If GM wants to do this right…
If GM wants to do this right, build a V8 only model, build two EV models, and it would most likely sell. The idea of a EV only model will do nothing but completely kill the brand as a whole because it won't be really affordable in the way the gas powered cars are. Remember, EVs require chargers, and those are not cheap (think 20-30k at your home) or living a life of always having to go sit somewhere else to charge your car for 30-45-60 min at a time...
