F1 leader Vettel wins Turkish Grand Prix

Red Bull driver Sebastian Vettel cruised to victory in the Turkish Grand Prix on Sunday, winning ahead of coworker Mark Webber to get bigger his lead in the Formula One standings.

The F1 champion, who has three victories this year, was never in problem at Istanbul Park after starting from the pole for the fourth successive race and winning by a contented 8.8 seconds.

"Throughout this race we had this cushion and were able to act, quite than react," the 23-year-old Vettel said. "We never really had anybody close at the back, which would have been a different situation."

Vettel leads McLaren's Lewis Hamilton by 34 points and Webber by 38.

"I think the day you start to think you are invincible is the day you get beaten, for sure," Vettel said. "There is always someone, at some point, who teaches you a lesson, who gives you a hard time and beats you."

Vettel is even less likely to get approved away after four races, given the championship went down to the final day last year.

"We saw how quickly these things changed last year; it was very close," Vettel said.
