ICE is dead, and none of the developments make it to road cars anyway. Meanwhile, battery/EV tech needs all the development it can get and F1’s have been frozen for years.
Make F1 road relevant again, not just aerospace on bubble gum tires. Let teams compete on the tech that actually matters to the motoring world.
Iirc Formula E has some kind of contract that guarantees it to be the only FIA sanctioned completely electric racing series until 2035, so some kind of ICE has to be retained in F1 until that point at least.
Edit: the agreement even goes till 2039
And Lewis Hamilton signed with Mercedes for 2025. There are always options that allow earlier changes.
