Formula 1 will introduce a two-step engine regulation change for the 2027 and 2028 seasons, significantly reducing the role of electrical power. This move aims to address issues with energy management and promote more flat-out qualifying laps. The current 53/47 split between the Internal Combustion Engine (ICE) and Energy Recovery System (ERS) will shift dramatically. For 2027, the balance moves to 58/42 in favor of the ICE, increasing to 60/40 by 2028.

This rebalancing is achieved by boosting the ICE’s maximum power from 400kW to 420kW in 2027, reaching 450kW in 2028, alongside a 5% and 13% increase in fuel flow, respectively. Max harvesting power will also climb, hitting 400kW by 2028. This gradual change is a compromise designed to ease the burden on manufacturers like Audi, who are new to engine development, while still moving towards a less electrically dominant powertrain. The FIA will expedite approval, with the World Motorsport Council needing to sign off on June 23. These changes promise a different strategic landscape for power unit development in the coming years.
