Qualifying
Alain Prost took his first pole position for McLaren with a time of 1:22.661, just ahead of the Lotus - Renault of Nigel Mansell . Prost's pole was also the first pole for the McLaren MP4/2 as well as for the TAG - Porsche engine. Stefan Bellof was the only non-turbo qualifier in his Tyrrell - Cosworth . Bellof qualified 20th and last while Brundle's crash behind the pits at Tabac saw him as a spectator for the race. Bellof's time edged the Arrows - Ford of Marc Surer by just 0.156. The turbo ca...
BMW had built specially detuned engines for Brabham to use at Monaco. Instead of the normal 900 bhp (671 kW; 912 PS) engines, the Brabhams only had around 700 bhp (522 kW; 710 PS) to play with, the theory being that full power was not needed at Monaco and the detuned engines would be more drivable. It was also an attempt at better reliability as the team had yet to score a point for the year. Never at ease at Monaco, reigning World Champion Nelson Piquet qualified 9th. With Teo Fabi having commi...

Prost was passed on lap nine by Nigel Mansell , to lead a Grand Prix for the first time, when Prost's TAG engine was misfiring and he was delayed by both Corrado Fabi 's stalled Brabham and Michele Alboreto 's about-to-be-lapped Ferrari just before the tunnel (Prost actually hit a marshal who was pushing Fabi's car away but with no serious injury). [ citation needed ] Mansell pulled away from Prost at around two seconds per lap, before going off six laps later on the run up to Casino Square afte...
Lauda disposed of Arnoux but Prost assumed the lead again, only to have the Toleman - Hart of Ayrton Senna , who had also passed the Ferrari, quickly closing in. Senna had started thirteenth in the generally uncompetitive Toleman , in the first Formula One street race in his rookie season, and was showing his wet weather skills that would become legendary. [ 3 ] On lap 29, Prost waved to the stewards of the race to indicate that he felt the race should be stopped. He was also suffering from a ma...
Race
This was the first time that Ayrton Senna had set a Formula One fastest lap. It was also Toleman's second and final fastest lap in Formula One (Derek Warwick had set the team's only other fastest lap during the 1982 Dutch Grand Prix at Zandvoort ).
