Some cars are built to hug the road, carving through hairpin corners and propelling their drivers down tree-lined back roads—while others are built for the exact opposite. For those looking to conquer any terrain in opulent luxury, the 2014 Mercedes-Benz G 63 AMG 6x6 Brabus B63S-700 is just the machine. One of approximately 100 examples produced and powered by a Brabus-upgraded 5.5-liter AMG V8 making 700 horsepower, this stunning Designo Mystic Blue example will be offered at Broad Arrow's upcoming Amelia Concours Auction, 6 – 7 March.
At its launch, the Mercedes-Benz G 63 AMG 6x6 was boldly described as “the most spectacular cross-country vehicle of all time.” It fused the uncompromising performance ethos of AMG with more than four decades of Geländewagen off-road capability. This experience comes from both civilian and military applications, delivering exceptional comfort while remaining capable of conquering virtually any terrain or climate. Once back on the tarmac, AMG muscle transforms this extreme machine. It offers surprising versatility and an impressive on-road pace despite weighing an impressive four-and-a-half tons.

Standing over seven feet tall, nearly seven feet wide, and almost 20 feet long—over three and a half feet longer than a standard G-Class—giving the 6x6 a commanding presence. Built on Mercedes-Benz's proven military modular platform, the G 63 AMG 6x6 is the first civilian model from the marque to use the innovative portal axles. By raising the axle centerline, ground clearance increases by nearly half a meter. Power is routed through five locking differentials and all six wheels, with a 30:40:30 torque split. Each axle features independent suspension, providing excellent wheel articulation and surface grip, even in tough terrain. The closely spaced rear axles—just 1,100 mm apart—work with Öhlins bypass shock absorbers to further enhance control.
An onboard tire inflation system allows cabin-mounted pressure adjustment at the touch of a button, independently controlling the front and rear axles. Supported by beadlock wheels, a high-capacity air pump, and four 20-liter air tanks, the system can reinflate tires from as little as 0.5 bar for sand driving to the recommended 1.8 bar for road use in approximately 20 seconds—dramatically quicker than conventional setups.
Fitting any luxurious Mercedes, this European-market 6x6's amenities include a Harman Kardon premium audio system with COMAND and navigation, dual-zone climate control, and four individually adjustable, heated, and cooled bucket seats. Before leaving Germany to join its first owner's collection in Dubai, the 6x6 was sent to Bottrop where Brabus thoroughly upgraded it to their formidable B63S–700 specification, as noted on its Manufacturer's Certificate from Brabus. This included installing a custom-designed ECU, larger turbochargers, new intake air pipes with gold heat shielding, an additional air-to-water intercooler, high-performance catalytic converters with 75 mm, lower-resistance stainless-steel downpipes, and butterfly valves to route the exhaust through the side pipes when desired. These upgrades increased horsepower by 23 percent, bringing the total to an impressive 700. Additional vents have been added to the hood and the tops of the fenders to help keep this potent V8 running cool.

While at Brabus, the interior was retrimmed with black Brabus fine leather with a hex-grid pattern contrasting red stitching. The pattern continues through the door panels, with the center console and steering wheel using the same black leather and red stitching. The black leather headrests prominently display the vehicle's unique attributes with the Brabus “B” logo in red stitching. The interior is completed with carbon fiber trim on the center console and a black Alcantara headliner. The wheels were upgraded to black Hutchinson beadlock wheels and Brabus center caps and are currently shod with 37 by 13.5-inch BFGoodrich Mud-Terrain T/A KM2 tires. The exterior of the car also received additional LED lighting, Brabus badging on the rear, a red G700 badge in the grill, and a “B” in place of the Mercedes logo throughout the car.
With this example likely being the most unique of any 6x6 produced, it only deepens the allure of what many consider "the most spectacular cross-country vehicle of all time."
