Heads to roll if RB3 bombs
That is the opinion of F1's oldest current racer David Coulthard, who finished the 2006 drivers' championship in thirteenth place. Red Bull placed seventh in its second season after buying Jaguar in 2004.
"We have to achieve more, otherwise people will have to be replaced," Scot Coulthard, 35, told reporters in Salzburg on Tuesday.
"If we don't take a significant step forward I would be extremely surprised."
The RB3, team designer Adrian Newey's first full effort, will be unveiled in Barcelona on Friday.
Albeit more than two years younger than the now retired Michael Schumacher, Coulthard fended off suggestions that he is nearing the end of his formula one road.
Coulthard debuted with Williams in 1994, after the death of Ayrton Senna. His 13 wins were all achieved at the wheel of a Newey car.
With his hair and stubble now spattered with grey, David insisted: "Age is an issue when it becomes physically more difficult to do certain things.
"Physically I know I'm in great shape."
