> Do they weigh a lot more then a fully built ICE engine+transmission/clutch assembly+full gas tank? A 2018 Fiat 500e (electric, with a tiny battery bank good for only ~90 miles) weighs almost 3000 pounds, whereas the same car with ICE is ~2400lb. So yes, electric is a lot heavier. And that Fiat battery bank is mostly too small to be practical (had two of these on lease, gone now) so a a larger bank with usable range is even heavier.
