The SdKfz 4 was developed after the 1941 invasion of the USSR to deal with the ice and mud, which bogged down the road-bound commercial vehicles that were used to supply German forces. It was modified Standard Mercedes-Benz L4500S (4x2) with Horstmann suspension instead of back axle. Another manufacturer of 4.5-t truck, Büssing planned similar conversion of its Büssing-NAG L4500S, but didn't proceeded.
A total of 22,500 Maultier halftracks were produced by 1944, among which 1480 were 4.5-t. SdKfz 4, others — 2-t. SdKfz 3. In 1943 Opel was ordered to build armored vehicles outfitted with 15 cm Panzerwerfer 42 rocket launchers. These vehicles were designated SdKfz 4/1, with around 300 produced. Given the extra weight of the Panzerwerfer, the top speed was only 24 mph (40 kph).
