The Alfa Romeo 33/3 made its debut in 1969 at the 12 Hours of Sebring. The engine was enlarged to 2998 cc (183ci) with 400 hp (298 kW), which put the 33/3 in the same class as the Porsche 908 and the Ferrari 312P. The new car did poorly at Sebring and Alfa did not take part in Le Mans after Lucien Bianchi’s death in a practice session. The car took a couple of wins in smaller competitions but overall the 1969 season was not a successful one, and Alfa Romeo was placed seventh in the 1969 International Championship for Makes.
In 1970 the bigger 5.0L Porsche 917 and Ferrari 512 dominated, yet Toine Hezemans and Masten Gregory took third overall at Sebring, and Andrea De Adamich and Henri Pescarolo won their class in the 1000km Zeltweg, finishing second overall. Also in 1970, an Alfa T 33/3 was one of the “actors” of Steve McQueen’s movie Le Mans, released in 1971.
