Mercedes-Benz reveals the G63 AMG 6×6, a six-wheel-drive luxo SUV

The inevitable has happened.

There are only so many possible permutations of a metal box on four wheels designed to go fast over any terrain, and from the Jeep Wrangler to the Range Rover, all of them have been explored in some degree with varying levels of ability and luxury. It was only a matter of time before a group of mad engineers gathered together and said "Screw it, let's go six-wheel-drive."

Those engineers work for Mercedes-Benz, and this creation, the G63 AMG 6x6, isn't a concept, but a luxury SUV that the German automaker will build for a handful of wealthy customers.

Six-wheel-drive trucks have been in military and commercial use for decades; Mercedes made a few for use before World War II, and its commercial division has supplied a 6x6 version of the old Gelandewagen to Austrian forces since 2011.
