After its introduction in 1966, the 275 GTB/C was raced by several independent racing teams with varying degrees of Ferrari factory support, including NART, Maranello Concessionaires, Scuderia Filipinetti, and Ecurie Francorchamps. Three 275 GTB/Cs were entered in the 1966 24 Hours of Le Mans, two of which finished. The Maranello Concessionaires-entered 275 GTB/C (chassis 09035) driven by Roy Pike and Piers Courage finished 8th overall and 1st in class, while the Ecurie Francorchamps 275 GTB/C (chassis 09027) driven by Claude Dubois and Pierre Noblet finished 10th overall and 2nd in class. Other notable victories include a 1st in class at the 1967 Targa Florio, driven by Tullio Sergio Marchesi. Marchesi went on to win the 1966 and 1967 Italian GT Championships driving 275 GTB/C chassis 09007.
