Brabus announced the 900 Rocket Edition Cabrio on September 22, a convertible built from the Mercedes-AMG G 63 and limited to 10 cars worldwide. Its for-sale listing on October 7 priced one at €1,020,275 with Germany’s 19% value-added tax, or €857,374 without it, at the factory in Bottrop.
The engine is Brabus’s enlarged twin-turbo V8. Brabus rates it at 662 kW at 6,200 rpm, which it quotes as 900 hp, and 1,250 Nm, or 922 lb-ft, at 2,900 rpm, limited electronically to 1,050 Nm in the car. The Cabrio reaches 100 km/h, or 62 mph, in a claimed 3.7 seconds and is the first open-top car to carry the Rocket name.
Key Takeaways

- Output is 662 kW and 1,250 Nm, which Brabus quotes as 900 metric hp and 922 lb-ft. By the U.S. measure 662 kW is 888 hp, and torque is limited to 1,050 Nm in the car.
- The soft top opens or closes in 20 seconds and uses more than 500 components made for the conversion.
- Top speed is limited to 240 km/h, or 149 mph, which Brabus says protects the tires.
- The Cabrio costs €342,130 more than the Rocket Edition hardtop on Brabus’s price list.
A Two-Piece Soft Top With More Than 500 Parts
Brabus says the two-piece fabric roof keeps the G-Class outline. It uses more than 500 components made for the conversion and opens or closes in 20 seconds. The rear window is heated safety glass, and when closed the roof locks into a reinforced windshield frame. A carbon-fiber bow in the front section holds the roof’s shape at speed, and Brabus credits it with lowering cabin noise.
Behind the rear doors, a steel roll bar that Brabus calls the C-BOW is built into the modified body and trimmed in bare carbon fiber. The rear part of the roof folds away behind the back seats, under a fitted tonneau cover.
Brabus says every Cabrio spends more than ten hours under continuous water in a climate chamber before delivery, as a test of the roof and its seals.
An inverted “77” is woven into the fabric above the rear window, for the year the company was founded.
The V8 Grows From 3,982 to 4,407 cc
Brabus builds the engine in Bottrop from the G 63’s 4.0-liter V8. Enlarged cylinder bores of 84 millimeters, forged pistons and a billet crankshaft with a 100-millimeter stroke take displacement to 4,407 cubic centimeters, which Brabus calls 4.5 liters. Two larger turbochargers produce up to 1.4 bar of boost.
Brabus puts the gain at 231 kW, or 315 metric hp, over the standard G 63. The exhaust has 76-millimeter downpipes and exits ahead of each rear wheel, with valves the driver can switch between a Sport setting and a quieter one named Coming Home.

The Rear Wheels Are 24 Inches Tall and 12 Wide

Inside, black leather and Alcantara are quilted in a pattern Brabus calls Shell, across the seats, door panels, footwells and luggage compartment. Switches, vents, speaker grilles and door-lock pins are finished in red.
