Red Bull Formula 1 team principal Christian Horner says the team does not have a replacement lined up for outgoing title sponsor Aston Martin.

Following Racing Point owner Lawrence Stroll takeover of Aston Martin, the luxury British sportscar manufacturer will be focusing its efforts on its newly rebranded F1 team from 2021 onwards, leaving Red Bull without a title sponsor.

Aston Martin’s logos have featured prominently on Red Bull’s cars since the title sponsorship deal begun back in 2018, but the agreement will end at the end of the year.

Horner confirmed that Red Bull has no plans to find a new title sponsor.

"We don't have a title sponsor replacing Aston Martin for next year," he said.

"We will have new sponsors that we introduce into next year. Aston Martin obviously won't be on our car.

"We've enjoyed four years, three years as title and four years with them on the car. We've helped to push the brand, and we've obviously enjoyed a great relationship with Valkyrie.

"Obviously our deals were constructed under the former CEO Andy Palmer, who was always been tremendously supportive of the team.

"And with Lawrence buying the business, it obviously was natural for them to exit. We'll look forward to seeing the Aston Martin name live on in F1 next year.”

Part of the tie up with Aston Martin resulted in a technical collaboration on the Valkyrie hypercar project, which Horner stressed will continue as planned despite Aston Martin and Red Bull parting ways.

"The car is running, and we are doing all the testing,” he explained. “Of course the relationship goes until all the cars are completed through Red Bull Advanced Technologies."
