Just when you think the automotive world has reached peak madness, Brabus decides to cut the roof off a Mercedes-AMG G 63—twice—and turn it into something even more outrageous than the factory ever imagined. Say hello to the Brabus 800 Cabrio and XL 800 Cabrio, two open-air titans built in strictly limited runs of 50 units each, complete with “Masterpiece” interiors and the unmistakable stance of a luxury super-truck.

A G-Class With Its Roof Off? Brabus Says: Why Not.

Brabus didn’t simply unbolt the top. The company “hacked” the G-Class open at the C-pillar and engineered a retractable soft-top roof made from more than 500 newly developed components. It takes 20 seconds to open or close, creating what the tuner calls a “unique open-air experience.”

A carbon-fiber roof bow stabilizes the structure and helps with sound deadening, while a steel roll bar at the rear takes care of safety duties. The result is a convertible SUV that looks equal parts luxury yacht and armored personnel carrier.

Two Flavors of Excess

Both models wear Brabus’s signature widebody treatment and gigantic 24-inch wheels, but their personalities are completely different.

800 Cabrio: The Road Weapon

The standard 800 Cabrio leans toward on-road performance. It rides lower, wears high-performance rubber, and sports exposed carbon elements that make it look something like a convertible G-Class that wants to star in its own music video.

XL 800 Cabrio: Portal-Axle Insanity

The XL 800 Cabrio, though, is the wilder sibling. Thanks to portal axles and a skyscraping 18.9 inches of ground clearance, it isn’t just made to look off-road capable—it genuinely is. Brabus says it’s “mainly designed for phenomenal off-road capabilities,” and with those axles and all-terrain tires, there’s little reason to doubt it.

789 Horsepower of Roof-Down Fury

Under both hoods lives an uprated 4.0-liter twin-turbo V-8 pushing 789 horsepower and 1,000 Nm of torque.

The lighter, road-oriented 800 Cabrio rockets from 0–62 mph in 4.0 seconds and tops out at 150 mph. The taller, knobbier XL version does the sprint in 4.6 seconds, which is absurd given its ground clearance—and even more absurd considering it can likely do that on dirt, sand, gravel, or anything else you point it at.

Open-Air Luxury, the Brabus Way

Inside, both cabs are drenched in Brabus’s so-called “Masterpiece” treatment: ornate leatherwork, bold colors, and enough stitching to upholster a small boutique hotel. The headrests feature neck-level heating to keep passengers warm during winter roof-down cruises—because if you’re spending this much money, you’d better be able to use the thing all year.

Prices That Make a G 63 Look Like a Bargain

If you thought the standard AMG G 63 was already at the top of the food chain, think again.

• The Brabus 800 Cabrio starts at €761,500 (around £670,000 before tax).
• The XL 800 Cabrio begins at €887,600 (around £780,000).

For perspective, a factory G 63 starts from roughly £185,000. That means the Brabus convertibles cost at least £485,000 more—a premium you pay for exclusivity, engineering lunacy, and the sheer joy of driving a roofless super-G that nobody else on your street (or probably your country) will have.
