Borgward was tasked to design a 3 ton towing vehicle. The prototype was ready in 1933 but it only had a 72 HP engine and four road-wheels per side. The second prototype wasn’t any better so in 1938 the project was given to Hanomag. The company added two more road- wheels per side, changed the transmission and gave it a 100 HP engine. The demand was so great that 5 more companies were added to the production of the Sd.Kfz.11. Between 1937 and 1945 25,000 vehicles were produced in 5 variants.
