Red Bull Racing's David Coulthard will bring his 14-year Formula One driving career to a close at the end of the season.

The 37-year-old Scot, who won 13 races, made the announcement on the eve of the team's first practice sessions ahead of Sunday's British Grand at Silverstone, which will be his 237th Grand Prix.

Coulthard drove for Williams and McLaren, but will carry on after his retirement as a consultant for Red Bull.

"My decision was taken earlier this year and is based on a desire to stop while I am still competitive," he said.

"I'm still enjoying the immense challenge that Grand Prix driving represents. I also have the desire to look for new challenges within the sport.

"I will remain actively involved in the sport as a consultant to Red Bull, focusing on testing and development of the cars.

"I have an open mind if I will compete again in the future, in some other form of motorsport, so I am definitely not hanging up my helmet.

Coulthard, who won the British Grand Prix in 1999 and 2000, began his F1 career in 1994, when he was promoted from his role as test driver at Williams following the death of Ayrton Senna.

Since then he went on to take 62 podium finishes, the most recent of which was in Canada last month when he finished third.

He has also scored 533 Formula 1 poins up to and including the French Grand Prix two weeks ago, making him the most successful British driver in the history of the sport.
