The 28-year-old Briton led from pole position to the chequered flag, apart from three short pit-stops, as he secured his fourth win at the Hungaroring in sweltering conditions. It was the 22nd win of his career and a success that restored him among the challengers for this year's drivers' championship. Hamilton came home 11 seconds clear of Finn Kimi Raikkonen of Lotus and third-placed defending triple world champion German Sebastian Vettel of Red Bull, who was unable to force his way into second place in the closing laps. Australian Mark Webber finished fourth - from 10th on the grid - in the second Red Bull ahead of two-time champion Spaniard Fernando Alonso of Ferrari and sixth-placed Frenchman Romain Grosjean of Lotus.
