1990 Mexican Grand Prix

The 1990 Mexican Grand Prix, otherwise known as the XIV Gran Premio de México, was the sixth round of the FIA Formula One World Championship staged at the Autódromo Hermanos Rodríguez in Mexico City, Mexico, on the 24 June 1990.'Mexican GP, 1989', grandprix.com, (Inside F1 Inc., 2015), http://www.grandprix.com/gpe/rr490.html, (Accessed 28/06/2019) The race would be remembered for a dramatic puncture for Championship leader Ayrton Senna in the closing stages, which ultimately handed victory to Alain Prost.
Qualifying saw Gerhard Berger claim a sixth straight pole position for , while Riccardo Patrese grabbed second for . That left Championship leader Senna in third ahead of Nigel Mansell, while Prost was a lowly thirteenth having focused on race pace.
Raceday would not get underway in particularly clean fashion, with the morning warm-up session interrupted by a stray dog. Fortunately there would be no "groundhog" style incidents as there had been in Canada, meaning there were no late changes to the field due to dog related collisions.
The start of the race would see Patrese streak into a surprise lead, with a poor start from Berger leaving him in third behind Senna. They were chased by Mansell and Thierry Boutsen, while Nelson Piquet made a strong start to challenge those two during the opening lap.
Senna eased into the lead at the end of the first lap, with Berger following him past Patrese's Williams with an identical move a lap later. The two McLaren-Hondas duly eased ahead of the Italian's Williams, which was to slip behind a charging Piquet, with Berger working hard to remain on his teammate's tail.
Unfortunately for Berger his pushing would prove fatal to his front left tyre, with a slow puncture forcing him to abandon second on lap 13. He subsequently rejoined in twelfth as Piquet inherited second, although neither the Brazilian, nor the Austrian, were the men to watch.
Indeed, the two s were getting stronger as the race wore on, with Nigel Mansell and Prost beginning to ominously draw onto the back of the two Williams-Renaults in third and fourth. The two scarlet cars duly swept past the two yellow-blue-white cars within the space of nine laps, before sweeping past Piquet's multi-coloured a few laps later.
The second half of the race would see the Ferraris slowly close onto the back of Senna, who would also pickup a slow puncture in the closing stages. In the midst of their mutual chase Prost would scythe past teammate Mansell to secure second, just in time to inherit the lead when Senna's tyre spectacularly failed, with the McLaren picking up too much additional damage to continue.
Prost was therefore left to claim his second win of the season, while a late spin for Mansell almost let a charging Berger secure second, only for the Brit to throw a very ambitious lunge at the Austrian through the Peraltada. Berger was hence forced to drop back to third rather than have a huge accident with the Ferrari, as Alessandro Nannini, Boutsen and Piquet the other scorers.
==Background==
Ayrton Senna had once again extended his Championship lead with victory in Canada, moving a full twelve points clear of teammate Gerhard Berger in second. The Austrian himself had a fairly healthy gap back to Alain Prost in third, five points separating them, while Jean Alesi was hanging on in fourth, a point behind Prost. Nelson Piquet, meanwhile, would move up to fifth after his podium finish, while Derek Warwick had become the fourteenth scorer of the season.
In the Constructors Championship it was still an all affair, with the Anglo-Japanese squad reaching a half-century with three wins from five races. had moved up to be their closest competitors, although the Scuderia were already 29 points behind with a third of the season gone. , meanwhile, had lost ground having slipped to third, while were finally on the board after a miserable start to the season for the former Champion constructors.
