When it comes to modifying luxury SUVs, few do it better than Brabus. This legendary German tuner has been specializing in Mercedes-Benz vehicles for decades, and these days loves to build insanely overpowered versions of stock Mercedes-AMG and Maybach cars. Brabus doesn't just stick to the luxury stuff: a lot of its creations are more than capable of handling some serious off-roading, but nothing it has built comes close to offering the capability and thrills of this. Brabus calls it the 900 Crawler, and the final result is nothing like the G-Class it bears resemblance to. It might look like a modified Mercedes-Benz G-Class, but it's a fully-custom machine that isn't even road-legal. Strap in and take a deep breath, because this thing is nuts, and that's on a scale of insane Brabus creations.

For its 45th anniversary, Brabus decided to build the ultimate luxury off-road machine. The Brabus 900 Crawler is the company's first ground-up in-house developed vehicle, and features a fully custom chassis and tubular frame. The exterior features notable highlights such as that massive vented hood, underbody skid plates, LED headlights, and a fifth wheel mounted on the back.

The 900 Crawler is powered by the "Brabus Rocket 900" power plant, which is essentially a Mercedes-AMG twin-turbo V8 used in various AMG applications including the Mercedes-AMG G63. It starts out as a 4.0-liter V8 before Brabus bores it out to 4.5 liters, fits stronger pistons, a billet crankshaft, and two large turbos boosting 1.4 bar to produce a monumental 888 brake horsepower and 922 lb-ft of torque. That tremendous amount of power is channeled to all four wheels via a nine-speed automatic transmission. A 26.4-gallon fuel cell and a series of high-pressure fuel pumps keeps this beast fed. An electronically-adjustable exhaust system with three-inch downpipes makes the Crawler sound like it wants to destroy the human race.

Under all the carbon fiber bodywork, the Crawler hides a set of portal axles, height-adjustable struts with four-way adjustable damping. The exterior is simply a few carbon-Kevlar body panels fastened to a steel safety cell, and it looks badass. The Crawler rolls on a set of 20-inch Brabus Monoblock HD Platinum Edition forged wheels with 40-inch tires.

The performance figures are as impressive as styling: ground clearance is pegged at 20.9 inches with 6.3 inches of spring travel, the curb weight is a reasonable 4,553 lbs, and the Crawler will hit 62 mph in only 3.4 seconds. Due to the off-road tires, Brabus has limited its top speed to just under 100 mph.

Inside the cabin you'll find four SilverTex-upholstered bucket seats, an intercom system, and a GPS-based off-road navigation system. Only 15 of these crazy machines will be built in 2022, with another ten following in 2023 and 2024. The price you ask? A cool €749,000 ($791,038). A Ford Bronco Raptor has nothing on this.
