The Mercedes Unimog U20 features a cab over engine configuration which gives it pretty compact exterior dimensions and a spacious interior.

To be protected against corrosion, the cab received a galvanized treatment which guarantees protection in water, snow and at low temperatures.

The tall cabin comes with a raked windscreen which is combined with a “V” shaped radiator grille that bares the three pointed star in its center. The turning signals are placed at the base of the cab and sit on top of the big rectangular headlights.

In order to be able to tackle the most savage terrains, the Unimog U20 has a high ground clearance which is combined with massive wheels making the truck look like a T-Rex on wheels.

With its width of only 2.15 m and a height of 2.7 m, the Unimog U20 can squeeze even through the narrowest streets and is a joy to be driven around the city.
