Williams driver Carlos Sainz has urged Formula 1’s governing body to take a forceful stance in implementing proposed changes to the 2027 power unit regulations, even if it means leaving teams “with no choice” but to comply. The FIA is currently negotiating with teams and power unit manufacturers over modifications to the engine formula that would shift the power split from the current 50:50 ratio between internal combustion engine and battery system to a 60:40 configuration.
The proposed adjustment aims to reduce reliance on the hybrid battery system while increasing the contribution from the traditional combustion engine. However, the change faces significant resistance from two of the five power unit manufacturers – Audi and Ferrari – while Honda, Mercedes HPP, and Red Bull Powertrains are believed to support or have confirmed their approval of the modification.
Under F1’s governance structure, any changes to power unit regulations require a supermajority vote from the Power Unit Advisory Committee, meaning four of the five manufacturers plus approval from the FIA and Formula 1 Management. The current opposition from Audi and Ferrari would block any such vote, creating a deadlock in the decision-making process.
Speaking to media including RacingNews365, Sainz emphasized his belief that F1’s regulatory bodies should push through changes they deem beneficial for the sport, regardless of manufacturer resistance. “If they say it should be like that, I’m pretty sure that teams who are complaining or maybe not fully aligned with them will have no choice other than to do it,” the Mercedes-powered driver stated. “If it is for the good of the sport, for the good of the racing and the show, I’m a big fan of the rulers taking a very strong approach and a strong stance.”
The Williams driver expressed optimism about the potential improvements the proposed changes could bring to Formula 1’s spectacle, while acknowledging that the current 2024 regulations cannot be significantly altered. “I think there is scope and a margin to improve this engine and these regulations with what is being proposed for next year,” Sainz added, indicating his hope that the deadlock can be resolved before the 2027 season begins.
