Row three was formed of Gerhard Berger and Thierry Boutsen; Nigel Mansell lined up seventh alongside the Minardi of Pierluigi Martini, while Emanuele Pirro and Nelson Piquet rounded out the top ten.
At the start there was an overly long delay between the red and green lights, which caused the drivers to be a little more agitated than usual, resulting in an accident between Prost and Berger at the Mirabeau corner.
At the second start everything went to plan and Senna led from Prost, Alesi, Berger, Patrese and Boutsen, with Pirro being the first retirement when his engine blew on the opening lap.
On lap 35, Piquet spun approaching Loewes Hairpin and stalled his engine; he received a push start from the marshals and was disqualified as a result.
First he disposed of Derek Warwick and then managed to successfully pass Boutsen for fourth, as Alesi and Berger fought over second place.
Alesi was second, followed by Berger, Boutsen, Alex Caffi and the only other survivor, Éric Bernard, who had taken sixth place in the late stages after he had forced himself past Gregor Foitek's Onyx by pushing him into the wall.
