The FIA has intervened in the rules regarding the so-called Boost Mode for the Miami Grand Prix. The extra power mode may not be used this weekend during wet conditions, for safety reasons. The drivers had already expressed their concerns to the FIA, which has now adjusted the rules.

For the Miami Grand Prix weekend, rain and possible thunderstorms are forecast, making the weather conditions look poor. The latter is especially significant: in case of lightning, the medical helicopter cannot take off, which means the race control can immediately stop or postpone a race. The FIA has adjusted the rules for this weekend: if it rains, drivers are not allowed to use the Boost Mode – which gives a car more electric power for a certain time – to gain extra power and overtake more easily.
Safety as the reason
In response to the concerns raised by the drivers about the use of Boost Mode, the FIA has made this decision. They want to prevent accidents that could otherwise occur. Therefore, the FIA now prohibits the boost button in wet conditions. The FIA has consulted with the FOM, team principals, and engine manufacturers and agreed to limit the maximum use of the Energy Recovery System (ERS), so drivers can better control the car with low grip. Besides the boost mode, the FIA has also tightened the rules around the Straight Line Mode. In designated low-grip zones, drivers are only allowed to partially adjust the aerodynamics to prevent sudden instability.

With the regulation changes already announced in April, teams are now allowed to increase the tire warmers for intermediates, but only based on driver feedback. This should improve grip and safety in changing conditions. The FIA was able to implement these changes due to the safety impact, without going through the full F1 commission process.
