For the 2026 F1 season, the cooling programs will powered by the otherwise organized electrical programs of the brand new automotive designs and can due to this fact be carried always.
However for the upcoming marketing campaign, because the system solely will probably be retro-fitted to automobiles when the 31C mark is reached, drivers have been given the choice of not utilizing it.
The added time earlier than it turns into necessary may even permit additional proof of idea research to be accomplished and for the programs to probably be additional tweaked forward of 2026.
