No, set off at 80% which showed 400 km range on the GOM. I have left my Aeros on, I don’t like the look of the wheels without them. My lifetime efficiency is 166 Wh/km but I’ve only driven 388 km so far. Since the last charge it is 147 Wh/km. That is very good. My LEAF’s lifetime efficiency is 142 Wh/km, and it is a smaller and far lighter car.
Your comment about driving with the heater on is a key bit of info. The heater in Model 3 is resistive, not reverse-cycle AC, so uses a LOT more power which would have a noticeable effect on range and reported efficiency.
Yes, much better to use seat heaters than the main heater!
