It is a medium-sized vehicle bigger than the traditional Unimog 411, but smaller than the Unimog 406. Introduction of new heavy models and Unimog 411 production ceasing in the mid-1970s changed the Unimog 421's role in the Unimog lineup; it became the predecessor of the light Unimog series and thus succeeded the Unimog 411.
