In the world of Mercedes AMGs, nothing is more ostentatious or belligerently amazing as the Geländewagen. Its boxy shape that hasn’t changed since WWII signals money like nobody’s business, and a penchant for dubbing them out. However, while here in the States we get the G63 version, with its paltry 5.5L twin-turbo V8 making 544 horsepower, the rest of the world can have the V12 version that makes a grand spectacle at 612 horsepower.
