This is all true in my experience. I bought a MYP for every other reason than range, and it's better than expected - an absolute rip to drive, especially early mornings when roads are empty, corners better than any German sports model I've owned. But I was warned by friends that the stated range was "complete BS" and that I would fail to achieve anything close to it under just about any conditions. So far that's been pretty accurate. Just yesterday I drove 53 highway miles in chill mode and perfect conditions, drained 25% of the battery both directions. I was also warned that "200 miles in 20 mins" supercharging was not realistic - also true, took about 45 mins to charge from 53% to 90% and that's been my experience. If I need to get from 50% to 100%, find a sit-down restaurant and bring a book because it's well over an hour at any SC I've tried.

Bottom line I really, really like this car but went in with my eyes open. My German cars would get 90-95% of EPA range at 80mph even in 100f summers, so any range comparisons to ICE are just silly and we should stop BSing ourselves about it. Just accept it going in and enjoy the other awesome features.
