The Giulietta Sprint, whose body was designed by Bertone, was introduced as a prototype at the Salone dell’automobile in Turin in 1954. This was unusual because it was introduced before the sedan version. The engine had a twin camshaft, as per Alfa Romeo tradition, and it went on sale for 1.9 million Italian liras. Even though this was not very cheap, it was far less than the 3.21 million lira of the 1900 Super Sprint coupé Touring. Its racing debut was the Giro di Sicilia in 1955, but at the MM it was very unlucky. It performed well but was beaten by the more sporting Porsche 1300. Porsche once again demonstrated its supremacy at the end of the season in Monza for the Coppa Intereuropa, and the new Siata 1250, derived from the Fiat 1100/103, in early spring of 1956 looked to offer a real challenge.

Just in time for the MM of 1956, the Sprint was backed up by the Veloce, a model distinguished for its increased power and its lightened weight the windows of the car opened length-wise, becoming a distinctive external element of the car. Starting in 1956, the Alfa Romeo Giulietta Sprint Veloce had a continuous racing season as the result of some significant technical improvements compared to the normal Sprint model; the small four cylinders, 1290 ccs engine was increased in power from 80 to 90 bhp thanks also to the use of two twin barrel horizontal carburettors. With a top speed of 180 kph, the Sprint Veloce became the dream of many sports gentleman-drivers. In a Sprint Veloce, Sgorbati took an exceptional eleventh place in overall ranking in 1956 Mille Miglia. In 1957, 700 units were built.

Chassis AR1493E*04349 took part in the last Mille Miglia with Rinaldo Parmigiani, who gained 40th place in the overall classification after 13hr, 06' 47” of racing.
