The Unimog 406 is a vehicle from the Unimog series built by Daimler-Benz AG. It was manufactured a total of 37,069 times at the Mercedes-Benz Gaggenau plant between 1963 and 1989. The Unimog 406 is the first series of medium-weight Unimogs. As the first representative of the medium-weight Unimog model family, it had a completely new appearance. Later Unimog series are based in part technically and optically on the Unimog 406.
The Unimog 406 cabrio and closed version
The Unimog 406 came in two forms a closed chassis and en convertible like chassis. Both were equally motorized. The closed version had a 61.9% share in sales while the convertible version took care of 34.4%. The remaining 3.7% was accounted for by other Unimog 406.
In 1965, a model with a long wheelbase was offered for the first time, the Unimog 416. The Unimog 416 was actually a an evolution of the Unimog 406. At 2900 mm, it has the same wheelbase as the long version of the Unimog 404. With engine power ranging ftom 80 too 125 horsepower the Unimog 416 was much stronger than it’s predecessor.
Unimog 403 and Unimog 413
In August 1966, the 406 series was supplemented by the Unimog 403. The Unimog 403 had the OM 314 diesel engine with 54 hp (40 kW) originally intended for the 406 series and was placed in the model range as a cheaper model. With the increasing demand for powerful traction vehicles, Daimler-Benz offered the 403 series from 1969 with 66 hp (48 kW) and from 1972 with 72 hp (53 kW). There is no visual or technical difference between the Unimog 406 and the 403, with the exception of the engine. Since Daimler-Benz also wanted to offer a cheaper version with a long wheelbase, the Unimog 413 was offered in analogy to the 416 from 1969.
