Mileage understanding

[HOTAS]

This subject has been a huge frustration for EV and hybrid Mfr’s for decades. The 2004 Toyota Prius was originally rated as a 60mpg car. That was true at 60mph or less and driven delicately.
But the average consumer didn’t drive like that, and complained like hell that Toyota was misleading. They later changed it to like 48mpg.
Sad, because I could consistently get 60mpg.

(If exploited with extreme driving techniques, hypermiling with outrageous speed fluctuations , it could get 100mpg. Yes 100mpg !)

It’s been the same struggle with consumers, conditioned by gas cars, ever since.
Bottom line, EV drivetrains are extremely efficient, but extremely affected by the “varaiables”…., which are many.

There was a time .... late 2022 or early 2023, IIRC when Ford adjusted the algorithm to show us the ideal range once the SOC was above 80%, many of us protested that was misleading when we could clearly see the projection was highly optimistic for extreme seasonal conditions.

Then came the onslaught of whiners complaining of the GOM dropping like a rock after the first 10 miles of driving, see Hoovies Garage video as an explainer....

Ford revised the calculus adding back a measure of pragmatism, I'd rather be told the reality of a situation then have smoke & mirrors.

The 300 or 320 mile range is for comparison of vehicles, giving us an insight as to the differences in ability and efficiency of one vehicle over another, how it performs in my hands with my leadfoot is another story.

December 2022...Just tell me how my vehicle is going to perform. You know it, I know it, lying to me is not going to change it. If it's 0F I am not going 300+ miles on a charge.

When you drive an ice vehicle, do fill up the tank based on your fuel gauge or what the "miles to empty" indicator says? How many Ice drivers even ever use their "miles to empty" screen?

I did this with the last three ICE vehicles I owned, but I realize I'm more of an exception rather than the norm. Even though the GOM is an educated guess, for me the numbers it provides is more real-world appropriate than a percentage, especially the VERY rough percentage that ICE vehicles provide...

Remember, the traditional gas guage we all looked at for years, was also a % meter.

A very rough percent meter, with a resolution of 12.5% (if you had eighth tank graduations) or perhaps only 25% (quarter tank marks that some cars have). You never REALLY knew what the actual percentage was in the tank, but nobody ever complained. Not to mention that completely filling the tank would usually put the needle above "F" and give you about 30+ miles of driving to get it down to "full".

Now that we have actual percentage readings, everyone holds it as the holy grail. Sort of like a couple who were perfectly comfortable in their home with an analog thermostat that start to lget into arguments over the setting once a digital one is installed. One is freezing at 70 while the other is sweating bullets at 72. (Shout out to Corner Gas fans!)

I never think of my distance from home (or wherever charging is to take place) as an SOW percentage, but I do know if I'm 10 miles from home, I better have a GOM saying I have a few extra to feel comfortable about making it.

My FFE has a feature that has it display "surplus" range when you enter a destination on the nav system as a charge point. It's just the GOM range minus the distance to the charging location, but it's really helpful. Start a trip with a surplus about 10% above the actual distance, and you'll rarely have range anxiety, even with the FFE's 100 mile range in mild weather.
