ピエルルイジ・マルティニ
Toleman entered two cars again for the Italian Grand Prix at Monza, but local driver Pierluigi Martini - deputising for Cecotto - failed to qualify for the race. In Senna's car was Stefan Johansson, who qualified 17th fastest and finished in 4th place. When Senna returned after his "penalty", he and Johansson finished the season together.
