ALFA ROMEO

Giulietta Sprint Speciale

The first prototype of the Giulietta SS was presented in 1957 at the Turin Motor Show. After two more prototypes were presented in car shows, the official presentation of the production version for the press was on 24 June 1959 on the Monza race track. The first 101 cars produced had "low nose" and 750 SS designation. 100 cars minimum were needed to homologate a car in FIA regulations. While there were some all-aluminium cars produced, the majority of these cars had steel bodies with aluminium doors, engine bonnet and boot lid. Also first cars were equipped with Weber 40 DCO3 carburettors, later changed to 40 DCOE2. The drag coefficient of the Sprint Speciale is 0.28, the same as a Chevrolet Corvette (C6), and was not surpassed for more than twenty years. Cars used the 1,290 cc Alfa Romeo Twin Cam engine, a design with hemispheric combustion chambers and valves controlled directly by twin overhead camshafts.
