Helmut Marko
Although everyone had been outclassed by the Porsche 917s in 1971, Alfa Romeo had proven the most competitive, even getting three wins that season. For 1972 they had developed the latest iteration of the Tipo 33, the open-top T33/3. Designer Carlo Chiti used a tubular chassis rather than a full monocoque making them narrower and 50 kg lighter. The 3-litre V8 developed 445 bhp. The team picked up a number of ex-Porsche drivers for the three cars entered: Vic Elford/Helmut Marko, Rolf Stommelen/”Nanni” Galli and Nino Vaccarella/Andrea de Adamich.
