Mark Webber will retire from Formula 1 at the end of the season, bringing to an end his 12 year career.
The Australian will take up a seat with Porsche as they aim to re-enter the Le Mans 24 Hour race in the LMP1 category, and will see Webber as their lead driver.
The 36-year-old has been part of the Red Bull team since 2007, scoring all nine of his career victories at the Tilbrook team.
Speaking about the move, he said: “I’m very much looking forward to this new challenge after my time in Formula 1.
“I can hardly wait to pilot one of the fastest sports cars in the world.”
Red Bull Racing team boss Christian Horner said: “I am sure Mark thought long and hard before making what has no doubt been a very difficult decision. His achievements in Formula 1 are extensive and I am sure he will continue to push hard and build on that record until the end of the season.
“We support Mark’s decision, he has been an excellent addition to the team since joining us in 2007 and we wish him all the best in the next stages of his career.”
Webber has been heavily linked with a move away from the sport since the team-orders row which exploded at the Malaysian Grand Prix.
Earlier this season, Webber celebrated his 200th Grand Prix start in Bahrain.
