I do hate that they lie about the range in their advertising and from their salespeople, and wish they would stop doing that....Anyway, my 2016 SR is my primary vehicle and I love it, but making false claims does nobody any good.
Years and years ago, in the fledgling days of computers, 1kB meant 1024 (which is a very convenient power of two), and 1MB meant 1024 * 1024, or 1,048,576 bytes. You'd buy a 20MB hard drive (I know, it seems ridiculous now, doesn't it?) and it would actually be able to contain 20,971,520 bytes of data.
But then some bright marketing boi pointed out that his company's "80 megabyte" hard drive could actually hold 83.886 million bytes, and the metric prefix "mega" actually means a million, not 1024^2, so referring to it as an "83.8 megabyte" drive would be nonstandard, but not actually untrue, and would make that company's drives look a little better than the competition's. Of course, that was only true for about a week, until the other companies adopted the "new standard" and everybody's drives looked the same again.
Similarly, when solar panels first came out, they were rated by their actual output capability, but another bright marketing boi noticed that the ratings weren't regulated, so if he took the very highest voltage the panel can put out (no-load or "open-circuit" voltage) and multiplied it by the current the panel produces into a short circuit, he'd get a higher number that makes his product look better than the competition's -- never mind the fact that the panel has no shot in hell of ever actually producing that voltage and current at the same time. Again, it made his product look better for about a week, now everybody's panels are rated the same...if you don't rate your panels that way, your product looks inferior just because your marketing team is honest.
EVs are the same way. For my 2014 SR, they took the very highest open-circuit voltage the battery pack puts out, 114V, and multiplied it by its nominal Ah capacity, 100 Ah, to give it its 11.4 kWh rating. But we all know the battery voltage drops considerably the instant you apply any load, drops even more as the battery discharges, and some of the capacity is reserved by the manufacturer to avoid damaging the battery by discharging it very low. The upshot is the usable capacity is realistically more like 10 kWh, but again, if you rate it realistically, your EV will look inferior to another company's, even though they're exactly the same. One marketing person tried to game the system and now everybody has to lie.
It's easy to get on any manufacturer for exaggerating their range performance, because they all do it. They all do it because they HAVE to do it. If they don't lie like everyone else does, people will think their product is inferior, even if it as good or better than the others.
