Syrena Bosto

The Syrena Bosto was a model of Polish automobile.

The Syrena Bosto and its sister, the R-20, were first introduced to the 104 models of Syrena. The name is an acronym of Bielski Osobowo-Towarowy, or Passenger-Cargo [car] of Bielsko. The first model of the Bosto was revealed in December 1971, at the newly constructed FSM factory in Bielsko-Biala in southern Poland. The final model finished production 30 April 1983. Overall, approximately 135,000 were built.


The Bosto 104B started official production in 1972, and was available as a 4-person van, capable of carrying 200 kg of freight, or as a two-seater cab with a 350 kg load rating. The second edition, Syrena Bosto 105B, replaced the 104 in 1976. Essentially the same vehicle stylistically, the differences were in construction. Uprated semi-elliptical springs from the FSO Warszawa, an increased fuel tank from the FSO 125p, and the handbrake moved to the "standard" position between the front seats were the main modifications. It was NOT a rear wheel drive vehicle, and it was put to this category by mistake. The 3-cylinder, 2-stroke engine was mounted longitudinally in front of the front axle and powered front wheels through a gearbox with driveshafts coming sideways out of it.



Weight: 950 kg Wheelbase: 2300mm Length: 39650mm Rear Compartment: H-1600 mm x W-1470 mm


Because the Bosto was designed for heavy loads, as opposed to the sedan version of the Syrena, the suspension underneath was modified. An extended chassis held a rear trailing axle on leaf suspension, each with a hydraulic suspension damper. This allowed a lower floor level, and in turn allowed FSM to borrow directly parts from the Zuk A05/A06.


The driver's compartment was separated from the rear load space by a single sheet bulkhead, and additional roof-fixed netting.
