Finally, McLaren test driver Emanuele Pirro replaced Johnny Herbert at Benetton after it was decided that Herbert needed more time to recover from the leg and ankle injuries he had sustained in the Formula 3000 race at Brands Hatch in 1988 . Benetton debuted their B189 car, with the new Ford HB engine, at Paul Ricard, Alessandro Nannini driving this car while Pirro drove the older, DFR -powered B188 .

Qualifying
The other entrants who failed to pre-qualify on the Friday morning were Modena's Brabham team-mate Martin Brundle in sixth, the second time in a row the British driver had failed at this stage. Volker Weidler was seventh in the Rial , his seventh successive failure to pre-qualify. Both Zakspeeds again missed out, Bernd Schneider eighth, and Aguri Suzuki eleventh. Ninth was Piercarlo Ghinzani in the second Osella, the Italian's seventh consecutive pre-qualifying failure, and Pierre-Henri Raphanel...
Race
At the first start, Senna led into the first corner from Prost, while behind them, Gugelmin locked his brakes and veered into Boutsen's Williams and Berger's Ferrari. The March launched into the air and flipped upside down, also knocking off Mansell's rear wing. The race was immediately red-flagged, a shaken Gugelmin taking the restart from the pit lane along with Mansell and Donnelly.
Race
Prost took the chequered flag 44 seconds ahead of Mansell, with Patrese a further 22 seconds back. Alesi was fourth, seven seconds behind Patrese and the last driver on the lead lap, with Johansson scoring Onyx's first points in fifth and Olivier Grouillard in the Ligier scoring his only point for sixth. Pirro was ninth, Bernard 11th and Donnelly 12th, while Gugelmin recovered from his accident by setting the fastest race lap.
With the win, Prost extended his lead over Senna in the Drivers' Championship to 11 points.
