Coulthard to stay at Red Bull

David Coulthard is determined to stay at his Red Bull team beyond the end of this season to benefit from the arrival of ex-McLaren designer Adrian Newey. The Scot, 34, told BBC Sport: "Adrian's hand has been part of cars that have won more than 100 Grands Prix.

"The evidence would be that if you give him the resources and support then he will give you a competitive package."

"My motivation is to be in an Adrian-influenced Red Bull in 2007," Coulthard said.

"Obviously the success of teams Adrian worked for is not been entirely down to him," he added.

"The design of cars was led by him. But it's not a solo effort. He needed the team of people around him.

"But it's inevitable that I expect it to make a difference. That's the logic behind the investment.

"Within a few months we should start to feel the influence, but of course next year will be the biggest step because it will be part of an integrally-designed package."
