It rides on a set of massive 37-inch tires and features five differential locks, portal axles, a tire pressure monitoring system and a payload capacity reportedly rated at 1,433 lbs. The biggest difference between the 6x6 and the standard G63 AMG, aside from the extra wheels, is that the springs and dampers have been adjusted in order to accommodate the third axle. The interior, as expected, is decked out in all of the typical G-Wagen luxury flare with leather upholstery and Alcantara trim. Even the rear cargo hold is lined with bamboo. The question now is whether Mercedes will build it.
