BUDAPEST - Sebastian Vettel's luck changed for the better at the Hungarian Grand Prix on Sunday, where the German driver won to extend his Formula One championship lead over archrival Lewis Hamilton by 14 points heading into the summer break.

Vettel's fourth win of the season came from pole position, on a Hungaroring track where overtaking is notoriously difficult. Yet his 46th career win turned out to be anything but a processional affair.

Even before the start, Vettel felt something was wrong with his steering wheel. It bugged him most of the race, but with his teammate Kimi Raikkonen driving brilliantly behind him to fend off the fast-closing Mercedes, Vettel held on and Ferrari got a 1-2 with Raikkonen second.
