And we have lots of data about driving at 75mph from the US. In fair, temperate conditions, I get close to rated range at 75mph (with A/C off, windows up). Maybe a 10% hit (330 wh/mile).
I wonder if they had all the windows down and pano roof wide open? Those add a lot of drag, especially at high speeds.
even with windows down, pano wide open, music blasting, and heat or air conditioning on high it shouldn't make such a significant impact...possibly an extra 10-15% at most but not 50% like they are claiming...and I doubt they had the heat blasting (could be the biggest contributor to a decrease by 10-20%. In range in very very very cold weather and driving fast)

Hmm. We must have read different articles then. The one I read did a really good job showing some of the challenges that I experience with my Model S. And it should help avoid incorrect expectations about performance when got or cold.
Can you point out factual errors?
He he just did point out the factual errors, how did you not see that?
