The1986 San Marino Grand Prix was aFormula Onemotor race held atImola on 27 April 1986. The race was the third round of the year's World Championship. As withthe previous year's event, fuel consumption was a big issue, changing the points finishers in the closing laps.
The Autodromo Dino Ferrari had received safety upgrades from the previous year, including slight track modifications after the Variante Alta chicane and extended runoff areas at the Rivazza complex.
Alain Prost (McLaren-TAG) dominated the race afterAyrton Senna (Lotus-Renault) and Nigel Mansell (Williams-Honda) 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 (hisMcLaren teammateKeke Rosberg was classified 5th despite running dry 2 laps from the finish, a problem attributed to Rosberg using too much boost).Nelson Piquet brought his Williams home in second place only 7.645 seconds behind Prost, whileAustrianGerhard Berger finished third to score his and theBenetton team's first Formula One podium finish.
This race saw the long awaited debut ofFord's replacement for the oldCosworth DFV in the form of a new 900 bhp (671 kW; 912 PS),turbochargedV6engine designed byKeith Duckworth who had also designed the DFV. In its debut race in the also newLola THL2 and driven by1980 World ChampionAlan Jones, the newCosworth built Ford qualified in 21st place and completed 28 laps in the race before Jones was forced to retire with overheating.
