During the war, Steyr-Daimler-Puch built vehicles like the Raupenschlepper, Ost for the German Wehrmacht armed forces, and afterwards, modified Fiat automobiles for Austrian consumption, adding swing axles and, in some models, engines of their own design.[1] These were the "Steyr-Fiat" 1100 Mod E, followed by the 1400, which from 1953 got an Austrian 2-liter engine, and was named Steyr 2000. The production of Steyr automobiles was finally terminated in 1959, when it was replaced by the Fiat 1800/2100 six-cylinder models.
