Button and Barrichello have been team-mates since 2006

It means that 2008 will be Button's sixth year with the team while Barrichello will be entering his third season, having joined in 2006.

Button, 27, said: "I'm excited about the opportunity we have for 2008, although 2007 has been frustrating.

"We've not had the performance to be competitive this year," he admitted.

"But what we do have is a very solid team of people which has been boosted recently by some key new appointments.

"Every team has good times and bad, and I am confident that our recent difficulties are now behind us and that next year looks promising."

Button has only picked up one point this season, while his team-mate has yet to get his name on the drivers' standings.

Barrichello said: "I am delighted to confirm that I am staying with Honda for 2008.

"When I came here in 2006, it was always my intention to develop a long-term relationship and help build a strong team together.

"This year has been tough so far but I believe we are heading in the right direction again.

"Jenson and I have a great relationship together as team-mates and stability will be key as we look forward to the challenge of 2008.

"For now though, we have eight races remaining and that is where our focus lies."
