The Fiat 1500 was a car produced by the Fiat from 1935 to 1950. The car was introduced in Salone dell'Automobile di Milan in 1935. It was one of the first cars tested in a wind tunnel, following the Chrysler Airflow produced one year earlier. The styling was by the emerging designer, Giacosa, who achieved an aerodynamic efficiency unequalled before it in a touring car, and (contrary to the failure of the "lumpen" Airflow) disproved the thesis aerodynamic cars would not sell.

The second series 1500B, with better brakes, was introduced in 1939, and in 1940, the 1500C, with a redesigned front end.

In 1949, the 1500E appeared, having some exterior changes and the external spare wheel moved inside the car.
