In Formula One he participated in 103 Grands Prix, debuting on 13 January 1980 for the Shadow Racing Team at the 1980 Argentine Grand Prix when he was still a Formula Three regular. He failed to qualify for the race and the next race in Brazil and he was not seen in Formula One again until 1983, after spending 1982 in the European Formula Two Championship with Spirit Racing, where he finished eighth overall, his best finish being third at Mugello in Italy.
Spirit (1983)
Johansson's first Formula One race with Spirit was at the non-championship 1983 Race of Champions at Brands Hatch, where he failed to finish due to failure of the Honda engine on lap four. His qualifying time was almost 20 seconds off the pole time set by 1982 World Champion Keke Rosberg in his Williams-Cosworth, but his times in the race morning warm-up session were within a second of the Ferrari 126C2B of René Arnoux, who was fastest. He moved up to seventh place before pulling into the pits with another engine failure. Anecdotally, then-BBC commentator Murray Walker said on air that Spirit and Honda had completed thousands of miles of trouble-free testing until that point. Spirit continued to test and develop the 201C and Johansson re-entered Formula One at the 1983 British Grand Prix at Silverstone where he qualified the car in a credible 14th position. He raced in a further five Grands Prix in 1983, with a best finish of seventh in the Dutch Grand Prix at Zandvoort.
Tyrrell/Toleman (1984)
Stefan Johansson was replaced at Spirit by Mauro Baldi for the 1984 season when the team lost its Honda engines to Williams and he didn't race until he joined Tyrrell in Round 10 of the championship, the British Grand Prix at Brands Hatch, as a replacement for the injured Martin Brundle. He then went on to drive for Toleman for the last few Grands Prix of the season in place of the injured Johnny Cecotto, finishing fourth in the Italian Grand Prix at Monza. While at Toleman, Johansson's regular teammate was future triple World Drivers' Champion Ayrton Senna.
Ferrari (1985–1986)
Johansson signed a contract with Toleman for 1985 but it fell through when Toleman failed to secure a tyre agreement. Instead Johansson started again with Tyrrell as a replacement for the suspended Stefan Bellof before being called up to Ferrari when René Arnoux was mysteriously sacked after the first race of the season in Brazil. At his second race with Ferrari, namely their 'home' race, the San Marino Grand Prix, two laps from home he passed Senna's out-of-fuel Lotus to take the lead to the delight of the Tifosi, and would probably have won if his Ferrari 156/85 had not run out of fuel itself just half a lap later. His role at Ferrari for the 1985 season was primarily to support Michele Alboreto's championship challenge, though he did finish second to the Italian at Canada, and backed it up with second in the next race at Detroit.
In 1986, he often outpaced Alboreto, despite the Italian being the team's lead driver. The V6 turbo in the Ferrari F1/86 lacked nothing in power compared to the Honda, BMW, Renault and TAG-Porsche engines, but the car itself proved to be difficult, with both drivers complaining through the season about lack of downforce and the car's reluctance to drive well on all but the smoothest of circuits. Johansson finished fifth in the 1986 Drivers' Championship, his best-ever position, while Alboreto, who finished second in 1985, could only manage ninth place. There were many in Formula One, including highly respected then-BBC commentators Murray Walker and 1976 World Champion James Hunt, who believed that Ferrari were sacking the wrong driver, given that the Swede had generally outshone his more highly-paid teammate throughout the season.
McLaren (1987)
He was replaced at Ferrari by AustrianGerhard Berger for 1987 and he moved to McLaren as number two driver behind double and reigning World Champion Alain Prost. McLaren weren't as competitive in 1987 as they had been in 1984–1986, with Prost only adding three wins to his tally (and beating the record of 27 Grand Prix wins held by Jackie Stewart with his 28th win in Portugal) and failing to successfully defend his Drivers' Championship. Further podium finishes did follow for the Swede and Johansson finished sixth in the Drivers' Championship. Stefan Johansson's position at McLaren was considered by many as just a stop gap signing by team boss Ron Dennis who had failed to lure Ayrton Senna from Lotus due to him being under contract until the end of 1987 and always intended signing the Brazilian for 1988.[3] Johansson famously finished the 1987 German Grand Prix on three wheels having had a puncture on the last lap. He also finished second behind Prost in Belgium and added further podium finishes in Brazil, Spain and Japan. Despite 11 podiums in three seasons, Johansson was still winless and was not wanted by a top team (he had hoped to join Williams in 1988 as a replacement for the departing 1987 World Champion Nelson Piquet but Williams signed Riccardo Patrese instead). He did return to McLaren in a test-driver capacity in 1990, testing the Honda V12 engine at Suzuka in Japan and helping with the development of a paddle shifter and a new gearbox.[4]
Ligier (1988)
He joined Ligier for 1988, ironically alongside the man he replaced at Ferrari, René Arnoux, but the team's first non-turbo powered car since 1983, the Michel Beaujon-designed JS31 powered by a naturally aspiratedJuddV8 engine, was totally uncompetitive, scoring no points and often failed to qualify, even against teams with much smaller budgets such as AGS and Rial (the French team's low point of the year was when both Johansson and Arnoux failed to qualify for the French Grand Prix at Paul Ricard in the first weekend of July). Unfortunately for Johansson, he failed to come to grips with the JS31, recording six non-qualifications during the season (compared to Arnoux who only failed to qualify twice). He did record the car's two best finishes of the year though, ninth placings in the opening race of the season in Brazil and the last race in Australia.
Onyx/AGS/Footwork (1989–1991)
Better was to follow in 1989 as he was signed to lead the new Onyx team. The car was temperamental and didn't always qualify, but Johansson finished a surprise and popular third in Portugal for his last (and the team's only) podium finish. He fell out with new team owner Peter Monteverdi in early 1990 and was duly sacked, making further appearances for AGS and Footwork in 1991.
In his 11-year Formula One career, in which he drove for 10 different teams at 103 Grands Prix, Johansson achieved 12 podiums and scored a total of 88 championship points.
CART career
For 1992 he moved over to CARTChampionship Car, winning the Rookie of the Year title with two third places, ahead of Belgium's Éric Bachelart. His first pole came at Portland the next year, but as in Formula One he never won a race. From 1992 to 1996, he started 73 races and had his best season overall in 1994, finishing in 11th. During this time, he competed in the 1993–1995 Indianapolis 500. At the 1996 Molson Indy Toronto race, he was involved in an accident that claimed the life of fellow driver Jeff Krosnoff and track marshal Gary Avrin. After making wheel to wheel contact, Jeff's car hit the barriers and also a tree and lamp post that was too close to the track. Krosnoff died instantly of the injuries sustained from hitting the lamp post.
After retiring from CART at the end of the 1996 season he returned to this type of racing. During 1997 he recorded two major race wins, at the 12 Hours of Sebring driving a Ferrari 333 SP with Andy Evans, Fermín Vélez and Yannick Dalmas. Later in 1997 Johansson also won at Le Mans where he drove a TWR-Porsche WSC-95 for Joest Racing alongside his Ferrari F1 teammate of 1985 and 1986 Michele Alboreto, and young DaneTom Kristensen. For Kristensen it was to be the first of a record (as of 2013) 9 wins in the famous French classic.
During 1998 and 1999, Johansson raced for various sports car teams (like the unreliable Audi R8C Coupé at Le Mans) but in 2000 he started Johansson-Matthews racing with an American businessman called Jim Matthews. They competed in the American Le Mans Series using a Reynard 2KQ prototype. Unfortunately this wasn't a successful vehicle in its original form (though it was later developed into various other successful cars including the Zytek that he later raced) and the partnership dissolved.
In 2001, Johansson campaigned an Audi R8 prototype with backing from Gulf Oil and the assistance of Mike Earle's Arena team. That year he raced in the European Le Mans Series, the American Le Mans Series and at Le Mans itself. His co-drivers were Guy Smith and Patrick Lemarie. At Le Mans Smith was replaced by Tom Coronel.
For 2003, he returned to CART as a team owner, running American Spirit Team Johansson with Jimmy Vasser and Ryan Hunter-Reay as drivers. This was one of many new teams for the 2003 CART season; ironically, Bachelart's Mi-Jack Conquest Racing team was another. The team was under-funded, and although Hunter-Reay scored a fluke win in the wet conditions at Australia, it folded at the end of the season.
After only competing in a couple of celebrity races and occasional outings in the works Zytek in 2004 Johansson returned to full-time racing in 2005 driving the Chip Ganassi run New Century Mortgage sponsored Lexus Riley Daytona Prototype in the American Grand-Am Rolex Sports Car Series. With co-driver Cort Wagner he scored his best finish, a second place, at Mont Tremblant in Canada, they finished the year in fifth place in the championship.
In 2006 as well as the Grand Prix Masters series, Johansson has made occasional appearances in Grand-Am for the Cheever and CITGO teams, and has continued an association with the works Zytek team in the Le Mans Series.
2007 saw Johansson competing in a Highcroft RacingCourage-Acura in the LMP2 class of the American Le Mans Series, sharing with David Brabham. He was due to race a Zytek at Le Mans in 2007, but the team could not rebuild the car in time after a test-day accident, and Johansson made a last minute deal to drive a works Courage.
Johansson took part in the inaugural Speedcar Series in 2008, where luck once again deserted him as the victim of a lot of other drivers' accidents. For 2008 Johansson did not have a full-time sports car drive, but had some outings planned in the Highcroft Acura ARX-01 in the ALMS and a place with the Epsilon Euskadi team at Le Mans.
Outside the cockpit, Johansson has a number of business ventures (including managing several successful drivers such as Scott Dixon) and is a keen artist – he is particularly known for his watch designs. Also, Johansson does expert commentary on Viasat Motor during Formula One races on occasion.
