If there is one vehicle on the road that doesn't need any help attracting attention, it's most certainly the Mercedes G63 AMG 6x6. That hasn't stopped German tuning shops from giving it their own special treatments, though. We got a look at Brabus' 700-hp B63 last year and now Mansory has unleashed a new 829-hp (618 kW) G63 6x6 package.

The 536 horses (400 kW) of the stock G63 AMG 6x6 are nothing to sneeze at, but the beastly Mercedes does have an extra axle when compared to virtually every other utility vehicle on the road or trail, so a little extra horsepower isn't such a bad thing. Mansory doesn't really do things "little", though, so its upgrade is very close to 300 hp (224 kW).

Mansory has reworked the 5.5-liter V8 biturbo, adding a variety of race-grade components, including pistons, connecting rods, big end bearings, crankshaft, crank and cylinder head. It has also redesigned the exhaust system on the way to upping total power to 829 hp. Mansory's engine program is also quite effective at increasing torque, so much so that the tuner has found it necessary to cap it electronically at 738 lb-ft (1,000 Nm). That's an increase from the 560 lb-ft (760 Nm) on the stock G63 six-wheeler.

Mansory has also dressed the G63 6x6 with a bunch of carbon fiber, including a new hood, front skirts, mirror housings and redesigned rear skirt. The new hood includes added venting to cool down the powerful engine. Buyers can choose bare carbon fiber or body color-matched components. The design also includes new LED headlights, LED daytime running lights and high-powered off-road lights mounted to the roof.

Mansory doesn't list pricing, but it won't matter to many people. GT Spirit reported earlier this year that Mercedes had sold out of the G63 6x6 after building somewhere north of 100 models.

Mansory's new package isn't its first crack at the G63 6x6. It previously released a separate 829-hp package with a slightly different look.
