The Fiat 1400 and Fiat 1900 are passenger cars produced by Italian automotive manufacturer Fiat from 1950 to 1958 and from 1952 to 1959 respectively. The two models shared body and platform, but while the 1.4-litre 1400 was Fiat's intermediate offering, the upmarket 1900 had an enlarged 1.9-litre engine and more luxurious trim and equipment, to serve as flagship in the manufacturer's range.

Dante Giacosa was an Italian automobile designer and engineer responsible for a range of Italian automobile designs — and for refining the front-wheel drive layout to an industry-standard configuration.
