The Alfa Romeo Tipo 33 is a series of racing cars built and developed by Alfa Romeo in the 1960s and 1970s. The Tipo 33 was designed for endurance racing and made its debut in 1967.
The first model, the Tipo 33 Stradale, was a road-going version of the race car. It was powered by a 2.0-liter V8 engine, which produced 230 horsepower. Only 18 examples were built, making it one of the rarest and most desirable Alfa Romeos ever made.
The Tipo 33 made its racing debut in the 1967 Targa Florio, where it finished third overall. The car went on to win the 1000 km Nürburgring race in the same year. The Tipo 33 would go on to win many more races over the years, including the 24 Hours of Daytona and the 12 Hours of Sebring.
In 1968, Alfa Romeo introduced the Tipo 33/2, which featured a new 2.0-liter V8 engine that produced 270 horsepower. The car was extremely successful in endurance racing, winning the 1000 km Monza race in its first year.
In 1969, Alfa Romeo introduced the Tipo 33/3, which featured a larger 3.0-liter V8 engine that produced 400 horsepower. The car won the 1000 km Nürburgring race in 1970 and the 12 Hours of Sebring in 1971.
In 1972, Alfa Romeo introduced the Tipo 33 TT 3, which featured a new aerodynamic body and a 3.0-liter V8 engine that produced 460 horsepower. The car won the 1000 km Monza race in 1972 and the 6 Hours of Watkins Glen in 1975.
The Tipo 33 continued to be successful in racing throughout the 1970s, but Alfa Romeo decided to retire from endurance racing at the end of the decade.
The Tipo 33 is widely regarded as one of the most successful and iconic racing cars ever produced by Alfa Romeo. Its racing success helped establish the brand as a serious competitor in the world of motorsport.
