The Alfa Romeo Giulietta (series 750 and 101) was a subcompact automobile manufactured by the Italian car maker Alfa Romeo from 1954 to 1965. The first Giulietta model was a coupé, the Alfa Romeo Giulietta Sprint, introduced in late 1954. This was followed by a sedan in spring 1955 and in mid 1955, the open two-seat Alfa Romeo Giulietta Spider, featuring convertible bodywork by Pininfarina. The Alfa Romeo Giulietta used an Alfa Romeo Twin Cam engine of 1290 cc straight-4, with light alloy cylinder block and alloy cylinder head with twin overhead camshafts. The original Alfa Romeo Giulietta engine produced a power output of 53 bhp in the sedan and 80 bhp in the Alfa Romeo Giulietta Sprint. This was to be increased to 100 bhp in later sporting models such as the Alfa Romeo Giulietta Sprint Speciale and the Alfa Romeo Giulietta SZ (Sprint Zagato).
