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. He led his second race with Ferrari at their 'home' race, the San Marino Grand Prix, and two laps from home passed Senna's out of fuel Lotus to the delight of the Tifosi and would probably have won if his &lt;a href="Ferrari%20156/85"&gt;Ferrari 156/85&lt;/a&gt; had not run out of fuel itself just half a lap after taking the lead. His role at Ferrari for the 1985 season was primarily to back up 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.
