San Marino GP 1986

San Marino GP, 1986

Two weeks after the dramatic finish at Jerez, where Ayrton Senna beat Nigel Mansell by the tiniest of margins. The F1 teams were in action again in Spain. The field had been bolstered by a second Zakspeed for Huub Rothengatter but otherwise was the same as before although Alan Jones finally had the first of the new Ford turbocharged engines in his Beatrice Lola.

Ayrton Senna (Lotus-Renault) was on pole ahead of the two Williams-Hondas of Nelson Piquet and Nigel Mansell. The McLaren of Alain Prost was ahead of Michele Alboreto's Ferrari with Keke Rosberg (McLaren), Stefan Johansson (Ferrari) and the Ligier-Renault of Rene Arnoux next up. The top 10 was completed by the Benetton-BMWs of Gerhard Berger and Teo Fabi while Patrick Tambay was 11th in his Lola-Hart.

Piquet took the lead at the start with Piquet behind him but Mansell had an engine problem and dropped back behind Prost and Rosberg. On the fourth lap Prost and Rosberg both overtook Senna but then Rosberg passed his team mate to take second place. Alboreto was fourth while Senna disappeared with a wheelbearing failure. This meant that Fabi and Berger were fifth and sixth, although the Austrian soon overtook the Italian.

During the pit stops Prost's crew did a better job and he took the lead when Rosberg pitted on lap 33. Keke's stop was slow and he rejoined second. The order then settled with Piquet having to watch his mirrors for Alboreto while he conserved fuel. Finally he had enough fuel to race again. Alboreto faded and disappeared later with a turbo problem. Piquet caught Rosberg but the McLaren seemed to be able to hold him off until Rosberg ran out of petrol. Riccardo Patrese, up to fourth in his Brabham, also stopped and this meant that Gerhard Berger found himself in third at the finish behind Prost and Piquet. Johansson was fourth with Rosberg and Patrese classified fifth and sixth.
