Do you like your trucks supersized and be just downright powerful? Yes, there are several out there that fit the bill. But with the Mercedes-Benz Unimog, you're looking at the granddaddy of them all. Mercedes-Benz's premier line of four-wheel drive trucks is still as strapping as ever sixty years after it first debuted. The latest version of the Unimog is now Euro VI-compliant, which ups its already superb utility of the Unimog by several notches. Other notable enhancements include the revamped panoramic cab, brand-new hydraulics and work systems, and an impressive synergetic traction drive (which significantly improves the vehicle's efficiency).
