Well, Ford, the new "Distance To Empty" algorithm doesn't work . . .

I got a 21 model in mid Dec of 21 and found the estimated range to be fairly accurate from the start, I live in New England and on a 100% charge range was about 190 miles in the winter and 270 in the summer. After the factory computer update in Dec now the estimated range is always 270 miles, I just barely make it to Vermont which is a 150 mile trip. It seems not only is the estimate stuck on the summer temps but my mileage seems to have dropped just a bit. I would love to have the update undone

Getting rid of the GOM would be, well, dumb. People need a rough idea of what sort of range they can expect, even if it is off by 40 or 50 miles. Having to know what your miles per kWh are at that moment, current SOC percentage, and then forced to do math, will be a much worse issue that won't drive adoption rates higher.

This is my first car ever with a GOM and I totally ignore it. I personally would prefer if the fuel level gauge were the size of the GOM and the GOM were some insignificant small font size instead of the way it is. A person who has driven a car for a reasonable period of time should get to know roughly what their fuel supply can support. I guess maybe people have gotten used to having GOMs in their cars and maybe don't really get to know their cars' range in the same way people can't remember important phone numbers because of phone books being in their phones. We're depending on a tool that doesn't perform the task. ?‍?

Went on a road trip in below freezing temperatures. GOM said 290 miles of range when I started with 100%, only got like 200

Thats about right on to what I get in Michigan, batteries don't like to be cold and the cabin heater is a battery killer as well as the steering wheel and seat heater. Warmer weather will soon allow longer distances even with the A/C on.

Just tell us how many kWh we have left and our current and average kwh/mile usage. Very easy math to tell how far you have left. Could even include range at current usage rate for those that are math challenged.

Couldn't agree more.

Math challenged or not, we probably shouldn't be driving trying to do math in our head or on a cheat sheet or whatever. There are already far too many distractions behind the wheel.

Thanks FordPass for letting me know. In FEBRUARY!! Too little too late.

Yep. Having the same issues. It's a fricking pain in the butt. For example today I'm doing about a 400 mile round trip. My first stop is 75 miles away. The car will show about 224 when I leave and will be around 110 when I get to the first stop. If I went by the GOM, I could just skip this stop and go to stop 2, which is about another 75 miles away. But I'd be lucky to make it to the second stop. I've now taken to just multiplying the GOM by 66 percent and that's fairly accurate. For example, that gives me a range of about 147 miles, which is almost spot on for this time of year. But what a pain.

It’s easy to figure out how a specific trip will go, car capacity x %charged x mi/kwh. What I like about these cars is how clearly we get to see the impacts of driving conditions on energy usage. For example, when I go to the mountains, I know the car will get much better mileage coming home than heading out. Keeping a blanket hedges heating the cabin if things get tight. Tiny sacrifices…

I believe that's exactly the calc it's supposed to use. It's a matter of what does your kwh/mile you want to do that math with. Last weeks downhill coasting to the grocery store? or yesterdays mad dash uphill to a soccer game. The GOM is doing exactly that Guessing. What it should do is present you with
Range:
Usually: 235
Highway: 200
Tailwind downhill: 320
It's supposed to avg. But it never has. In 10+ years of driving ev's they all guess based on some (n minus <number>) because dev's don't seem to think computers can do math I guess)

I'd rather have a live kwh/mile value displayed like Tesla's S. There's apps for that, we just can't use them (I think, unless a BT ODB2 works for that)

Except, the capacity of the battery changes a lot with temperature. On a warm day I have 91KWH capacity and on cold day I have 75 KWH capacity so I can't even do the math. 50% battery doesn't always mean 45 KWH.

 

[azerik]

It knows the capacity at it's current temp. So it's back to available KW times rounded value.

The Bolt EV/EUV has a display mode where it will show a High, Mid, and Low range figure, along with a trend indicator. Usually the High and Low figures were ~20% higher/lower than the mid range figure. The trend indicator was great to see if you were driving more or less conservatively, and could adjust as needed. I miss that. The Bolt also has a kW consumption/regen meter. Another thing I miss about the Bolt...

Honestly I don't think the majority of us want to whip out the calculator at the stop light to figure out if we'll actually make it to the next charger. I don't look at giving up peace of mind as a tiny sacrifice. They just need to go back to how they did it before.

Agreed. We all know it's only an estimate that will vary greatly by the type of driving (and other conditions). We just want it to be a reasonably close one for the type of driving where range matters most -- highway driving. Which seemed to be what it was tuned toward before.

I still like the idea of being able to select the driving assumption for the range meter in the settings:

Range Meter Basis
Recent Driving
City Driving
Highway Driving

It’s actually quite accurate for me now. The GOM was off by about 35% prior to this update, now it’s just about spot on the money.
