Mercedes has ended speculation about Nico Rosberg's future by announcing the 26-year-old has extended his contract.
German Rosberg, who was already contracted to race alongside Michael Schumacher next season, has now inked a "multi year" extension to include 2013 "and beyond", the Brackley based team said on Thursday.
"I have every confidence that the team will provide me with a winning car," said Rosberg, who was recently linked with a switch to Ferrari.
Added team boss Ross Brawn: "We know that he is a driver who can win races and championships."
It was reported in the German press on Wednesday that Schumacher is also set to extend his current contract to include 2013.
"In Michael, Nico has the most successful racing driver in the history of the sport as his teammate, which is a perfect combination for him as well as for our team," said Mercedes-Benz's Norbert Haug on Thursday.
