There is a standard for range - WLTP - does the US subscribe to it? The W stands for Worldwide.
My car has a WLTP range of 323 miles. I've managed better than that. The standard itself is pretty decent and far better than the old one.
EVs are different to ICEs. Mind you they are both pretty efficient at around 50mph - funny that. EVs hate cold but if you pre-heat the battery, then its not so bad. An ICE can always have a bigger tank and you can easily pop a 15l can in the boot (trunk) to grab an extra 50 miles or so. EVs don't have that flexibility.
However, I pay 7p per KWh to charge my car and I fuel up at home instead of at Tesco. My "tank" costs about £5 and I can get about 300 miles out of it.
My other car (Renault Clio) costs about £70 at the moment (it has been far worse) to fuel up and I'll get roughly 700 miles out of it.
In Europe I think that EV vs !EV is almost certainly won but I do get that in the Americas, where it can get proper chilly at times and the distances involved can be huge means that an EV might not be indicated without a lot of caveats. EVs mostly do cost more too for the initial purchase, which isn't helpful.
Despite all that, do note I routinely pay roughly £5 for 300 miles, and I don't have to piss around with garages. My car plugs into my house!
