Designed by Carlo Chiti, a famous Italian engineer, the several variants of the car were raced by the Alfa factory and by many privateers as well.
After the initial victories in the 2-litres Prototype category, the ‘T33/3’ version made its debut in 1969 and gained its best results in the 1971 World Championship: the Autodelta ‘open’ Prototypes won the overall ranking at Brands Hatch, Watkins Glen and the Targa Florio, being even faster than the 5-litres ‘Sport’ cars. The ‘T33/3’ cars featured a monocoque chassis, paneled in aluminum and magnesium, a V8 2998 cc engine, and a 6 or 5 speed gearbox. Top speed reached 330 km/h, at Le Mans with long tail. This specific model of the Alfa 33/3 reproduces the car owned by Alfa Romeo collector Joe Nastasi, as it was tested on the Pocono circuit. The same car is often seen at various historic car shows and races, such as the Targa Florio of 2014.
