Sebastian Vettel pulled out another stunning lap to ensure his 100 per cent pole position record continued through four rounds of the 2011 F1 season at Istanbul Park.

The German had some tough benchmarks to aim at, after Red Bull team-mate Mark Webber and McLaren rival Lewis Hamilton both set laps in the mid-1min 25s, but Vettel belied the fact that he had missed much of Friday's running to blitz a 1min 25.049secs effort that left the rest of the field reeling. While almost everyone else felt the need to try and respond, Vettel climbed form the cockpit of his RB7 and watched.

Webber also dismounted, leaving the stage open to McLaren and Mercedes, the latter having yet to show its hand in the final phase. Despite the promise shown by both Nico Rosberg and Michael Schumacher in free practice, the Silver Arrows were to take third and eighth respectively, with Hamilton unable to depose Rosberg on his final flying lap. The Briton will start from fourth, two places ahead of team-mate Jenson Button, who appeared to back off on his final lap.

Vitaly Petrov will line up inside Schumacher on row four, with Nick Heidfeld and Felipe Massa completing the top ten after the Brazilian did not contest the session in order to save tyres having wasted a set in guaranteeing his spot in Q2.
