Alfa Romeo introduced the new 1900 series at the 1950 Paris Motor Show. The 1900 Berlina, a 4 dr. sedan, was the only model in the new series until the introduction of the 1900C coupe in 1951 and the TI sedan in 1952 and was fitted with a 1.9L engine delivering 90 hp and reaching a top speed of 171 km/h. The 1900 was the first car in Alfa's history to be built without a separate chassis.The 1900C (for corto) were mostly coupes with bodies provided by coachbuilders.
A second series with a new look and more stylish exterior design (by Touring ) came out in 1954 with a larger 1975cc Super engine with hotter cams delivering an increased output of 115 hp, a 5 speed gearbox, larger front brake drums, and twin 2 choke Solex carburetors. The Touring "Super Sprint" appellation became generic for this model and particularly so for its 1956 successor the completely restyled and more modern 3rd series variants known as Super Sprints ( commonly called the 3 window coupe). Other notable coachbuilders were Castagna, Boano and Zagato in particular whose sporty design became popular for competition work and are today the most sought after model by far. About 2000 of the C chassis cars were produced.
The TI in particular was successful in racing as well as the Zagatos and Touring Sprints. Wins in notable events such as the Targa Florio and the Mille Miglia certainly helped Alfa Romeo sell more than 20,000 units of 1900 cars until production was discontinued in 1959.
