On this episode of Head 2 Head, Jonny Lieberman heads to Graz, Austria, the home of one of the world's toughest off roaders - the Mercedes-Benz G-Wagen. The last time a G63 appeared on Head 2 Head, it beat out the all-new and quite excellent Range Rover Supercharged. This time, however, the G63 faces even stiffer competition — another G63. Of course, this particular G has an extra axle, because it's the $500,000+ G63 AMG 6x6! Costing roughly twice as much as the awesome twin-turbo V-12 powered G65, the 6x6 is the ultimate expression of the Gelandewagen... on paper. But is it actually any good? Is the 6x6 as awesome as it looks, or is the regular G-Wagen just too well thought out? And why is the 6-wheeled truck always jumping in the air like that? Watch and find out!
