Sebastian Vettel's 2011 qualifying tally now stands at seven poles from eight grands prix, as the world champion took his 22nd Formula 1 career pole in Valencia.
The German leads an all-Red Bull front row ahead of team-mate Mark Webber, who was only fifth after the first Q3 runs, but was the only man to improve at the second attempt and duly jumped to second.
Lewis Hamilton completes the top three in the best McLaren, ahead of the Ferraris of Fernando Alonso and Felipe Massa. Montreal winner Jenson Button (McLaren) will start sixth.
The Mercedes chose to only make one Q3 run and filled row four, with Nico Rosberg a scant 0.009 seconds ahead of team-mate Michael Schumacher.
Fifth row men Nick Heidfeld (Renault) and Adrian Sutil (Force India) both made the Q3 cut but did not set times - Sutil sitting the session out, and Heidfeld going out briefly at the end before aborting his run.
Sutil's last-minute progress into Q3 came at the expense of Renault's Vitaly Petrov - which was the only real upset of the first two thirds of qualifying.
Paul di Resta joined the Russian on row six in the second Force India, ahead of Rubens Barrichello (Williams) and Kamui Kobayashi (Sauber).
The second Williams of Pastor Maldonado caused a brief red flag in Q2 when it ground to a halt in the middle of the track. But he had already done a time good enough to secure 15th on the grid ahead of Sauber's Sergio Perez and Toro Rosso's Sebastien Buemi.
After some fleeting scares for Webber, Kobayashi and Massa (who got himself out of danger by sticking on soft tyres and blasting to the Q1 top spot by a huge margin), it was Toro Rosso's Jaime Alguersuari who was again the upper midfield driver exiting in Q1. He ended up 18th ahead of the Lotus duo - Heikki Kovalainen in front of Jarno Trulli, who spun on his final Q1 run.
Everyone comfortably made the 107 per cent qualifying cut, with Tonio Liuzzi's Hispania splitting the Virgins as he edged ahead of Jerome D'Ambrosio.
