Coulthard wants to race for RBR in 07

Coulthard won all of his thirteen Grands Prix in Newey-designed cars - initially at Williams and then at McLaren, where he raced for nine seasons before joining Red Bull last year.

And the Scot said he has no wish to retire in the near future, adding that Newey is now his primary motivation to continue racing.

"I'm stuck on 13 wins, which is a horrible number," Coulthard said at the Autosport International Show, in front of a packed crowd. "Obviously if I hadn't moved over a couple of times then I would have had more.

"But I'd like to add a 14th, and as you say all my victories have been in Adrian's cars, and the motivation is to be in a 2007 car which he has played his part in [designing], and so I need to get my finger out and try to do a good job this year."

Coulthard also downplayed recent speculations that he is likely to hang up his helmet and turn to management soon, stating he has no inclination to think about his life after racing.

"I haven't considered it because it means thinking about it, and thinking about it means thinking about retiring," he replied when asked if he would switch to a managerial role.

"I think about the testing at Barcelona next week; I think about racing at Monte Carlo...I just think about the year ahead.

"You know, I don't think [Fernando] Alonso or Kimi Raikkonen think what they're going to do after they retire from F1, and so I have to be of the same mindset if I want to achieve anything."
