The Saab 99 is an automobile was produced from 1968 to 1984.
The first engine used in the original 99 was a four-cylinder in-line engine that was tilted at 45 degrees, basically half of a V8. The 1709 cc Triumph-sourced engine produced 87 PS (64 kW; 86 hp) at 5500 rpm. The engine was water-cooled, but unlike most cars of the time it had an electric cooling fan. Triumph soon upgraded the engine to 1.85L: the appearance in February 1971 of the 4-door Saab 99 (99CM4 series) coincided with the adoption of the bored out 1854 cc unit. Saab experienced reliability problems with Triumph sourced engines and decided to bring the design home.
