Ford Performance Boss Backs FIA's 2027 Engine Overhaul
Ford Performance's Mark Rushbrook endorses the FIA's plan to shift F1's power unit balance from 50/50 to 60/40 ICE/electric from 2027, calling it a positive step for racing amid driver criticism of the current 2026 regs.
The FIA has confirmed plans to overhaul F1's power unit regulations for 2027, moving from the heavily electrified 50/50 split introduced this season to a 60/40 balance favoring the internal combustion engine. Ford Performance boss Mark Rushbrook has publicly backed the decision, calling it a good direction for the sport's future.
Why it matters:
The change addresses driver complaints about excessive battery management and reduced flat-out racing in the current 2026 cars. A more combustion-focused power unit could improve on-track action and simplify race strategies, potentially reshaping the competitive order as teams and manufacturers adjust.
The details:
- Technical shift: Fuel flow and ICE output will increase by approximately 50kW, while electrical deployment is cut by the same amount. The target is to bring power output closer to a traditional combustion-dominant formula.
- Driver feedback: Throughout the opening four races of 2026, drivers have criticized the current package for forcing unusual harvesting tactics and limiting flat-out running. The new split aims to restore a more natural racing rhythm.
- Chassis complications: Several teams had planned to carry over their 2026 chassis into 2027 under the cost cap. However, larger fuel tanks may be required, forcing redesigns. Potential solutions under discussion include cost cap concessions for new chassis development, shorter race distances, or different fuel flow settings between qualifying and races.
- Engine development concerns: The proposed changes have sparked debate about the Additional Design and Upgrade Opportunities (ADUO) system. Some manufacturers worry that allowing engine redesigns under current homologation rules could give certain teams an unfair advantage.
What's next:
Further discussions are needed before the 2027 package is finalized. One key variable is the timetable – whether the changes will be introduced mid-season or as a clean break for 2027. Meanwhile, Ford is pressing ahead with its Red Bull Powertrains partnership. Despite Red Bull's difficult start to 2026 (Max Verstappen has not finished higher than fifth in four races), Rushbrook expressed confidence in the long-term program.
"They are racers, they're committed to winning," he said. "We know it's going to take a lot of work, but we're fully committed with all our resources to help that program." The overhaul could also give Ford an early opportunity to close the gap to established frontrunners if the rules stabilize.
