I wasn't aware those are getting 8 - 10mpg in city, wow. Ya, I'm glad they're replacing those soon.

This link referenced a study where hybrids take the equivalent of 325 gallons to produce[0]. This one is 474 for ICE[1] Let's say an EV is 500 - 1,000 gallons of gasoline energy then.

One year of those Grumman LLV on the road, 1,500 gallons at 12k miles/yr is easily out-polluting the entire production and use of an EV replacement.
