Difficult conditions greeted the teams upon their arrival at the Silverstone Circuit, as parts of the Midlands received a month's rainfall in the space of two days. The torrential rain lasted throughout the weekend, forcing qualifying to be suspended for ninety minutes, before race day dawned clear. The circuit was declared dry, allowing the drivers to start on the tyre compound of their choice, with Alonso on the harder tyre streaking away at the start while Paul di Resta crashed at Aintree on the first lap after making contact with Romain Grosjean. As the leaders settled into a rhythm, Pastor Maldonado and Sergio Pérez collided at Brooklands, prompting an angry response from the Mexican driver. Perez's teammate Kamui Kobayashi also ran into trouble, locking his tyres as he entered his pit box and hitting three members of his pit crew, though none were seriously injured. The race was ultimately decided by the choice of tyre in the first stint as Alonso moved onto the softer option and Webber onto the harder prime for the final phase of the race. Webber caught Alonso with five laps to go, passing him on the Wellington Straight. Webber held on for his second win of the season, with Vettel third and Felipe Massa in fourth, his best result since achieving a podium in South Korea in 2010. The result meant Webber closed to within thirteen points of Alonso's championship lead, with both drivers breaking away from third-placed Vettel. After showing early promise in the wet conditions, McLaren went backwards in the dry, losing second place in the Constructors' Championship to Ferrari and third to Lotus.
