Syrena Sport was 2-door coupe with a fibreglass body on a steel chassis with strengthened floor panel. The engine was a new design 4-stroke 2-cylinder air-cooled boxer engine with aluminium block. The cast-iron cylinders, cylinder heads and pistons were from the S-03 engine of the Polish motorcycleJunak. The prototype engine was fitted with accessories (carburettor, ignition, etc) from a French car Panhard Dyna Z. It had a displacement of 700 cc and developed around 35 bhp (26 kW) at 6000 rpm, which provided adequate performance for this light car (710 kg). The engine was placed in front of the front axle and powered front wheels through a 4-gear manual gearbox, identical with that of Syrena 100. The front suspension was not identical with that from the classic Syrena, but based on the same concept: independent with single transverse feathercoil, lower A-wishbones and hydraulic dampers. Single-circuit drum brakes were installed on all wheels. Specific for Syrena Sport was the independent rear suspension, with trailing arms, torsion bars and almost horizontal hydraulic dampers. Another difference was a floor gear-shift mechanism and hydraulic-operated clutch. Wikipedia, the free encyclopedia.
