On the original topic: Yesterday on my way from Toronto to Kingston, I was doing 120km/h and my consumption average was 195kwh. The A/C was ON between 20 - 21°C (range mode was OFF). The weather was cloudy and the temperature was around 21°C. I was heading east and the wind was south at 6km/h.
I noticed that the consumption is at its best when the temperature is between 16 - 21°C (not raining, obviously)
I started with a 95% battery and had around 11% (I hope I'm not wrong on this) when I arrived.
