In May 1962, Alfa Romeo presented the street version of the Giulia to the trade press in Monza Park. The vehicle with a rear comb was built under the guidance of Orazio Satta in a wind tunnel. With the help of wool threads and soot spray, the engineers developed a completely new, more streamlined design. This resulted in a sensational cw value of 0.34 in the 1960s, and one year later the racing history of the Giulia TI Super began. For the racing version, Alfa Romeo lightened up the interior and replaced the drum brakes at the front with disc brakes. The continuous bench of the street-limousine had to make way for two separate bucket seats. Both the engine block and the cylinder head were made of cast aluminium. A double chain took over the valve control, a double carburettor supported the engine and gave the car its unmistakable sound. To improve road holding, Alfa Romeo also used upper wishbones on the front axle. Extra-light magnesium aluminium alloys from aircraft construction were used for the rims. The Giulia TI Super weighed 90 kilograms less than the comfortable saloon. Engineers elicited 112 hp from the 1.6-litre engine. The Italian athletic rider thus reached a top speed of 190 km/h. Alfa Romeo built 501 vehicles from the homologation models for motorsport. The race cars could only be purchased by private racers.
