Mercedes-Benz U401 Unimog

The Unimog 401 is an all-wheel-drive vehicle of the Unimog-series by Mercedes-Benz, developed as a tractor and equipment carrier. It was produced by Daimler-Benz in the Unimog plant in Gaggenau from 1953 to 1956. A total of 16,250 Unimog 401 and 402 were made.

Initially, the Unimog 401 was made in the cabrio version only. The closed cab model Froschauge (German for frog-eye), with a cab made by Westfalia-Werke, was introduced in September 1953. An increased wheelbase model was developed, bearing model type 402. Both models were succeeded by the Unimog 411, available in both long and short wheelbases.

After World War II, German engineer Albert Friedrich built the first Universalmotorgerät, however, Daimler-Benz declined to put it into series production. Manufacturer Boehringer in Göppingen on the other hand was interested and produced a prototype for the 1948 DLG-exhibition in Frankfurt. The Unimog attracted much interest, encouraging Boehringer to begin series production. Until 1950, approximately 600 Unimog 70.200 were made; their brand logo was an ox-head with U-shaped horns. In late 1950, Daimler-Benz purchased Boehringer moving Unimog production to Gaggenau, beginning series production in May 1951. Initially, the Unimog’s type number was 2010, changing to 401 in 1953, with the 401 becoming a new type. The Unimog 401 was the first Unimog to receive the Mercedes star on its grille.
