opens or closes in 20 seconds and carries a heated glass rear window.
Losing the metal roof costs structural rigidity, so Brabus reinforced the windshield frame and added extra bracing throughout the body. A steel roll bar sits behind the rear doors, wrapped externally in visible carbon fiber to match the body kit.
Every finished car reportedly undergoes more than ten hours of simulated rain testing inside a climate chamber before delivery. The process is meant to prove the fabric top seals as well as a hardtop would in daily use.
This isn't Brabus's first roofless project. The tuner previously built the 1,000-hp Bodo Cabriolet limited to 77 units, and its work now lands alongside the confirmed return of the factory G-Class Cabriolet, previewed by the Mercedes-AMG G63 Cabriolet that is due globally from 2027, with a US launch expected around 2028.
