The Fiat 1400 was introduced at the
1950 Geneva Motor Show. It was the first
unibody Fiat automobile. In 1953, the introduction of a diesel version with a 1900 cc engine marked another Fiat first, although the diesel version was known as the 1400 Diesel. Also in 1953, the 1400 entered production in Spain as the
SEAT 1400, the first model produced by
SEAT. The following year it also became the first passenger car produced by
Crvena Zastava in
FNRY, the
Zastava 1400 BJ. Equipped with a 2.0 litre
Steyr engine, it was produced as "Steyr 2000" by
Steyr-Daimler-Puch AG in
Austria from 1953. The Fiat 1900, introduced in 1952, was an upmarket model that used the same body as the 1400, but came with a 1.9 litre engine and more standard features. The petrol-engined Fiat 1900 A, introduced in 1954, now offered a claimed 70 bhp. Unusually for that time, it featured a 5-speed column shifted manual transmission. The engine and transmission of the Fiat 1400/1900 were used in the
Fiat 615 truck and
Fiat Campagnola SUV. ==Features==
