Brawn GP's Jenson Button won the Turkish Grand Prix in his sixth victory in seven Formula One races
Button overtook pole sitter Sebastian Vettel on the first lap following a mistake by the Red Bull driver and held on for a 6.7 second win over Red Bull's Mark Webber.
Vettel touched the grass around turn 10 to veer wide, providing Button with an opening to pass.
Vettel, the only other race winner this season, finished third.
"(It's) the first race where the car has been absolutely perfect," Button said. "This car is just outrageous. Before this, I really believed the Red Bulls were on our pace, but today we were a step ahead."
Button's fourth straight win is the best streak by a Briton for 17 years.
Webber overtook Vettel after his final stop and held his teammate off by 0.7 seconds for his second runner-up finish this season.
Lewis Hamilton, the defending F1 champion, finished 13th.
McLaren has now gone eight races without finishing in the top three.
