Due to perennial strikes in Italy, Ferrari could afford to enter only two cars (Ferrari P3s) for the 1966 24 Hours of Le Mans instead of its usual entry of three prototypes. Uncertainty and confusion surrounds subsequent events and their consequences, and a number of different explanations have been offered in the decades since. The narrative explained by Ferrari at the time states that under Le Mans rules in 1966 each car was allowed only two drivers. Surtees was omitted from the driver line-up with one works Ferrari to be driven by Mike Parkes and Ludovico Scarfiotti, and the other by Jean Guichet and Lorenzo Bandini. When Surtees questioned Ferrari team manager Eugenio Dragoni as to why, as the Ferrari team leader, he would not be allowed to compete, Dragoni told Surtees that he did not feel that he was fully fit to drive in a 24-hour endurance race because of the injuries he had sustained in late 1965. However, Surtees himself described things somewhat differently. In his recollection, when the pairings were announced he was to drive alongside Scarfiotti. As the faster driver of the two, Surtees argued that he should take the first stint and "try to break" the Ford opposition by driving "flat out from the start". Dragoni denied Surtees's request and insisted that Scarfiotti take the start, supposedly to please Fiat chairman Gianni Agnelli, Scarfiotti's uncle, who was in attendance as a spectator. Either way, the decision and subsequent lack of support from Enzo Ferrari himself were deeply upsetting to Surtees and he immediately quit the team. This decision likely cost both Ferrari and Surtees the Formula 1 Championship in 1966. Ferrari finished second to Brabham-Repco in the Constructors' Championship and Surtees finished second to Jack Brabham in the Drivers' Championship. Surtees finished the season driving for the Cooper-Maserati team, winning the last race of the season.
