There are some drive tests where we would love to have automated voice and sound transcription technology to be able to capture for you the thrills in real time. Don't let this plain ol' four-wheeled box fool you; the new Mercedes-Benz G63 AMG is so full of character it's fit to burst. You would not be chastised for staring at the exterior of the G63 and noticing nothing different from the 2012 Geländewagen. The changes outside are just a few and deliberately so; redesigning this icon is just as sensitive an issue as redesigning a Porsche 911 for those rabidly enamored of the old school image. To be brief -- there are now turn indicators in the side-view mirrors, LED running lights, and on this new AMG model, the bumper and twin-blade grille are different from those on lesser trims.
