Stefan Johansson
Stefan Johansson was becoming something of a Formula 1 supersub by the time he was summoned to Maranello in April 1985. The previous year, he'd proved capable of outqualifying Stefan Bellof at Tyrrell while filling in for the injured Martin Brundle, and had starred for Toleman in replacing alternately Ayrton Senna (a row over his move to Lotus for 1985) and Johnny Cecotto (injured).
He'd even contested the season-opening 1985 Brazilian Grand Prix in place of Bellof, whose management was in a dispute with Tyrrell.
(Even though he was entered in a Toleman as well but they arrived with no tyre contract.)
In fact after the Brazilan GP he suddenly found himself to have become a Ferrari driver.... replacing the suddenly sacked Arnoux.
Interestingly at the following Portugese GP Stefan was again double entered in both a Toleman and a Ferrari (he actually drove for Ferrari)
Stefan in the Tyrrell-Ford for the 1984 British Grand Prix at Brands Hatch (he was DSQ'd)
Stefan in the Tyrrell at the 1985 Brazilian GP.
IAs mentioned he was entered for that race in a Toleman. Unfortunately they had no tyre contract and were unable to race on raceday.
I think this is Stefan testing the unsponsored Toleman in 1985 pre season.
Stefan also drove for AGS at the 1991 USGP at Phoenix. He DNQ'd
He also drove 4 races in 1991 for Footwork, here at the Canadian GP (Footwork-Porsche V12, FA12) He retired with engine failure whilst running 13th.. (the other 3 races he DNQ'd)
