I think it is safe to say, as far as mileage (MPG) is concerned, all most all the people wanting an Elio for the mileage is mostly do to it's relationship to overall cost savings, not range. Therefore an EV for most Elioer's is totally out of the question regardless of it's MPG.JMOAn EV will ALWAYS win in fuel savings so long as you can drive within it's limited usable ability(dependant on battery size vs charge time vs available chargers). The only EV I've driven that truly beats an elio fuel wise is a Tesla model s but they aren't in the same sport much less the same ballpark. The 2013 Nissan leaf with quick charging is a distant second to the tesla, and other manufacturer's EV options just aren't there yet.
I looked at taking our loaner leaf on a road trip and was quickly turned off by charging availability outside the major markets. Taking the trace to Tupelo, MS has been a fun weekend jaunt in most of my cars. In the leaf it's a strategic endeavor to see if you can even make it there and back without begging to borrow a 120v outlet!
Here's the charger availability in Nashville, TN

So will I buy an EV, sure if I want a car to drive around Nashville for cheap, but the Elio gives me range as well as affordability.
