The estimated range on the window sticker is legally required to be the range derived using EPA's well-defined testing regime, regardless of how realistic (or unrealistic) that testing regime might be. The requirements are the same for all makes and models, making it useful as a comparison between cars more so than a true estimate of what any individual driver will achieve. My ICE Honda Pilot never, in 140K miles, achieved it's EPA estimated gas mileage with me driving. My wife, on the other hand, routinely exceeds EPA estimated mileage. She drives a lot slower and less aggressively than I do.My Leafs didn’t report ~10% range shortfalls like the Ariya does, or require e-Pedal to report full range at 100%. The Ariya’s being driven/charged in a climate with 60-degree daily temperatures, no significant load, etc. My experience is markedly less than what was marketed, even without being used in snow or lots of other weight.
Based on the independent testing spreadsheet shared earlier in this forum, it looks like Nissan may have some history of overstating range by 11%? In any case, advertising a car’s range based on what a bone-thin driver might get with hypermile techniques and no load strikes me as ridiculous.
Here's some information on that testing for EVs:
