ÖAF

In 1938, when Austria was annexed by the Third Reich, German MAN obtained the majority of shares owned by Fiat in ÖAF, reducing the Italian firm's share to 15%. ÖAF had begun equipping some of its trucks with diesel engines from MAN in 1934.

After the Second World War, the Floridsdorf factory was in the Russian zone and the plants were used for Russian reparations. In 1955, ÖAF was released from these payments and the factory began producing trucks again. They went to Austria to build military trucks but the Austrian army eventually selected rival Steyr for its famous Pinzgauer. Only 136 examples of ÖAF's challenger, the Husar, were built between 1967 and 1969. The ÖAF Tornado was a greater success becoming the best-selling truck in Austria.

In 1970, the company was privatized again; MAN then let it merge with Gräf & Stift, out of which ÖAF Gräf & Stift arose which in 1971 was fully taken over by MAN.

Beginning with the Moskvitch in 1958, ÖAF also acted as Austrian importers of many Russian-made automobiles, including the Lada and the GAZ Volga. In 1982 they also took over the Škoda agency, which they held until 1992 when new owners Volkswagen replaced them. In 1988 they began importing American Chrysler automobiles, but as of July 1993 the company sourced out automotive imports to a new company.
