German Grand Prix winner Mark Webber will stay on with Red Bull Racing for the 2010 season after agreeing a new deal with the team.
The Australian joined Red Bull from Williams in 2007, having previously raced for the squad in its Jaguar incarnation, and has benefited from its big leap forward to become a title contender this year - despite breaking his leg and shoulder in a winter cycling accident.
"I'm delighted that we have re-signed Mark for 2010," said team boss Christian Horner.
"He has continued to show huge commitment and determination this season, especially following his bike accident at the end of last year.
"His recent results show he is on the form of his life - most notably with his recent win at the German GP - and he has the motivation to deliver at the highest level. It was therefore a straightforward decision to extend the relationship.
"We believe that the driver line-up of Mark and Sebastian [Vettel] is one of the strongest in the sport."
Webber said he had always been keen to remain with the team, and hopes he can carry his current strong form into 2010.
"I'm extremely happy that Red Bull and I have been able to agree to race together again next year," he said.
"Even in the leaner and tougher years at the start of my relationship with the team, I've always enjoyed working with them, so now to go through this purple patch, which we hope will continue for a good while to come, makes the work even more enjoyable.
"We've got a very exciting finish to this year's championship, but I'm also looking forward to helping to develop and race the RB6 in the 2010 world championship."
