Saab-Scania AB was the name taken when truck and bus manufacturer Scania-Vabis of Södertälje merged with car and aeroplane manufacturer Saab AB of Trollhättan in 1968, under the Wallenberg family group of companies. The merger led to the advance that Saab no longer had to import the British Triumph Slant-4 engine, but could use the engine making facilities of Scania so, in 1972 they started manufacturing there for the 2.0 L B version. In 1977, Saab took advantage of Scania's experience with turbochargers and added one to the engine, thus creating one of the earliest turbocharged automobile engines to be produced in large numbers.
