Talk about confusing.  Check out all of these different ways various government agencies use to estimate EV battery ranges.  I wonder which one the EV manufacturers use when advertising their maximum driving range?  If I recall correctly, they don't exactly specify which one they are using in their range claims. At least Zero seems to be more up front with their range claims than just providing only one number as most EV manufacturers seem to do in their advertising:   https://greentransportation.info/ev-charging/range-confidence/chap5-ev-range/epa-estimates.html

I believe Zero uses the dynometer methods to get their numbers.

Some smaller EV manufactures don't use these methods but rather goes out and gets "real world" numbers to make their claims on. (At least the other EV manufactures I have talked to do this from what I can tell.) Some will even tell you which roads / route they use at given speeds to get the numbers if you ask.

To me I am more interested in said real world data than some dynometer data ...

The nice thing about dyno data (for the manufacturer) is that there is no wind resistance.
