In a significant shift for Formula 1, the power unit regulations will change from a 55/45 split between internal combustion engine (ICE) and electric power to a more combustion-focused 60/40 in 2027. This decision follows feedback from drivers who experienced performance issues in 2026 due to excessive energy harvesting requirements. The new regulations aim to enhance vehicle speed, safety, and driver intuitiveness while addressing concerns such as energy starvation on the track. The shift in power distribution will improve competition by allowing for more consistent driving behavior.

By the Numbers
  • ICE output will increase by approximately 50 kW (roughly 67 bhp).
  • ERS deployment power will decrease from 350 kW to 300 kW, shifting the power split to nearly 60/40.
Yes, But

While the 5% shift toward ICE is acknowledged as beneficial, some experts argue that a larger transition to a 65/35 split would have been more effective for performance enhancements. The adequacy of the modifications remains debated among stakeholders.

State of Play
  • The FIA and teams are collaborating on hardware modifications, such as larger fuel tanks.
  • Immediate tweaks from earlier in the season have already been positively received, indicating successful early responses to performance concerns.
What's Next

Further technical working groups will finalize details before manufacturers vote on the changes, followed by F1 Commission approval. The implementation of better race procedures and visual aids is also anticipated to roll out soon, enhancing overall competition in the upcoming seasons.

Bottom Line

The adjustments set for 2027 signal Formula 1's commitment to blending improved racing dynamics with sustainability objectives. With enhanced driver control and performance, fans can look forward to a revitalized and more thrilling racing experience.
