The edmunds article is probably the best source, but this is the article that I saw yesterday with some of the numbers. Some are quite noticeable in their drops like the 2018 S Performance went from 310 mi to 256 mi. All the non-Teslas got higher than their EPA rating. With the Porsche Taycan 203 mi to 323 mi.

That's an article too early. (Though they seem to address later objections in their edit.) It turns out that Teslas display more of their capacity under "zero range," giving more of a warning/buffer to drivers at low battery. The Teslas turned out to drive farther than the other cars when displaying "zero range."

The "zero range" tends to be a safety buffer for gas engines and electric motors alike and should not be included in the official range statements, imo.

The way I use my Model 3, I intend to almost never go below 20% and almost never go above 80%. I'm just fine with including the buffer in the stated range. Given how batteries actually work, I can understand Tesla's approach to the buffer, and in the long run, that's what's actually better for vehicle longevity, fleet-wide.
