Aston Martin could be Red Bull’s ticket back to the front of the grid.
Autocar, a British weekly, reports that the British luxury road car manufacturer is in talks with the former world champions.
It follows Saturday’s news that, with Red Bull and Renault looking increasingly likely to split, Mercedes’ Toto Wolff is willing to "look at the new situation" if Red Bull is in need of a new engine supplier.
Wolff was responding to reports Renault is looking to buy the currently Mercedes-powered Lotus team.
"If Renault comes in and Lotus wants to get out of the contract," he told Speed Week, "we will find a solution."
Now, Autocar suggests that Aston Martin - which is 5 per cent owned by Mercedes - could take over the branding of Red Bull’s new engines.
An Aston Martin spokesman did not comment.
