1986 Canadian Grand Prix

The XXV Grand Prix Labatt du Canada, otherwise known as the 1986 Canadian Grand Prix, was the sixth round of the FIA Formula One World Championship, staged at the Circuit Gilles Villeneuve on the 15 June 1986.'Canadian GP, 1986', grandprix.com, (Inside F1 Inc., 2015), http://www.grandprix.com/gpe/rr426.html, (Accessed 28/03/2019) The race would see Nigel Mansell sweep to victory from pole position, in a race that was to be dictated by fuel consumption.
Indeed, Mansell was the man to beat in qualifying, setting a new circuit record as he beat Ayrton Senna to pole across the two sessions. The Brit's teammate Nelson Piquet was next ahead of Alain Prost, while René Arnoux and Keke Rosberg shared the third row.
Race morning would be marred by a huge accident for Patrick Tambay, which saw the Frenchman sustain injuries to both his feet after a suspension failure. Tambay was hence unable to start, while his was taken away for analysis immediately after the race.
Regardless, Mansell would take the lead at the start of the race, with Senna leading the chase from behind. Indeed, it seemed to be an unusually tame start to the race, with no major accidents or incidents to drastically affect the order.
Mansell quickly established a lead at the head of the field, leaving Senna to defend from Prost, Piquet, Rosberg and Arnoux. The man to watch in this group proved to be Rosberg, who duly pushed his way past Piquet, before securing third after Prost barged past Senna at the hairpin. Indeed, Senna would drop to sixth after being forced to run wide at the hairpin, for Rosberg, Piquet and Arnoux were running nose-to-tail.
Rosberg duly sent his scything past teammate Prost a couple of laps later, and come the end of lap seventeen the Finn had barged his way past Mansell. Yet, after a couple of laps in the lead Rosberg was told to ease his pace and conserve his fuel, allowing Mansell and Prost to close right onto his tail.
On lap 22 the battle for victory was effectively settled, with Mansell sneaking ahead of Rosberg when the Finn got caught in two minds trying to lap Alan Jones. Prost would also make his way past the Finn after Mansell pulled clear, although the Frenchman would subsequently drop to fifth during the pitstops.
Prost would spend the second half of the race fighting his way back up to second, while, at the head of the field, Mansell was able to cruise home to claim his fourth career victory. Behind the second placed Prost came Piquet, who passed Rosberg late on, with the Finn just making it to the line before he ran out of fuel. The remaining points would go to Senna and Arnoux who both lost a lap during the stops.
The results of the race meant that Prost moved back to the top of the title hunt, establishing a two point lead over Mansell and Senna. In contrast, Williams-Honda would move to the top of the Constructors' Championship, holding a three point lead over McLaren-TAG Porsche.
==Background==
Ayrton Senna had moved to the top of the Championship as a result of the Belgian Grand Prix, moving two clear of former leader Alain Prost. A five point gap then followed before Nigel Mansell appeared in third, while Nelson Piquet had lost further ground in fourth. Keke Rosberg was next, the last man in double figures upon arrival in Canada, while Michele Alboreto was up in the top ten after scoring his first points of the campaign in Belgium.
In the Constructors' Championship, meanwhile, it would be a tighter affair landing in Canada, with arriving just a point ahead of . Indeed, it seemed as if those two were equally matched in , although were also potential title contenders just nine off the lead after the first third of the season. , meanwhile, were a fairway back in fourth ahead of the , with the Italian squad having moved back ahead of in Spa.
