Sunday 5th May 1985

Limited fuel allowances played a big part in the San Marino Grand Prix at Imola, 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.
