Summary

Story summary

FIA proposed raising ICE power to 450 kW (603 bhp) and cutting ERS output to 300 kW (402 bhp) for 2027.
The aim is to lower hybrid energy use, curb extreme harvesting, and shift balance toward combustion.
Mercedes-Petronas can meet the 50 kW boost because its ICE already exceeds 400 kW.
Ferrari may need a larger turbo to exploit the higher ICE power.
Audi and Honda must close sizable ICE gaps to remain competitive.
