Yeongam: Sebastian Vettel won the Korean Grand Prix on Sunday to secure Red Bull`s second successive Formula One constructors` championship.
The 24-year-old German, who clinched his second drivers` title in a row in Japan last weekend, took the lead from McLaren`s Lewis Hamilton on the opening lap and never looked back despite a safety car period bunching up the field.
With three races remaining, and a maximum 129 points to be won, Red Bull have an insurmountable 140 point lead over McLaren.
The victory was Vettel`s 10th of the year, three off Michael Schumacher`s 2004 single season record of 13 with Ferrari, and 20th of his Formula One career.
Hamilton finished second, with Australian Mark Webber third for Red Bull.
