Sebastian Vettel claimed his eleventh pole of the 2011 F1 season and maintained Red Bull's unbeaten run by claiming top spot in qualifying for the Singapore Grand Prix - despite having to abort his second flying run.
The German's first effort was good enough to claim P1 after the top five runners had completed their initial flying laps, and none of his rivals proved sufficiently fast to dislodge him, despite several improvements.
Mark Webber improved the most, leaping into P2 to confirm another all-RBR front row, while Jenson Button also gained, by moving into third spot at the expense of McLaren team-mate Lewis Hamilton, whose Q2 puncture may have prompted the team not to waste another set in pursuit of a pole that appeared well out of reach. The Briton only dropped to the outside of row two, however, as Fernando Alonso's final run also failed to yield an improvement.
The two-by-two appearance of the grid continues on row three, where the Spaniard was joined by Felipe Massa, who had had to abort his first run after seeing his concentration thrown by Hamilton attempting to muscle through on the warm-up lap. The Brazilian did enough on his remaining run, however, to see off the challenge of Mercedes' Nico Rosberg, who will line up alongside team-mate Michael Schumacher on row four as neither Force India driver ventured out, also as a consequence of having to use extra sets of tyres to make it as far as the final phase.
