Aston Martin is poised to become Red Bull's title sponsor for the 2018 season, according to 'well-placed sources' at Motorsport.com.
Red Bull team boss Christian Horner hinted on Friday that Red Bull would be strengthening their relationship with Aston Martin, with many speculating that they would become their eventual engine supplier.
But, for now at least, Aston Martin look set to become a more visible partner of Red Bull's by being their main title sponsor next year.
Horner, though, would not entertain the latest rumours.
"You can speculate all you like but I'm not going to confirm anything," Horner told Motorsport.com.
"We've got a great relationship with Aston, obviously working on and developing the Valkyrie hypercar for them.
"They're doing a great job, the product is great, and they've got a lot of great stuff in the pipeline. There will be news to follow in weeks to come."
