Rain, which was already falling at the start of the race, continued and got heavier. Near lap 30, Mauro Baldi spun out and ended on track with damage to his car and leaving a lot of mud on the racing surface, and Alain Prost retired with damage after spinning and striking the rear of his car on the track barrier. Still in the lead, Ayrton Senna signaled to race officials along pit lane asking them to stop the race. The race was not stopped or interrupted, but did continue at an unusually slow pace because of the poor weather conditions. The 1985 Portuguese Grand Prix was originally scheduled for 70 laps. At the beginning of lap 67, race leader Ayrton Senna was given a "one lap to go" indication from the race director, as the race had exceeded the prescribed two-hour time limit. Senna crossed the line, having led every lap of the race, and with only one other car on the lead lap, that of second-place Michele Alboreto. Patrick Tambay and Elio de Angelis, both one lap down, took third and fourth. Nigel Mansell and Stefan Bellof took the final points-paying positions, two laps down. Senna's win was his first of two in the 1985 Formula One season, and the first of what would be 41 Formula One Grand Prix victories. Classification Qualifying Source: ChicaneF1.com.
