Unimog 401 with a Westfalia Typ B cab, 1953

Daimler-Benz modified the Unimog for mass production to create the series 2010 and in 1951, started its manufacture in their Gaggenau plant in Baden-Württemberg, where production continued until 2002.

In 1953, the Unimog was updated and the three-pointed Mercedes star began to appear on the bonnet, replacing the Unimog ox horn emblem. The new model became known as the series 401. A new series 402 with a long wheelbase chassis (2,120 mm (83 in) instead of 1,720 mm (68 in)) also became available.

An enclosed driver's cab was available as an option from 1953, making the Unimog a true all-weather vehicle.
