Trulli heads all-Toyota front row

The result was Toyota's first pole since the 2005 Japanese GP, and came after increasingly impressive progress from the team in the opening rounds of the season.

Trulli and Glock held first and second after the early runs of Q3, and although Jenson Button (Brawn) and Lewis Hamilton (McLaren) briefly pushed them down the order - fleetingly making it an all-British front row - the Toyota duo moved back to the top with their final runs.

Pole ultimately went to Trulli by 0.3 seconds, with his team-mate Glock enjoying the same margin back to third-placed Sebastian Vettel, whose excellent qualifying form for Red Bull continued.

Championship leader Button had to settle for fourth, ahead of Hamilton and Rubens Barrichello in the second Brawn.

Fernando Alonso claimed seventh for Renault, with the Ferraris in eighth and 10th - Felipe Massa and Kimi Raikkonen split by Williams's Nico Rosberg.

Hamilton's progress actually knocked his McLaren team-mate Heikki Kovalainen outside the Q3 cut-off, leaving him 11th, alongside Kazuki Nakajima, who was closer to Williams team-mate Rosberg than at recent races but still not quick enough for the top ten.

The BMWs will share row seven after another disappointing performance, while Renault's Nelson Piquet finally reached Q2 for the first time in 2009, only for his error at the final corner to leave him 15th.

Last week's third-place qualifier and second place finisher Mark Webber is set to start from the back row of the grid in Bahrain - but through no fault of his own.

The Red Bull was on course to easily make the Q2 cut when Webber was impeded by Adrian Sutil's at the entry to the final corner, leaving the Australian in the bottom quarter of the grid along with the Force Indias and Toro Rossos.

Sutil managed a season-best 16th, although this will be in jeopardy if the stewards opt to issue any penalties over the Webber incident.
