stop on lap 29. Vettel exited the pits behind Webber, with all the leaders due to make one more pit stop. On lap 37, Hamilton was lapped by championship leader Button, who made his second stop along with Webber on lap 43. Vettel briefly ran second but had to make his third pit stop on lap 48, demoting him back to third position. Trulli emerged from the pit stops in fourth, narrowly ahead of Rosberg, while Robert Kubica and Timo Glock had moved into the final points paying positions as Raikkonen struggled and Kazuki Nakajima was delayed by a left front wheel covering failing to attach in his final stop. Meanwhile, Barrichello's miserable race finally ended as he retired with a gearbox problem while running near the back of the field. This was the first time that a Brawn GP car was not running at the finish of a race. Although Vettel closed the gap to Webber to just 0.7 seconds as the chequered flag fell, there were no significant positional changes in the final laps as Button cruised to his sixth win from the first seven races, a feat only matched by Alberto Ascari, Juan Manuel Fangio, Jim Clark and Michael Schumacher – who all won the World Championship after achieving this feat. Button also became the first Englishman to score record four consecutive victories since Nigel Mansell in 1992, who too went on to win the title that season. The race attendance was reported as a meager 36,000, with the venue capable of holding 150,000.
