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.
