The Fiat 1100/103 was introduced in 1953; compared to the 1100 E it had modern 4-door saloon body sporting integrated fenders and front lights. The new model was called the 1100/103 after its project number. In October 1953, the car became available in a sporty version, the 1100 TV (Turismo Veloce) with a third light in the middle of the grille and 51 PS (38 kW) rather than the 36 PS (26 kW) of the regular versions.

The Fiat 1100 TV coupe was displayed as a prototype at the Paris Motor Show in 1953. It was designed under the guidance of Fiat's head designer, Giovanni Zoboli by Esparsa Comprenelli. The Italian coachbuilder Pinin Farina handed the construction from 1954 to 1957 of the Turismo Veloce coupe body that sat on the standard 1100 sedan frame. It incorporated advanced technical solutions developed by Sergio Farina’s brother-in-law Renzo Carli. The car was marketed by a network of Fiat-approved independent dealers. The Coupe also utilized the sedan’s transmission and 1089cc powerplant, albeit with increased performance for a top speed of over 80mph. Acceleration was steady with a 0-60 mph time under 26 seconds.

The Fiat 1100 TV were made in two series: the first (1954-1955) has a little rear window. The second (1955-1957) is especially recognizable for a typical Pinin Farina panoramic rear window wide. The production of the GT Coupe version of the 1100TV was far lower than the more familiar convertible. Luciano Ciolfi won the Italian Touring Car Championship in an 1100 TV and Umberto Agnelli also raced a Turismo Veloce several times.
