The Syrena 110 was a Polish automobile prototype from the mid-1960s, manufactured by the Fabryka Samochodów Osobowych (FSO) in Warsaw.

In 1961 there started works in the Automotive Industry Construction Bureau (Biuro Konstrukcyjne Przemysłu Motoryzacyjnego, BKPMot) upon a new small family car to replace the FSO Syrena, which was quite new at that time, but was not a modern design.

[1] The Syrena 110, that could become a modern and practical popular car, fell victim to a communist planned economy.

In view of limited resources of the FSO factory, and neglecting needs for a popular mass-produced car, the Polish authorities decided to cease further works upon the Syrena 110, because of a license agreement to manufacture a mid-class Polski Fiat 125p.

[1] Only in the 1970s, after a political change, there appeared a much smaller popular car Polski Fiat 126p.
