Didier Joseph Louis Pironi (26 March 1952 – 23 August 1987) was a French racing driver and offshore powerboat racer, who competed in Formula One from 1978 to 1982. Pironi was runner-up in the Formula One World Drivers' Championship in 1982 with Ferrari, and won three Grands Prix across five seasons. In endurance racing, Pironi won the 24 Hours of Le Mans in 1978 with Renault.
Born and raised in Val-de-Marne, Pironi was the half-brother of racing driver José Dolhem. After initially studying engineering, he enrolled at the Winfield Racing School at Paul Ricard, earning a scholarship to compete in Formula Renault, where he won the Eurocup in 1974 and 1976. After finishing third in the 1977 European Formula Two Championship, Pironi progressed to Formula One in 1978 with Tyrrell, making his debut at the Argentine Grand Prix. Pironi retained his seat at Tyrrell the following season, achieving his maiden podium at the Belgian Grand Prix. He moved to Ligier in 1980 to partner Jacques Laffite, taking his maiden win in Belgium—amongst several podiums—as he finished fifth in the standings.
Pironi's performances at Ligier attracted the attention of Enzo Ferrari, who signed him to Ferrari in 1981 as the teammate of Gilles Villeneuve. Whilst leading the 1982 World Drivers' Championship, having controversially won the San Marino Grand Prix amid the FISA–FOCA war, Pironi was seriously injured during qualifying for the German Grand Prix; he crashed his Ferrari 126C2 in very wet conditions, severely injuring his legs. The accident came three months after the death of Villeneuve, whose fatal crash was attributed to his rivalry with Pironi. He ultimately lost the title by five points to Keke Rosberg. He retired from racing with three wins, four pole positions, five fastest laps and 13 podiums in Formula One.
Outside of Formula One, Pironi entered four editions of the 24 Hours of Le Mans from 1976 to 1980, winning in 1978 alongside Jean-Pierre Jaussaud, driving the Renault Alpine A442B. He was also a race-winner in the BMW M1 Procar Championship. In August 1987, Pironi died in an offshore powerboat racing accident near the Isle of Wight.
Pironi was born in Villecresnes, Val-de-Marne. He is the half-brother and first cousin of José Dolhem (they had the same father and their mothers were sisters). He began studying as an engineer and earned a degree in science, but entering the family construction business fell by the wayside following his enrollment at the Winfield Racing School at Paul Ricard, graduating with a prestigious Volant Shell Competition Scholarship (free one Formula France season entry) as the best student of 1972.
Professional driving career (1972–1982)
The program was designed to promote young motorsport talents, that also led Alain Prost, René Arnoux and Patrick Tambay into Formula One. He became Formula France champion in 1974, taking the Super Renault championship title in 1976 and winning the prestigious Monaco Grand Prix Formula Three support race in 1977.
Pironi signed with Tyrrell and made his F1 debut at the Argentine GP on 15 January 1978. Ken Tyrrell's team which, despite being British, had a strong working relationship with Elf, dating back to the late 1960s.
In the same year, Pironi was part of the massive Renault squad tasked with winning the 24 Hours of Le Mans. Partnering Jean-Pierre Jaussaud in the team's second car, the unusual "bubble roof" A442B, he won the race by four laps from the rival Porsche 936s.
Two seasons with the underfinanced Tyrrell team demonstrated enough promise for Guy Ligier to sign Pironi to his eponymous French team in 1980, a season in which Pironi recorded his first victory, in the Belgian Grand Prix at Zolder, as well as several podium finishes. The Ligier JS11/15 was an excellent car but was unable to reach its maximum potential. A combination of the team's incompetence and Jacques Laffite being in firm political control meant that Pironi was not going to win the championship with Ligier.
Pironi's performance piqued Enzo Ferrari's interest in the Frenchman's services, which he secured for 1981. Ferrari later recalled, "As soon as Pironi arrived at Maranello, he won everyone's admiration and affection, not only for his gifts as an athlete, but also for his way of doing things - he was reserved while at the same time outgoing."
Teamed and compared with Ferrari's lead driver Gilles Villeneuve, who welcomed the Frenchman and treated him as an equal, Pironi was slower in qualifying but steadier in races during his first season with Ferrari.
Establishing a fine rapport with the senior members of the team, Pironi arguably exploited this good relationship in the aftermath of the controversial 1982 San Marino Grand Prix, where Pironi is widely thought to have duped Villeneuve into conceding victory by giving the impression that he would finish behind his teammate, only to unexpectedly power past him into the Tosa hairpin, despite the team having signaled both drivers to slow down. Villeneuve was furious with Pironi and vowed never to say another word to him. The Canadian was killed in qualifying two weeks later at the following Belgian Grand Prix at Zolder trying to beat Pironi's lap time. Many believe that this was foremost on Villeneuve's mind at the time of his fatal accident.
Harvey Postlethwaite (the co-designer of the 126C2) believed that the "drama" following San Marino was blown out of proportion by the press, "Villeneuve was really upset because he felt he should have been handed the race on a plate... They were competitive and either of them could win."
Pironi also mentioned a technical reason as to why the two Ferraris were swapping places so often during the San Marino race. "The (Ferrari 126C) turbo pressure was very, very difficult to control. Most of the reason that they were able to pass one another so evenly was that one would go through a sticky patch and sort of only be giving 4-bar of boost or 4.2, and the other would be getting a burst of 4.5, so it would have the legs of the other guy. It wasn't quite as spectacular as it appeared at the time."
According to Ferrari's chief mechanic Paolo Scaramelli, the team had agreed before the race that if the two Renaults were out, the drivers should have maintained position. Pironi did say a deal took place but the terms were more complex, "We had a meeting before the race; Arnoux, Prost, Gilles and me, in my motorhome. We agreed to make a spectacle for the first half of the race so long as our positions on the lap after half-distance were the same as on the grid. We started the real race at half-distance and so had plenty of fuel. The team (Ferrari) didn't know that, Marco Piccinini and Gérard Larrousse (Renault F1's team manager) didn't know, only the mechanics knew, but Prost and Arnoux - they will tell you the same." Pironi went on to add, "When I passed Villeneuve the first time, this was because he had made a mistake and had gone off the circuit. The first slow sign we got was a few laps after that, and by then we knew we had a lot of fuel left because of the way we drove the first half of the race."
In a 2002 interview with Motor Sport, Marco Piccinini supported Pironi's view, "It was a genuine misunderstanding triggered by Gilles making a mistake. He went off the circuit slightly and Didier passed. The sign was hung out because we were 1-2, not because we favored one driver over the other. We didn't favor either because it was at an early stage of the championship. We just wanted to maintain 1-2."
In 2007, former Marlboro marketing executive John Hogan (whose company sponsored Pironi in his time as a Ferrari driver) disputed the claim that Pironi had gone back on a prior arrangement with Villeneuve. He said: "I think Gilles was stunned somebody had out-driven him and that it just caught him so much by surprise."
