Mercedes-Benz G 63 AMG 6x6 [View all]

-snip-

The AMG engineers swapped the drivetrain from the G63 AMG, featuring a 5.5-liter, twin-turbo V-8 good for 536 hp, mated to a seven-speed transmission, good enough to hustle the 8,300-lb. juggernaut to 60 mph in about six seconds. Inside, there's room for four passengers to ride in a tableau of luxury, from the quilted white leather seats and carbon-fiber accented dash to the bamboo-lined cargo area.

As for the six wheels, they're not just for show. AMG splits the torque 30/40/30 among the axles from front to rear for maximum traction, with locking differentials for all 37-inch wheels; the 6x6 can ford water more than three feet deep and its 52-degree approach angle means it will climb most anything short of a sheer cliff face. For desert travels, the tires can be inflated and deflated from a panel in the cabin.
