Coulthard – no regrets as F1 career nears end
The 37-year-old Scot announced on the eve of the Silverstone event that, after 15 consecutive seasons, he is to retire as a grand prix driver at the end of 2008.
After Brazil in November, he will have contested nearly 250 races, winning 13 times first for Williams and then McLaren.
"I've had a long career and many good opportunities, said Coulthard, who now drives for Red Bull.
In 1998 and 1999, Coulthard's McLaren teammate was Mika Hakkinen, who won both those drivers' crowns.
"I'll come out of this (year) knowing I had world championship-winning cars. I'm not going to think, 'Damn, I never had that chance'," he told the Daily Telegraph.
"I did get that chance, but I never quite delivered the ultimate result."
