World championship leader Sebastian Vettel took pole position Saturday for the Formula One Singapore Grand Prix as he attempts to seal back-to-back titles.

The Red Bull driver clinched his 11th pole of the season - becoming the sixth man in F1 history to achieve that feat - by setting a time more than three tenths of a second faster than his teammate Mark Webber.

The McLaren pair Jenson Button and Lewis Hamilton were third and fourth fastest around the Marina Bay circuit ahead of the Ferrari pair of Fernando Alonso and Felipe Massa.

Michael Schumacher and Nico Rosberg of Mercedes qualified seventh and eight respectively for Sunday's street circuit race, and Force India's Adrian Sutil and Paul di Resta will start ninth and 10th.
