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.

Specific for Syrena Sport was the independent rear suspension, with trailing arms, torsion bars and almost horizontal hydraulic dampers.

Cezary Nawrot on purpose designed a very low and flat bonnet, to avoid a standard 2-stroke 2-cylinder S-15 engine (used in other Syrenas) to be installed in this car.

Stanisław Łukaszewicz was the chief designer of another important innovation: self-supporting chassis with strengthened floor panel - other Syrenas at that time used traditional steel ladder frame.

A frequently quoted (although not fully substantiated) story says that either the Prime Minister Józef Cyrankiewicz[3] or the First Secretary of the Communist Party Władysław Gomułka[4] personally called the factory and ordered to moth-ball the project.

Until that moment, the car had driven some 29,000 km on the factory test track and on public roads outside of the FSO, and generally proved to be adequately designed.

The surviving historical material are a few dozens black and white and hand-coloured photographs, press articles and plans drawn by Zbigniew Grochowski, which were published in "Mały Modelarz" model-makers' magazine in 1961.

[5] This modified car was in turn not mass-produced either, and until the end of production in 1983 Syrena had a non-independent rear suspension, with transverse feather-coil and rigid axle.
