In 1970 Canadian firm Bombardier Transportation acquired a controlling share in the company and renamed it Bombardier-Rotax GmbH.

Jacob Lohner transformed his father's craft business into a factory eventually manufacturing between 300 and 500 vehicles per year.

Porsche later developed petrol-engined cars with electric transmissions, some versions of which had additional batteries.

Vehicles using the petrol electric transmission with hub motors were sold to the German army and to the Viennese fire brigade.

The plant was damaged in 1944, and post World War II the company was in public administration until 1949 when it was returned to the control of the Lohner family.

During the 1960s contracts included hay-loaders, gun carriages for the Austrian Army, and Bombardier Ski-Doos which were produced under license from 1966 to 1970.

[note 2] As of 2012 the company operates as Bombardier Transportation Austria GmbH & Co. KG, and manufactures trams.
