Button capitalized on an opening lap mistake by pole sitter Sebastian Vettel, as he overtook the Red Bull driver and then never looked back from there to claim his sixth victory in the first seven grand prix this season. He became the only driver in the first five Turkish GP to win from a position other than the pole.

"Today the car was the best it's felt all year," Button said. "We have been quick on other occasions and the car has been a bit loose and hasn't really suited my style, but today the car was immense."

Prior to this season, Button had won only one grand prix in 155 starts, but he is now trouncing the competition with a 26-point lead in the world championship standings, thanks in part to the brilliance of team principal Ross Brawn, who resurrected the former Honda Racing team before the start of the season.

"I'm beginning to run out of superlatives to describe our season," Brawn said.

Button became the first Briton to win four consecutive grand prix since Nigel Mansell did it in his 1992 F1 championship season. Mansell won a record five straight races that year, only to be matched by Germany's Michael Schumacher in 2004.

Red Bull's Mark Webber claimed his second podium position of the season with a runner-up finish.

"I knew the podium was pretty much taken, but it was just a question of whom out of Sebastian and myself would get the second place behind this guy who was on another planet," Webber said.

Vettel rebounded nicely from a disastrous performance two weeks ago in Monaco with a third-place finish.

"I lost the rear and went wide at turn ten over the Astroturf and nearly lost the car and a lot of speed also for the straight, so it was no problem for Jenson to pass me," Vettel said.

Toyota's Jarno Trulli and Nico Rosberg from Williams rounded out the top-five.

Robert Kubica from BMW Sauber and Toyota's Timo Glock finished seventh and eighth, respectively, while Ferrari's Kimi Raikkonen and Fernando Alonso from Renault completed the top-10.

Button's teammate, Rubens Barrichello, suffered his worst performance of the season after finishing 19th. Barrichello, who started third, fell way back in the field after he stalled off the start line. He later made contact with McLaren's Heikki Kovalainen, suffering significant damage to the nose of his car. Barrichello eventually retired, marking the first time a Brawn GP driver was knocked out of an event.

"It was a difficult and immensely frustrating day for me today," Barrichello said. "We had a problem with the clutch at the start which caused the car to go into anti-stall, so I wasn't able to get off the line."

Barrichello joined Force India's Giancarlo Fisichella as the only drivers to retire in the 58-lap event.

Ferrari's Felipe Massa was never a factor in his attempt to win a fourth straight Turkish Grand Prix. Massa ended up with a sixth-place finish. He had won the last three races from the pole at Turkey.

The season woes continued for defending world champion Lewis Hamilton as he finished 13th. The McLaren driver has scored only nine points so far this year.
