Alfa Romeo · 1966–1967

Alfa Romeo Tipo 33

The Alfa Romeo Tipo 33 was range of sports racing prototypes raced by the Alfa Romeo factory-backed team between 1967 and 1977. Initially it was powered by a 2 liter V8. Originally intended as 50 cars for Group 4 homologation, less than two dozen road going cars were derived from it in 1967, called Alfa Romeo 33 Stradale. Later versions had the V8 increased to the 3 liter size allowed since 1968 for Group 6 prototypes in the World Sportscar Championship, but there it had to face also 5 liter engines in Group 4 sportscars that had been built in series of 25 or more. Anyway, the T33/3 won three races of the 1971 World Sportscar Championship otherwise dominated by Porsche 917. The T33 cars took part for Sport Cars World Championship, Nordic Challenge Cup, Interserie and CanAm series. Alfa then moved on to a 3 liter flat-12 engine later also used in Brabham F1 cars, and in Alfas own F1 car. The 33TT12 Alfa Romeo won the 1975 World Championship for Makes, and the 33SC12 the 1977 World Championship for Sports Cars, taking the first place in all eight of the championship races.
