SAAB Sonetts were built in Trollhattan, Sweden from 1966 to 1974. The first model the Sonett II, used a two-cycle, three-cylinder, three carburetor Monte Carlo engine. In 1968, with the introduction of emission standards, the two-stroke, always smoking, enigne was replaced with a V-4 cylinder, four-cycle, engine already used in some German and British Ford automobiles. This model, the Sonett II V-4 was similar in design to the Sonett II except for the distinctive bulge on the bonnet to clear the new Solex downdraft carburetors. Total production for the Sonett II from late 1967 to 1969 was 1,610 cars.

The engine is a 1498cc V-4 cylinder developing 73 hp.
