The 1985 Portuguese Grand Prix was a Formula One motor race held in Estoril on April 21, 1985. It was the second round of the 1985 FIA Formula One World Championship and was won by Ayrton Senna from pole position, taking both his first pole position and win in the process. Senna demonstrated his proficiency in wet conditions by finishing the race at least one lap ahead of every car except second-place finisher Michele Alboreto.
Jonathan Palmer was the first driver to retire, and was able to bring his Zakspeed into the pits and retire with suspension problems. Wet weather caused spinouts frequently early in the race. Philippe Alliot retired trackside for this reason on lap 3. François Hesnault retired trackside with an electrical problem on the same lap.
On lap 4, Riccardo Patrese made contact with Stefan Johansen while attempting to pass him on the inside line. Running 10th and 11th at the time, both cars were spun out into a gravel trap by the contact. Patrese was beached, and Johansen was able to rejoin the race after a delay, several positions down. Soon after, Stefan Bellof and Manfred Winkelhock made contact on track; both were able to restart their cars and rejoin the race. Numerous other small offs and spinoffs continued through the wet conditions.
By lap 10, Ayrton Senna had pulled away from 2nd position by almost 13 seconds. Elio de Angelis, Alain Prost, and Michele Alboreto (in order) were closely contending second position, and Derek Warwick was 15 seconds behind them in 5th. Gerhard Berger and Pierluigi Martini both spun off and retired on lap 12. The top four held steady to lap 15, with Niki Lauda and Patrick Tambay in 5th and 6th, 25 seconds behind 4th place Alboreto. Keke Rosberg spun his car on track on lap 16 and it came to rest in the middle of the track, causing a local yellow. Rosberg's car was not immediately cleared, and remained on track in the same position for numerous laps.
