Sanesi's main role at Alfa Romeo was as a test driver, but he was also given numerous opportunities to drive the superb Tipo 158/159 series cars in races. In 1946, he won his heat and finished third in the Milan GP, while in 1947 he was second to Varzi at Bari and third in the Italian GP held at Sempione Park after claiming pole position. The following year saw Consalvo take second place in the French GP and third with fastest lap at the Monza Autodrome GP. In 1949 Alfa Corse did not compete in Formula 1, though Sanesi finished second in the touring car class in the Mille Miglia with an Alfa, and when the team returned in 1950 he drove in only one Grand Prix but won the Coppa Inter Europa sports car race at Monza. Consalvo had his most active Grand Prix season in 1951, scoring points in two of his four starts, but after Alfa's withdrawal from Grand Prix racing at the end of the year, he concentrated fully on sports cars, winning his class in the 1954 Carrera Panamericana. A testing accident later that year with the Disco Volante left him with serious injuries, but he returned to competition in 1955, taking second place in the Verminico hill-climb with a 1.9 Alfa. He raced on in sports cars to the mid-1960s.
