1986 San Marino Grand Prix

The 1986 San Marino Grand Prix, officially advertised as the VI Coca Cola Gran Premio di San Marino, was the third round of the FIA Formula One World Championship, staged at the Autodromo Dino Ferrari near Imola, Italy, on the 27 April 1986.'San Marino GP, 1986', grandprix.com, (Inside F1 Inc., 2014), http://www.grandprix.com/gpe/rr423.html, (Accessed 28/03/2019) The race would see Alain Prost secure his first victory of the season, despite effectively running out of fuel three corners from the chequered flag.
Qualifying had resulted in an increasingly predictable pole position for Ayrton Senna, with the Brazilian ace sharing the front row with compatriot Nelson Piquet for the third consecutive race. Nigel Mansell was their closest challenger ahead of Prost, with the grid back up to its full 26 car compliment with the addition of a second .
The start of the race saw Piquet get the jump on his less experienced compatriot, with the #6 sprinting ahead of the #12 . Behind, Mansell's start, and ultimately entire race, was ruined by an engine issue, allowing Prost and Keke Rosberg to jump into third and fourth.
The early stages would see Piquet escape from the attentions of Senna, leaving the younger Brazilian to defend from Prost and Rosberg. They duly slipped past the Lotus racer early on the fourth lap, with Rosberg going on to pass teammate Prost to hunt down Piquet out front.
Senna's race was to end soon after with a wheel bearing failure, an issue that also ended the race of teammate Johnny Dumfries. Out front, meanwhile, Rosberg and Prost would reel in Piquet, with the defending World Champion duly jumping ahead of both Rosberg and Piquet to claim the lead during their respective pit stops.
Rosberg would also jump the Brazilian, who briefly had to defend from Michele Alboreto in the as he saved fuel. However, once he felt that he would have enough to make the end of the race Piquet would sprint off after Rosberg, and duly claimed second late on when the Finn had to conserve his fuel allowance.
For Prost, however, it seemed the race was run, until his TAG Porsche engine spluttered and coughed three corners from the chequered flag. The Frenchman duly began weaving to try and pick-up the last droplets of fuel, with the McLaren subsequently coasting to a stop a few yards on from the finish line.
Unlike the 1985 edition of the San Marino Grand Prix, Prost would get to keep his victory, while Piquet was the only other man on the lead lap in second. Behind them came Gerhard Berger in the new , marking his and the team's first trip to the podium, ahead of Stefan Johansson, Rosberg and Riccardo Patrese.
==Background==
Victory in Spain, combined with a second place in Brazil, had left Ayrton Senna at the top of the Championship hunt arriving in Imola, the Brazilian ace having moved onto fifteen points. Nelson Piquet, winner in Brazil, had dropped to second in Jerez, while Nigel Mansell had leapt into third with his second place. Elsewhere, Jacques Laffite and Alain Prost were level on four points to complete the early top five, with ten drivers in total on the score board.
It was a more confused picture in the Constructors Championship arriving for the San Marino Grand Prix, for and were level on fifteen points at the start of the weekend. Ultimately, it was the team from Ethel, Norfolk, that were deemed ahead, courtesy of Johnny Dumfries' ninth place in Brazil. Behind, defending Champions had moved into fourth in Spain, level with , while and rounded out the scorers list.
