In 1932, the Daimler-Benz has developed a powerful 12-ton half-track tractor for the Soviet order, which should be supplied to the Red Army artillery units. But soon the order was canceled, but the achievements of the company roused German army interest, who were actively pursuing a policy of motorized German army.

The base modification Sd.Kfz.8 has chassis with front engine and half-track mover. Behind the driver's cab, which was divided from the rear part by a low partition, were two benches, located across the body, where artillery crew of 9 people took place. There was an awning to protect from rain and snow. A cargo compartment with double-leaf doors in the sides and rear was behind the crew's place.
