During the Second World War Scania-Vabis’ entire production went to the Swedish Armed Forces and other public institutions.

Unfortunately, production was in several cases started without adequate testing and those first postwar trucks suffered quality problems that cost Scania-Vabis both money and reputation to repair.

In early 1950 there were also a small number of the four-wheel drive F40 built, before that model disappeared because of low market demand.

In the spring of 1953 the final development of Scania-Vabis’ module engines were introduced, with larger displacement.
