Saab-Scania AB was the name chosen 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 meant that Saab no longer had to import the British Triumph Slant-4 engine, and could instead use the engine production facilities of Scania. In 1972 they started manufacturing 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.
