Scania AB is a major Swedish manufacturer of commercial vehicles – specifically heavy trucks and buses. It also manufactures diesel engines for heavy vehicles as well as marine and general industrial applications. Scania AB was formed in 1911 through the merger of Södertälje-based Vabis and Malmö-based Maskinfabriks-aktiebolaget Scania. The company’s head office has been in Södertälje since 1912. In addition to bus and truck engines, Scania’s industrial and marine engines are used in generator sets and in earthmoving and agricultural machinery, as well as on board ships and pleasure crafts.
