Universalmotorgerät – Mercedes Benz Unimog 406

As it became apparent that the Allies were going to win the Second World War ideas were sort about what to do with Germany after hostilities ceased. In 1944 United States Secretary of the Treasury Henry Morgenthau, Jr came up with the Morgenthau Plan which sort to split Germany into three sectors with a vision of a deindustrialised, pastoral agrarian nation. It soon became apparent however that such a plan would only be able to support 2/3rds of the German population meaning around 25 million Germans would have to be re-located.

To give the vehicles additional ground clearance the axles were fitted with four wheels of equal size and portal gears so that the axle centers were above the wheel centers. The original track width was devised so that the vehicle could stand astride two rows of potatoes in a field. Many of these features can still be found on Unimogs leaving the factory today.
