The day I charged to 100%, I was taking a ~140 mile trip and figured I’d try charging to 100% like all the cool kids do. It was a mild day, but started raining on the return trip. I don’t recall the exact numbers, but I averaged something like 260wh/mi over the trip with heat on the way back driving 80mph. The way there I was getting very low 200’s while drafting semis and the energy graph was showing some absurd range that was likely achievable. I don’t think there’s anything wrong with the car, and I don’t believe the cars indicated range is terribly accurate. Up until that point the battery was never above 80% and I never discharged it below the mid 50’s, so maybe it just has no clue and starts ticking off miles.
