The 1982 San Marino Grand Prix was already an unusual race before a wheel had turned in anger. A dispute between the sport's governing body and the British-based FOCA constructors had led to a boycott by most of the competitive field — Brabham, Williams, McLaren, Lotus and others stayed away. What remained was a reduced entry dominated by the turbocharged Ferraris of Gilles Villeneuve and Didier Pironi, the Renaults and Alfa Romeos. It was not a representative Formula 1 field, but it was the field that raced at Imola that April afternoon.
Ferrari, with a commanding advantage over the remaining opposition, issued team orders: the two cars were to circulate in the positions they held after the pit stops and bring the result home. Villeneuve had led the race; Pironi was behind him. The instruction was to hold station. Villeneuve, understanding the arrangement, began managing his pace in the closing laps. He eased off, confident of the win.
Pironi drove past him. Villeneuve assumed it was a performance demonstration for the crowd, that Pironi would fall back into position as Ferrari had instructed. Instead, the Frenchman kept going — past Villeneuve, away from Villeneuve, and across the finish line first. Villeneuve crossed the line seconds later, furious. The post-race images show him gesturing from the cockpit, his face — what was visible of it — taut with the anger of a man who had been deceived by his teammate.
Villeneuve refused to speak to Pironi at the podium or anywhere afterwards. He told the press he would never trust his teammate again. He left Imola with the explicit intention of putting the fastest possible lap in qualifying at the next race — the Belgian Grand Prix at Zolder — to demonstrate that he, not Pironi, was the faster driver. In qualifying on May 8, 1982, two weeks after Imola, Villeneuve's Ferrari ran into the back of Jochen Mass's March at high speed. The car was launched into the air. Villeneuve died of his injuries that evening.
