The emissions from the EV are largely because we’ve not yet gotten fossil fuels out of electric generation.
And what about a normal sized EV?
Even better of course. Not that there are many on the market in the US; automakers are increasing the size of every model.
Doubtful. Smaller cars are more aerodynamic and much higher fuel economy.
The same drop in energy needs applies to the EV too, along with sharply reduced emissions associated with manufacturing it.
