Alfa Romeo Giulietta 750 Series: Restoration and Bodywork

The Giulietta 750 Series was introduced in 1954 at the Turin Motor Show. The first Giulietta 750 series model was the Sprint, an elegant, compact coupe designed by Franco Scaglione at Bertone. This model was followed by a saloon, or berlina, in 1955 and a 2 seater spider was introduced in mid 1955. The spider featured pretty bodywork designed by Pininfarina.

In 1957 the berlina became available in a Ti (Turismo Internazionale) version. All the Giulietta cars used the classic four cylinder, twin cam engine in 1300cc form which was available in normale or veloce versions.

The 750 and 101 Series cars were also manufactured as SZ and Sprint Speciale coupes, designed by Zagato and Bertone respectively, and these cars were originally developed primarily for competition. 

  

The Sprint Zagato (SZ) was a race version Giulietta that was specially prepared by Zagato in direct agreement with Alfa Romeo. It was based on the shorter chassis of the Giulietta Spider combined with the mechanicals of the racier Sprint Veloce. Franco Scaglione designed the body in Bertone's studio, while the aluminum panels were beat out by hand at Zagato's workshop. Because of its small size, and aluminum bodywork, the SZ was much faster than its steel-bodied production counterparts. Furthermore, the car used a space frame chassis, which was totally unlike the production Giulietta. Zagato also used perspex side windows and a relatively sparse interior to help reduce weight. The SZ was first shown at the Geneva Motorshow in March 1960. The overall shape of the car reflected the unofficial Sprint Veloce (SVZ) cars which were rebodied by Zagato as early as 1956. The last 30 of the 200 car production run featured a long tail called the 'Coda tronca'. The entire body was much longer, and was designed to penetrate the air better. Detail changes included a cut-off Kamm tail, narrower front air intake, a lower roof and the use of disc brakes up front. By 1959 the SZ's replacement the Tubulore Zagato (TZ) was well underway. After extensive development the car was finally launched in 1963.

The Sprint Speciale version was a aerodynamic sports coupe manufactured from 1959 to 1966, The first prototype of the Giulietta Sprint Speciale was presented in 1957 at the Turin Motor Show. After two more prototypes were presented at car shows, the official launch of the production version was in 1959 on the Monza race track. The first 101 cars produced had the "low nose" and 750SS designation. 100 cars minimum were needed to homologate a car in FIA regulations and all these cars had steel bodies with an aluminium bonnet, boot lid and doors. Also, the first cars were equipped with Weber 40 DCO3 carburetors, later changed to 40 DCOE2. There were some all-aluminium cars produced. The drag coefficient of the Sprint Speciale is 0.28 and was not improved on by other manufacturers for more than 20 years. The Giulietta cars used the 1,290cc twincam engine. The Sprint Speciale was originally designed as a real race car for competition and there were small changes for the production version including; steel doors, Weber 40 DCOE2 carburetors, higher front nose and removal of the plexiglas windows. In addition, bumpers were fitted front and rear. With the 1,290cc engine and 100 hp the maximum speed was around 120 mph. All Giulietta Sprint Speciales had 3-shoe front drum brakes and drum brakes at the rear. The bigger engine 1600cc Giulia series replaced the Giulietta and was introduced in March 1963. The 1,570cc engine with Weber 40 DCOE2 carburetors was taken from Giulia Sprint Veloce and delivered 112 hp of power. Most Giulias SS had disc brakes fitted at the front. An easy way to distinguish the Giulia SS from the Giulietta SS is by the different dashboard design. 1,366 Giulietta Sprint Speciales and 1,400 Giulia Sprint Speciales were produced and production ended in 1966.

 

The Giulia 101 Series replaced the 750 Series when the 1600cc engine was introduced. The new Giulia cars had a longer wheelbase for more passenger room. The Spider, Sprint and Sprint Speciale 101 Series Giulias were introduced together with the Giulia berlina. The easiest to distinguish from a Giulietta is the Spider, which featured a bonnet bulge to clear the slightly taller engine.

The Giulietta 750 Series was produced until about 1960 when the Giulia 101 Series cars were phased in.
