The real game-changer, for EV's, is supposed to come on-stream next year when Toyota start producing their solid-state batteries. No electrolyte, so much less cooling effort required (smaller heat-sinks) - half of the weight, of current battery packs, is the cooling required (it's the electrolyte which catches fire). Their greater efficiency, and lighter weight, should mean 800+ miles on one charge, and full charge being achieved in just a few minutes. We shall see...
Pity the Denali EV didn't live up to the advanced billing - GM were originally promising 1000hp 'as a statement'...
