Red Bull's Mark Webber exited on lap 45 after a brake failure had sent him spinning off the track. That officially ended the Australian's slim championship hopes. He had been running fourth in the early part of the race.

"It's disappointing because it should have been an easy second today," Red Bull team principal Christian Horner said. "It's a shame because (Vettel) drove a really good race and it was a great recovery to finish in fourth."

Hamilton's only headache came early in the race when his KERS power-boost system failed, but after a few laps without it, the problem was soon rectified.

"The race as pretty straightforward for me," the 2008 Formula One champion said. "I was never really under serious pressure. When Vettel was behind me I knew I was five laps longer (fueled) and I just had to keep him behind."

Williams driver Nico RosbergNico Rosberg was running second through the first stint of the race, but crossed the pit road exit lane on his way out after his first stop, and had to serve a drive-through penalty that cost him a chance of any points. He finished 11th.
