The Syrena 105 was a Polish automobile model by the Fabryka Samochodów Osobowych (FSO) in Warsaw and from 1972 to 1983 by Fabryka Samochodów Małolitrażowych (FSM) in Bielsko-Biała.
History
The Syrena was produced in various models: 100, 101, 102, 103, 104, while the most popular model was the 105. All were 2-door sedans with two-stroke engines, initially of two cylinders. In 1965 the Syrena received a larger 3-cylinder Wartburg developed engine at roughly the same time as Wartburg launched their new 353 model based on the Polish Warszawa 210.
Syrena 105 was assembled in two factories – in FSO (1972), like the earlier models, and in FSM (1972–83). Unlike its predecessors it had regular front doors instead of "suicide" ones. The "Lux" version, produced from 1974, had the gear lever and handbrake between the front seats. The 105 served as a basis for two other models – Syrena R-20, which was a pick-up and a van. Bosto Fitted with an 842-cc front 2 stroke; 3 cylinders, vertical, in line Engine driving the front wheels from a 4 speed fully synchronized gearbox. With worm and roller steering and front and rear drum brakes.
