[2] 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 1300/1500 were conventional cars, with longitudinally, front-mounted engines powering the rear axle via a four-speed manual transmission with a column gearchange.

Because of the shared design and components, Fiat saved a lot of money and development time.

This longer version was called the 1500 C and also received three more horsepower (for a total of 75) and various other detail differences, including power brakes and bigger taillights with built-in reverse lamps.

The Pininfarina-designed Coupé and Cabriolet models of the preceding 1200 continued with largely unchanged bodywork, although they were now equipped with the larger 1.5 litre engine.

[7] In South Africa, dealers could also supply the "1500 OTS", a conversion for more power available in two different stages.

[8] The OTS was developed by CMI (Cartoria Motor Industries) specifically to suit local production car competition regulations.

Siata, the Italian tuning accessories and special vehicles manufacturer, devised a model called TS or 1500 TS that differed from the regular Fiat saloon in styling details, including two-tone paint, but mainly in the fact that the engine was tuned to deliver as much as 94 bhp (70 kW).

[13] For South American market Fiat Concord in Buenos Aires from 1963 produced a 1500 version.

These later versions no longer required Fiat Concord to pay (steep) royalties to Vignale.
