The record

The 1974 redesign gave the Unimog a new cab and the heavy 425/435 chassis; the U 1300 L became the Bundeswehr’s two-tonne truck (some 20,000) and the 437 series carried the range from 1988 to 2013 with turbocharged engines and up to 240 hp. Gaggenau built them until 2002 and Wörth after; the 437.4 UHN of 2002 replaced them for the military and expedition market.

AI rendering impression

An AI rendering impression starts from a 3D model of this vehicle, which an image model then paints into a scene. It is an artist's impression of the type, made to give a feel for the vehicle in its element — not a photograph, and not a record of any particular vehicle.

Proportions, fittings, markings, colours and the setting can all drift from the original in the process. For the vehicle's actual details, rely on the specification, the photographs and the cited sources on this page.
