Why an Aston Martin-Red Bull engine deal is not on the cards

Aston Martin has reiterated its commitment to Honda, while Red Bull Powertrains says it is not prepared to supply an outside team. That was the message from both sides after the United States Grand Prix, where questions about a possible engine partnership drew attention in the paddock despite no indication that talks were under way.

The speculation grew from a BBC Q&A discussing whether teams might want Red Bull’s power unit. The article said no team was currently seeking a new supplier, while noting that Aston Martin had been surprised by Honda’s early deficit. Aston Martin considered its options but chose to stay with Honda; the possibility of a rethink was raised only if the manufacturer failed to make expected progress in 2027 or 2028.

Aston Martin says the Honda works partnership remains its plan

Aston Martin trackside chief Mike Krack stressed that the team had a long-term relationship with Honda and expected to share in the success if they could win together. The manufacturer had reached its 500th race over the Austin weekend.

A switch away from Honda would mean abandoning a works arrangement that Aston Martin selected as part of its development. The source of the appeal is closer integration between the power unit and chassis, as well as the opportunity for the team and manufacturer to work together. Adrian Newey said Honda had projects under way and that he saw promise in them, despite the current shortcomings.

Newey also contrasted Honda’s approach with the difficulties Red Bull had faced with Renault, saying the problem was particularly bleak when a supplier did not appear willing to address its performance. Honda, he said, was putting significant effort into improving its position. Aston Martin’s interest in that partnership remains clear, making a move elsewhere an extreme step at this stage. The team’s wider activity has also included its Austin partnership livery.

Red Bull says supplying another team is not a near-term option

Red Bull team principal Laurent Mekies said the power unit’s performance had attracted interest, but the company was not in serious discussions to supply another team. He added that its focus was on improving the engine and its integration into the car before considering an additional customer. Nothing is expected to change over the next year or so, although Mekies did not rule out a different position further ahead.

Red Bull already supplies its own team and sister squad Racing Bulls, giving its power-unit project four cars from which to gather data. That reduces the immediate incentive to add another customer. The engine has also attracted attention following the FIA’s ADUO ranking; the related review of the ADUO findings provides further context.

For now, the comments point to two separate realities: Aston Martin is backing Honda, and Red Bull is concentrating on its own programme. A partnership between them is not an obvious prospect at present.
