Do we now have 3 terms regarding miles, ideal, rated, and projected?
In Cinergi's video at 205V*40A=8kW he showed us 16 projected mph and 20 rated mph, but even if we scaled that up to 9.6kW on a 240V that would only mean about 24mph, not 31 as stated in the Tesla marketing.
I think the 31 relates to 300 ideal miles, and then rated miles refers to the EPA's 265, and projected refers to how you're really driving and whatever range that implies.
From what I can tell in the various videos the car doesn't reference 300 ideal miles anymore, which I think is good. Stick with the officially rated figure.
