Just to be 100% clear, the EPA range includes that buffer. There is no way around that.Other cars hit EPA range with ease.
Similarly, the Porsche is driven until it stops moving (I do not know what sort of buffer they have below 0% on the Porsche - but that buffer would also be included in EPA miles - which likely makes the Porsche results even more impressive - depending on the size of any buffer there).
Presumably Porsches aren't going to show capacity loss either for a while, since they'll take that out of the top buffer (probably? I assume people have data on this now). You can do a lot with a very large battery, but the Porsche efficiency is still pretty impressive (if it's the 350Wh/mi that I'm estimating, anyway - would be great to have some data - I guess I can back it out at 75mph from Bjorn's video...).
Looks like (168.6km*209Wh/km - 4.6km*290Wh/km)/(168.6km-4.6km) = 207Wh/km @ 120km/hr. (So 333Wh/mi at 74.5mph.). But this was not round trip and no idea what his elevation change was... So 350Wh/mi at 80mph is probably a bit low (15% higher aero drag so something like 10% higher overall drag, which would be about 365Wh/mi).
I'd basically ignore these calculations since we can't know the elevation change from the video...
