Why Red Bull Is Reluctant to Share Engines with Aston Martin
Red Bull's refusal to supply engines to Aston Martin isn't about readiness, but rather concerns over potential financial losses. The team is wary of losing prize money if Aston Martin outperforms them with their engines.
In the world of F1, engine supply can be as much about strategy as it is about engineering. Red Bull's recent decision not to sell their power units to Aston Martin—or indeed, any rival team—underscores this point. While Red Bull's team principal Laurent Mekies publicly claims the decision is due to their engines not being 'ready,' there's a more pragmatic financial reason lurking beneath the surface.
Aston Martin has shown interest in Red Bull's engines following a somewhat rocky start with their current partner, Honda. Despite their early struggles with vibrations and a clear power deficit, Aston Martin is soldiering on with Honda, who reversed their decision to exit F1 after the 2025 season. The new 2026 regulations were designed to attract the likes of Audi and to convince Honda to stick around, even leading Honda to sign a factory partnership with Aston Martin. However, these efforts haven't yet borne fruit, with Aston Martin sitting uncomfortably low in the standings.
The intrigue around Red Bull Powertrains stems from the unexpected success they've had with their internal combustion engine (ICE), named the best by the FIA on more than one occasion. Red Bull, against initial skepticism, has thrived, with Max Verstappen taking wins in Bahrain and Singapore from pole positions. This success has naturally piqued the interest of other teams, including Aston Martin, who are eager to improve their standing.
Yet, it's not the technical readiness that's keeping Red Bull from sharing their engines. As Mekies pointed out, "We don’t feel we are ready for that." But the real concern, as reported by OE24, is financial. Red Bull fears that supplying engines to a team like Aston Martin could upset the balance in the standings, potentially causing Red Bull to lose out on significant prize money. The FIA’s €15 million price cap on engines doesn't compensate for the potential prize money loss if Aston Martin, with their technical prowess under Adrian Newey, were to outscore Red Bull or their junior team, Racing Bulls.
Currently, Red Bull stands third in the constructors' standings, a position that could bring in around $140-150 million in prize money. Racing Bulls also hold a lucrative fifth place. Aston Martin, on the other hand, is languishing in tenth, only above the new entrant Cadillac. If Red Bull were to supply Aston Martin with engines that eliminate their current limitations, the Silverstone team could rise in the ranks, threatening Red Bull's financial take from the sport.
Thus, while Mekies diplomatically cites engine readiness as the reason for not expanding their customer base, the underlying issue is one of financial strategy. Until Red Bull can ensure that supplying engines won't jeopardize their or Racing Bulls' standings—and consequently, their prize money—they're likely to keep their engines in-house.
