The Fiat 1300 and Fiat 1500 were manufactured from 1961 to 1967. They were essentially identical except for their engine displacement, as indicated by their model names. They were available as a saloon and station wagon, and as convertible and coupé models which shared little mechanically with the other body styles except the engine. The car’s 75 hp engine combined with its lightweight construction was unusual for the time, especially when considering the price.

The 1300/1500 and their derivatives were also assembled by Yugoslavia’s Zastava and Fiat’s German subsidiary, Neckar Automobil AG, as well as in South Africa. The floorpan of the 1500 C was used as a basis for the 1500s replacement, the Fiat 125, while another model, the Polski Fiat 125p, made by the Polish FSO, was created by mating the body of 125 and mechanicals (engines, gearbox, transmission, suspension) of 1300/1500. In the Italian range, the 1300 was replaced by the Fiat 124 in 1966, and the 1500 by the Fiat 125 a year later.

In total, 1,900,000 units were produced worldwide.
