Spied! Mercedes G-Class Prototype Sports G63 AMG 6x6 Parts

AMG is working on what could be the Goldilocks of the G-Wagen family -- a model that's more extreme than the standard G-Class but not as radical as the completely-bonkers, half-million-dollar G63 6x6. Spy photographers captured a four-wheeled G-Class riding higher than stock, and sporting a many of the 6x6's unique components.

The prototype wears different side skirts, a revised rear bumper, and wider fender flares compared to a standard G-Class. But most importantly, the test mule appears to be equipped with the same hardcore portal axles used on the 6x6. Those heavy-duty bits are usually found on Unimogs and Hummer H1s, and are what make the 6x6 model so expensive. The 6x6's portal axles are unique in that they allow a top speed of up to 100 mph, as opposed to around 65 mph on the Unimog. Even with the differentials locked, the 6x6 can do 50 mph. We've heard that the axles were originally developed for an unnamed country's military, and AMG decided to put them to work on the G63 6x6 to help offset the development cost. If those parts are now going to a (presumably cheaper) four-wheeled model, AMG could spread out the cost even further.

The wider fenders likely accommodate a wider track and wider wheels. This tester doesn't feature the 6x6's beadlock wheels, and also doesn't have the 20-pound air tanks in the rear fenders, which probably means it doesn't have the 6x6's central tire inflation/deflation system. Expect this special G-Class to sport the same 536-hp twin-turbo 5.5-liter V-8 as the 6x6 when it debuts, possibly as early as next year.
