Fiat introduced its 1100-103 (103 was the project number) two-seat cabriolet in the mid-1950s at the Geneva Motor Show. It was called the 'Trasformabile,' Italian for convertible, and is generally considered the creation of design director Fabio Luigi Rapi the department head of Fiat's in house special bodies division known as Dipartimento Carrozzerie Derivate e Speciali. It had a wrap-around windshield, divided mesh grilles, and a forward-leaning stance. Amenities included an adjustable steering wheel and roll-up windows.
Trasformabiles received the Turismo Veloce (fast touring) engine which added 12 additional horsepower over than standard model thanks to higher compression and twin-choke Weber carburetors. Approximately one thousand examples were built before the 1100cc Trasformabile roadster's were replaced by the updated 1200 model.
Fiat introduced the 1200 TV Trasformabile two-seater roadster at the 1957 Turin Motor Show. It was an updated version of the Fiat 1100 TV Trasformabile with the 1,221cc engine developing 55 horsepower in standard form. The car's seat now swiveled for easier egress and entry and the headlight size increased. They had new bumpers with taller over-riders moved further inboards, and there was a strip speedometer. In export markets, it was called the 1200 Spider.
