LONDON - Formula One world champion Sebastian Vettel extended his contract with Red Bull until the end of the 2014 season on Monday.

The 23-year-old German finished ahead of Ferrari driver Fernando Alonso and Red Bull teammate Mark Webber in the 2010 championship, the AP said.

Vettel, who became the youngest driver to win a F1 race at 21, also helped his team win the constructors' championship.

The new season begins with the Australian Grand Prix in Melbourne on March 27.
