Mark Webber and Sebastian Vettel locked out the front row for Red Bull in qualifying for the Korean Grand Prix on Saturday.
Webber clocked 1 minute, 37.242 seconds for his the second pole of the season after winning from the front in Monaco.
Last year's race winner Vettel followed seven hundredths of a second back to secure P2 and increase his chances of closing the four-point gap to championship leader Fernando Alonso, who qualified in fourth.
Lewis Hamilton starts in third after posting 1:37.469 in his McLaren, followed by Alonso and Kimi Raikkonen, who trails the Spaniard by 37 points and still has an outside shot at the title.
Alonso's teammate at Ferrari, Felipe Massa, clocked the sixth-fastest time, with Raikkonen's partner Romain Grojean seventh in the Lotus.
The German trio of Nico Hulkenberg, Nico Rosberg and Michael Schumacher round out the top ten.
Russian driver Vitaly Petrov starts 19th after out-qualifying his teammate Heikki Kovalainen, who is 20th.
