I know some here have seen consistent numbers for rated range throughout ownership of their Model 3s (Models 3?). Others, myself included, have not. I've been everywhere from 287 to 311 (never did see that promised 325) in my LR RWD.
I am aware that these numbers mean essentially nothing. When my range dropped the first time, I contacted Tesla and had them look into my battery health, only to be told that everything was fine and that the reported number was based on charging patterns, quirks of the BMS, and random other variables. I stopped worrying about it, and it's gone back up and down a few times since. Aside from Tesla's assertion, my daily commute to work is a pretty good indicator that everything is fine. I lost 7-8% capacity each way when I took delivery of the car, and I lose 7-8% each way now, 36K miles later. This is true at pretty much any reasonable SOC.
So having said all that, what's the point of that range number? Is it just a historical leftover from ICE vehicles? Does it serve any purpose other than to freak out new owners about their "range loss"?
Incidentally, my car is set to display percentage not range. I'm only even aware of any of the above because I use TeslaFi.
