Bengt Ronnie Peterson (Swedish: [ˈrɔ̌nːɪ ˈpêtːɛˌʂɔn]; 14 February 1944 – 11 September 1978) was a Swedish racing driver who competed in Formula One from 1970 to 1978. Nicknamed "Superswede", Peterson twice finished runner-up in the Formula One World Drivers' Championship in 1971 and 1978, and won 10 Grands Prix across nine seasons.
Peterson began his motor racing career in kart racing, traditionally the discipline where the majority of race drivers begin their careers in open-wheel racing. After winning a number of karting titles, including two Swedish titles in 1963 and 1964, he moved on to Formula Three, where he won the Monaco Grand Prix Formula Three support race for the 1969 Grand Prix. Later that year he won the FIA European Formula 3 Championship and moved up into Formula One, racing for the March factory team. In his three-year spell with the team, he took six podiums, most of which were scored during the 1971 Formula One season in which he also finished as runner-up in the Drivers' Championship.
After seeing out his three-year contract at March, Peterson joined Colin Chapman's Team Lotus in the 1973 season, partnering defending champion Emerson Fittipaldi. During his first two seasons with Lotus, Peterson took seven victories, scoring a career-best 52 points in 1973. After a poor 1975 season, Peterson moved back to March and scored his final victory for the team at the 1976 Italian Grand Prix. After spending the 1977 season with Tyrrell, he moved back to Lotus for the 1978 season as number two driver to Mario Andretti. Peterson scored two wins, at the South African and Austrian Grand Prix races, and finished second in the Drivers' Championship standings despite his fatal first-lap accident at Monza during the Italian Grand Prix.
Peterson was born in the borough of Almby in Örebro, Sweden. He developed his driving style at a young age while competing in karting, and rapidly worked his way up to the pinnacle of European karting before switching to cars.
After his karting years, Peterson entered Formula Three racing in the Svebe, a 1-litre, Brabham-derived Formula car he co-designed with his father Bengt (who was a baker) and Sven Andersson.
Superb results from the outset quickly attracted the attention of the ambitious Tecno company from Italy, who signed Peterson in 1968. With them, he won the 1969 Formula Three Championship and the 1969 Monaco Formula Three race.
Even after his elevation to F1 status, Peterson still drove in lower echelon racing series (which was common at the time), winning the 1971 European Formula Two Championship driving for March.
Peterson made his Grand Prix debut in a March 701 for Colin Crabbe's works-supported Antique Automobiles Racing Team at the 1970 Monaco Grand Prix. The limited budget of Crabbe's privateer team allowed only minimal testing, and Peterson qualified 12th out of 16 cars in the race. He was ten places behind Jackie Stewart and Chris Amon, both on the front row of the grid in their newer specification 701s, but only just behind the more experienced Jo Siffert in the second works March. Peterson was the only March driver to finish the race, in seventh place. In 1971, Peterson moved up to the full March works team, and made an instant impression. Five Formula One Grand Prix second places earned him the position of runner-up to Jackie Stewart in that year's World Championship. Within that year, Peterson drove in the World Sports Car Championship driving an Autodelta Alfa Romeo to win the Watkins Glen 6 hours. Peterson stayed at March until 1973, when he signed for John Player Team Lotus to partner Emerson Fittipaldi.
Peterson's first Grand Prix win was at the 1973 French Grand Prix, held at Paul Ricard, in a Lotus 72. He took three more wins that year, in Austria, Italy and the United States, but poor reliability restricted him to only third place in the World Championship at season's end.
For 1974, the Lotus 76 was brought forth. The car, however, proved to be a failure, disliked by both Peterson and his teammate Jacky Ickx. The team therefore opted to let them drive the much older Lotus 72s. Peterson did well in the old car and claimed three more victories: the French and Italian Grands Prix, as well as the Monaco Grand Prix.
1975 was a bad year for Lotus. Peterson and Ickx were forced to drive with the now archaic 72 model, whose age was now really beginning to show.
Peterson had signed for Shadow but Lotus owner Colin Chapman convinced him to stay with Lotus due to a promise Chapman made to accelerate the rate of development on the Lotus 77. He drove the first race of 1976 in the Lotus 77 before rejoining March Engineering. Driving the March 761, he won the Italian Grand Prix.
Peterson also continued to drive sports cars, particularly for BMW in 1974 and 1975. For instance, he was paired with Hans-Joachim Stuck in a BMW 3.0 CSL for the South African "Wynn's 1000" in November 1975, where they started on pole but finished in second after a number of stops with engine vibrations, spark plug, and similar problems. Stuck and Peterson raced together for BMW in Europe, Africa, and also in North America.
In 1977, he raced for Tyrrell, driving the six-wheel Tyrrell P34B. Peterson retired from the opening four races of 1977, he spun off in Argentina, was involved in a crash with Jochen Mass's McLaren and Clay Regazzoni's Ensign in Brazil, and suffered fuel systems problems in South Africa and United States West. He finished eighth in Spain but retired at Monaco with brake failure. Peterson's only podium finish was a third place at a rain-affected race in Belgium. Hopes were high at home in Sweden but Peterson retired with ignition problems and then finished 12th at France. He had an engine failure in Britain, finished ninth at Germany and got fifth in Austria. Peterson retired with ignition problems at Holland, sixth in Italy and 16th in the United States. Peterson retired from the last two races of 1977, a fuel leak in Canada and in Japan, he collided with Gilles Villeneuve's Ferrari but the crash killed a marshal and photographer as they were standing in a prohibited area of the track when the accident occurred.
Peterson surprised many by leaving Tyrrell to return to John Player Team Lotus for 1978.
He won the 1978 South African Grand Prix, with a last-lap victory over Patrick Depailler, as well as the Austrian Grand Prix, in the innovative 'ground effect' Lotus 79. His teammate Mario Andretti won the Drivers' Championship with Peterson acting effectively as the Team "No. 2" with the pair scoring four 1–2 wins, all with Andretti at the lead. Both of Peterson's wins occurred when Andretti encountered trouble, with Andretti winning once when Peterson failed to finish (not including the Italian Grand Prix). Many times, Peterson followed Andretti closely home, leading to speculation that team orders were in place.
Throughout the 1970s, Peterson had the reputation of being the fastest driver in F1 in terms of raw speed. During the 1978 season, Andretti would frequently post the faster qualifying time. Another view, held by some contemporary observers, was that while Peterson may have in fact been the outright quicker of the two, it was Andretti's considerable car development skills that brought the recalcitrant Lotus 78 and 79 to full potential, and Peterson's seeming deference to Andretti was a tacit acknowledgement of this. Despite this, Peterson was offered a seat at McLaren in 1979. Peterson refused to contribute to any controversy, and on numerous occasions dismissed the speculation by stating that Andretti had simply turned the faster time.
The 1978 Italian Grand Prix at Monza started badly for Peterson. In practice he damaged his Lotus 79 race car beyond immediate repair and bruised his legs in the process. Team Lotus had a spare 79, but it had been built for Andretti, and the much taller Peterson did not fit comfortably inside. The team's only other car was a type 78, the previous year's car, which had been dragged around the F1 circuit that season with minimal maintenance.
