As long as you don't need to run the A/C all the time and not at ECO, and don't need to cool the battery at the same time, and not drive in the mountains, you can get the range you mention.Interesting report. Haven't been able to run a test at your high temps as we don't get temps that high here. Thank goodness. Don't know how people can live there. And your speeds are higher than speed limits I am allowed. From your results it appears that high temps hit range as much as low temps and maybe with a little faster falloff. Remain convinced that maximum range at highway speeds occurs around 68F where you can get a little more than 300 miles.
It is a desert here...means it does get hot AND there aren't a lot of human habitations along our Interstates that pass through our deserts. Not a lot of places to put charging stations, plus since the chargers (and their associated transformers) sit out in the blazing sun on asphalt parking lots/pads that get up to 160F, as an engineer, I can see that their reliability suffers. There are times when my iPhone and iPad tell me they are too hot to work when I have left them lie on my car dash here.
I have been told that Teslas run the cabin A/C to keep the cabin temperature from getting above 105F to make sure their large touch screen display work. Means that when you park here or Las Vegas uncovered you can run down your battery just keeping the cabin at 105F when it is 115F! A friend of mine just told me her Prius got up to over 120F yesterday when she shopped at a Costco in Henderson (Las Vegas).
