Saab were Swedish aircraft manufacturers and when World War 2 was over, in order to retain their skilled staff branched out into making cars, much as Bristol, Messerschmitt and Heinkel did. The cars had 2 stroke transverse mounted engines with front wheel drive. The first of the production was the Saab 92, being continually evolved with the addition of an external boot opening. The Saab 93 introduced in 1955 had a 3 cylinder engine but still a 2 stroke conventionally mounted, and by the time the 2 stroke was dropped for a Ford Taunus engine the Saab 96 was born, with more than double the horsepower. The Saab 99 of 1968 was all new, now overhead cam Triumph engined which was produced up to 1984.
