Imola 1985 - When Prost was too light to win

On this day in 1985, the San Marino Grand Prix ended in confusion with drivers appearing on the podium but ultimately not on the right step.

Initially branded the winner, McLaren's Alain Prost was disqualified two hours after the race ended when his car was found to be two kilos underweight.

Ayrton Senna had led for most of the race but the Lotus driver ran out of fuel four laps from the end, as did Ferrari's Stefan Johansson who came within three laps of winning his first Grand Prix.

The stewards eventually awarded the win to second-placed man Elio de Angelis, while Thierry Boutsen - who had to push his car across the finish line - went from third to runner-up, with Patrick Tambay completing the top-three.

We have no idea what Mr. Lauda was doing up there in the melee.
