McLaren's Jenson Button drove a composed race to take second place, ahead of a spirited Nick Heidfeld, who capitalised on a brilliant start to round off the podium places in his Renault.
"Fantastic job. In the heat we kept our heads cool. Thank you," Vettel told his Red Bull team over the team radio after winning his fourth race in a row.
