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. 1985–1986 Johansson signed a contract with Toleman for 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 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 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. 1987 He was replaced at Ferrari by Austrian Gerhard Berger for 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
