The German led throughout from pole position to finish 1.7 seconds ahead of fast-finishing McLaren driver Jenson Button, with Red Bull’s Mark Webber third.
Vettel leads the drivers’ championship by 124 points with five races left and is virtually certain to take back-to-back titles. To prevent that happening, second-placed Button would need to win every race while Vettel fails to gain any points.
“In the heat we kept our heads cool, and it was a perfect day,” Vettel said.
