Sebastian Vettel won his tenth race this season, handing Red-Bull Renault its second consecutive Constructors’ Championship title.
Vettel pulled out an early lead at the Korean grand prix, after overtaking pole-sitter Lewis Hamilton on the first lap.
A safety-car period caused by Vitaly Petrov colliding with the back of Michael Schumacher’s Mercedes on lap 17, led to the pack bunching up, but a determined drive saw the drivers’ champion finish 12 seconds ahead of Hamilton.
Hamilton fought hard for second position, with Mark Webber’s Red-Bull never more than 1.5 seconds behind.
The pair were side by side for a number of corners on lap 34, with the Australian briefly taking second on the first corner of lap 50.
Hamilton regained position seconds later at turn three, with a bold strategy of using all of his KERS charge and DRS at the same time.
