The first Giulietta model was a coupé, the Giulietta Sprint, introduced in late 1954. This was followed by a sedan in spring 1955 and in mid 1955, the open two-seat Giulietta Spider, featuring convertible bodywork. In 1957, the most powerful version, called Giulietta TI (Turismo Internazionale) was presented with minor cosmetic changes. A new version of the Giulietta debuted at the Frankfurt Motor Show in 1959 with a new series number and various optical changes. The Alfa Romeo Giulietta has been awarded a prestigious five-star Euro NCAP rating, setting it at the top of its segment in the field of safety.
