F1 Stakeholders Reach Agreement on 2027-2028 Power Unit Refinements

The FIA, Formula One Management, and power unit manufacturers have reached a consensus on a series of technical and financial amendments to the current engine formula. The agreement aims to fine-tune the next-generation power units by easing the intense energy management demands that have become a primary concern for drivers and teams since the new regulations took effect.

Why it matters:

The 2026 regulations introduced a significant shift in energy distribution, but real-world application has highlighted operational challenges. By gradually increasing the reliance on internal combustion, F1 is prioritizing "driveability" and reducing the tactical burden of battery management, ensuring that on-track performance is determined by driver skill rather than energy conservation.

The details:

• 2027 Transition: Fuel flow will increase by 5%, raising ICE output from 400kW to 420kW. Simultaneously, maximum electric motor power will be reduced to 300kW, though the Overtake Mode will remain at 350kW to preserve attacking capabilities. Energy harvesting limits will rise significantly from 250kW to 375kW.
• 2028 Evolution: A further 13% increase in fuel flow will push ICE output to 450kW, aiming for a long-term 60/40 power split. Energy harvesting capacity will further increase to 400kW.
• Financial Flexibility: To support these transitions, adjusted financial regulations will be implemented, providing manufacturers with additional cost-cap flexibility to integrate the hardware and software updates.

The big picture:

This approach represents a strategic move toward evolution rather than revolution. By opting for a phased rollout, the sport avoids a disruptive mid-cycle overhaul while addressing critical issues such as the large speed differentials between cars and the excessive "lift-and-coast" behaviors required by the current energy limits. It balances the performance goals of OEMs with the financial realities of the cost cap.

What's next:

The proposed amendments are scheduled for final ratification by the FIA World Motor Sport Council during their meeting in Macau on June 23. Once approved, these changes will set the roadmap for the latter half of the current hybrid era, shaping the competitive landscape through 2028.
