Friday 5 February at 16:01 : Feb.5 (GMM) Mark Webber will do the honours when Red Bull's 2010 car is given its track debut at Jerez next week.

In order to maximise the RB6's factory development time, the Milton Keynes team was absent at Valencia when the winter testing ban lifted this week.

But when the second test kicks off next Wednesday, the new car will hit the Jerez circuit alongside its key 2010 rivals, including Ferrari, McLaren and Mercedes.

It emerges that Australian Webber, 33, will be at the wheel for the opening two days, before Sebastian Vettel concludes the four-day test.

Team boss Christian Horner told the BBC this week that watching Red Bull's 2010 rivals start testing at Valencia did not worry him.

"We have had continuity across all aspects of the team. We follow with interest some of the other developments but we are happy focusing on ourselves," said the Briton.

"I'd be more than happy for others to have the headlines at the moment," Horner added.
