1985 San Marino Grand Prix

The 1985 San Marino Grand Prix was a Formula One motor race held at Imola on May 5, 1985. It was the third round of the 1985 Formula One season. It was the fifth San Marino Grand Prix.

Limited fuel allowances played a big part in the race, as a succession of drivers ran out in the last few laps. Alain Prost (McLaren MP4/2B) took the chequered flag before stopping on the slowing-down lap and being found to be 2 kg underweight in post-race scrutineering, meaning disqualification. Elio de Angelis (Lotus 97T) was initially disqualified for the same reason but was reinstated. Williams driver Nigel Mansell noted that "it wasn't really racing". Stefan Johansson (Ferrari 156/85) drove from 15th to 1st before running out of fuel.

The win was the second of two Grand Prix victories for de Angelis and he finished a lap ahead of the field. It was also the second win of the year for Team Lotus after Ayrton Senna had won the previous race at the Portuguese Grand Prix. Second place was eventually awarded to Belgian driver Thierry Boutsen driving an Arrows A8 with Frenchman Patrick Tambay third in his Renault RE60.
