Williams Formula 1 driver and GPDA president Carlos Sainz says he hopes F1 management and governing body the FIA remain "tough" to push through power unit changes for 2027.
The sports' stakeholders are currently discussing significant regulation tweaks for next season to further improve the new-for-2026 rules. On the table is a move to a roughly 60-40 split between combustion power and electric energy, which could be achieved by raising the fuel flow of the V6 engine and reducing the energy deployment limits, while also increasing battery capacity to avoid cars running out of electric energy so often around a lap.
