Jenson Button was basking in the glory of another successful qualifying session at the Malaysia Grand Prix in Sepang.

The Brawn GP driver grabbed pole position for the second time in as many weeks.

Having claimed victory in Australia last week after starting from the front, the Englishman proved the class of the field once again as he clocked a time of one minute 35.181 seconds on his final lap of the session.

Jarno Trulli will line up alongside Button on the front row of the grid for Toyota after finishing second, 0.092 secs behind the pole sitter.

Despite recording only the fifth best time in final qualifying, Timo Glock will be third in the second Toyota as a result of penalties handed out to Red Bull's Sebastian Vettel and Brawn GP's Rubens Barrichello, who had the third and fourth best times in the session respectively.

Nico Rosberg will start fourth for Williams, with Mark Webber's Red Bull fifth and Robert Kubica's BMW sixth.

Kimi Raikkonen's Ferrari is seventh while the Renault of two-time world champion Fernando Alonso is eighth.

Following his disqualification from last week's Australian Grand Prix, Lewis Hamilton's miserable week continued with the world champion due to start 12th after failing to get past the second segment of qualifying.

But the biggest surprise was Felipe Massa, who will start 16th after his Ferrari failed to get past Q1.

The day though belonged to Button as he picked the right time once again to put in a hot lap.

He did little to impress during final practice this afternoon and the first stint of qualifying but gave a hint of what was to come by posting the fastest lap of 1:33.784 in Q2.

Button trailed behind team-mate Barrichello in the closing stages of Q3 but jumped to the front with his last lap of the day.

His pole position was confirmed when Trulli finished just under one tenth of a second behind the Brawn GP shortly afterwards.

It is the fifth pole of Button's career but the first time that he has achieved it in consecutive races.

"This one is probably more special than in Melbourne because it is not easy get one pole position but to have two on the trot, I've never achieved that in my F1 career," said the 29-year-old.

"This is a great feeling and it shows that the car works on different types of circuits. I expected the competition to be pretty tough here but qualifying was okay for us."

Button was unhappy with the handling of his car in practice on Friday but overnight adjustments rectified any problems he might have felt.

"Yesterday I was really struggling with the balance of the car. I had a lot of rear locking and instability, which is not really my forte really because I find it difficult to drive it around," he explained.

"So we changed it around overnight and it's improved it a lot and I feel very comfortable in the car, so it makes it very exciting for tomorrow.

"It's a big change from what we expected. Looking at yesterday's times, the Ferrari seemed to be the quickest car, so it is a big turnaround today and I'm quite happy with that."

Having displayed the competitiveness of his Toyota, Trulli will be hoping to crash Button's parade tomorrow.

"I hope to have a good race and a good fight because it is what we are looking for. Hopefully, it will be a nice race," said the Italian.

"I didn't expect to be here today because yesterday I was struggling. Like Jenson, I wasn't really comfortable but we got a really good set-up. We looked at the data with the engineers and today in qualifying the car was spot on.

"It's a shame to lose the pole by just a few hundredths but that's the way it is and let's see what happens tomorrow."

Vettel was third quickest but will start 13th after being penalised 10 places for causing an accident involving Kubica in Melbourne.

"We have the penalty and there's nothing I can do, so the key thing is to focus on what we're here for. We're here to race," said the German.

"It's good to see the car performing at such a good level through Q1, Q2 and Q3 but it's a shame I have to drop 10 places tomorrow. I think it will be a very tough day for me tomorrow but I'm looking forward."

However, the most disappointed driver at Sepang was Massa, who was left to rue a strategic error that saw him run only two flying laps in his Ferrari during the first segment of qualifying.

That decision proved costly as the Brazilian was bumped out of the top 15 in the closing seconds of Q1, causing him to miss out on the final two qualifying periods.

"The team thought that it would be enough to be in the top 15 and maybe I thought so as well, to be honest, because when I got back to the pits I was fourth," he said.

"I stayed in the top seven for a while but when I started to drop, it was impossible to go out again because there was no time to do another lap.

"We thought we had enough to get into the top 15 but it wasn't, so we dropped completely."
