Chief technical officer Adrian Newey has led the design of Red Bull's championship-winning cars
Newey, regarded as the greatest designer in the history of Formula 1, told Red Bull last week he wanted to leave in the wake of the controversy involving allegations about team principal Christian Horner.
The 65-year-old’s next team has not been decided but Ferrari are hot favourites to sign him.
Horner said Newey leaves Red Bull "a true legend" and credits him for "all of our greatest moments from the past 20 years".
"His exceptional ability to conceptualise beyond F1, his remarkable talent for embracing change and finding the most rewarding areas of the rules to focus on, and his relentless will to win have helped Red Bull become a greater force than even the late Dietrich Mateschitz might have imagined," Horner said.
Sources close to the situation have told BBC Sport there will be time for Newey to have a major impact on the gestation of a 2026 car design for whichever team he decides to join.
Italy’s Gazzetta dello Sport reported on Wednesday that Newey had met Ferrari team principal Frederic Vasseur in London to discuss a potential deal.
