I don't agree that it looks impossible for EVs to work in rallying. Baumschlager ran rallies in EV Fabia with zero changes to their schedule.

So it can work just fine with minimal itenary changes. Fast charging truck after 1-2 stages that charges only for short period for 5-10 min per car should be possible for the 10 top cars running.

The only real issue is the need for sound due to safety and spectating (throttle input). Solution is to set a rule dictating the sound levels in various situation and introduce a common sound system.
