To distinguish between the models, Fiat and FSO revived the marque Polski Fiat. After the termination of the license agreement, the car was also branded as the FSO 1300, FSO 1500 or FSO 125p.
In the 1960s, the only passenger car manufacturer in socialist Poland was the FSO in Warsaw, which manufactured the dated Syrena small car and the Warszawa, a larger model whose roots could be traced back to 1940s. Even within the realities of a centrally planned, socialist economy, the need for a replacement was felt. Although Warszawa-based replacements had been under development within the FSO, the authorities decided to pursue talks with the Italian Fiat, which was seeking to expand its international presence by establishing production in the countries of the Eastern Bloc.
