Sunday 27th April 1986
The San Marino Grand Prix was held at Imola. As with the previous year’s event, fuel consumption was a big issue, changing the points finishers in the closing laps. Alain Prost driving a McLaren-TAG Porsche MP4/2C dominated the race after Ayrton Senna and Nigel Mansell retired early, before almost running out of fuel, three corners from the chequered flag. Frantically weaving the car back and forth to slosh the last drops of fuel into the pickup, he managed to keep it running just long enough to creep over the line and win the race.
