Also, has your range actually dropped OR has the display just been showing lower range. Have you been monitoring your efficiency?
I have always tried to calculate my miles per kWh. And I always come up with 2.3+. Perhaps that has changed in the last week or so when the temperatures have finally dropped into the 40s and 50s. But the general inconsistency was happening with very moderate temperatures as well.

The one thing I haven't done is charged it to 100% and driven it way down and see how far I can drive and that is only because I don't yet have a way to do a full charge overnight. Hopefully I will have that soon.

However, 270 was not my driving. As I said when I track my state-of-charge drop and mileage I always calculate around 2.3+ miles per kWh. That should be over 300 miles of range. The trip meter I have had going since I have owned the truck also says 2.3 miles per kWh.

Another complication is that Ithaca has a lot of hills.

I understand everything you are saying and all the complications. But the numbers have never added up. I hope it is just really bad ad guessing range and that there is not something else going on.
270 was your driving. It was the GOM predicting range based upon your driving.

Your method of determining range is the most accurate. On a trip, I look at my % of battery left. I then multiply it by my battery size (91 in my case), then by my current miles per kilowatt hour on that trip (This Trip). That's my max range.

Yes, I know the hills well. Way above Cayuga's waters, there's an awful smell. Some say it's Cayuga's waters, others say Cornell.

I spent much time at The Haunt and The Nine's, among others.

L1 (120v) charging does not affect the GOM, it does not matter where or how the power comes in.

Your GOM range is a future estimate based on past driving style, weather, temps, etc...

Nothing wrong at all with your vehicle - very common when colder temps start.

Just drive more conservatively, less cabin heating, use seat heaters & steering wheel heater.

BTW if you do get L2 (240v) charging, you can pre-condition your truck ahead of time so that the batteries are warmed up and the cabin temps are warmed without impact on your battery as it powers from the house/garage.

#Metroshot I did the "pre conditioning" the other day and it was great. I plug into a "shared" charger in my parking garage at home. The car charged overnight. Then then

I agree. My numbers just do not add up.

I am also having weird range GOM problems. I have an extended range Lariat. When I picked the truck up in August it had a range of about 316 miles. But since then the predicted range when fully charge has been dropping. It was around 270 miles for a while but it has been dropping a lot. This morning it is predicted to have a range of 235 miles when fully charged!

However, when I keep track and do my own calculations I almost always get around 2.3+ miles per kWh.

I realized the temperatures are dropping here in central NY, but this has been happening even when the weather was still quite warm.

I would like to actually test out the full range, but unfortunately I don't yet have a proper charger at my house so I try not to run the truck all the way down. I wonder if constant trickle charging confuses the GOM.

I’ve also noticed that the 100% range estimate goes up the closer you get to 100%. I’ve seen it say 270 when i plugged in then when i got closer to 100% it estimated 290. This is a consistent issue that i’ve noticed under all conditions.

It's amazing how this simple concept confuses so many.

Your Trip odometers reflect the actual efficiency you have had since the last reset.

The Guess-O-Meter uses your recent history (no documentation as to how many miles it looks back) and predicts your range based on current conditions. It does not multiply your lifetime miles per kilowatt times your battery size. It is always conservative. It reacts to temperature.

Ford is working on "intelligent range". This will take more factors into account, and will change based on a trip you put into the navigation. So, in the near future, if your range is say 250 miles, and you put in a trip that involves going way up into the mountains in colder weather, you might see the range immediately drop to 200 miles as it reflects the current navigation trip. Cancel that trip from the navigation and it may jump quickly back up to 250 miles. Again, this is being tested, is not yet rolled out.

My lifetime on my Mach-E is around 3.1 (haven't looked recently). 3.1 x 91 = 282. I have NEVER seen 282. I usually see around 250 in warm weather, and 180 in cold weather.

On an ICE F-150, the range shown takes your history times the gallons in the truck. It does NOT look at any current conditions, only history. Where's the outrage that the range shows 200 miles, but then when you drive up into the mountains in the cold you only got 150 miles before running out of gas?

if you have never owned an EV the mileage thing is weird. A gas engine does vary based on speed, weather conditions, terrain and other driving habits, but that variation is much smaller and hardly noticeable. Also when driving a gas vehicle, I think most of us never equated certain fuel levels to an actual range. You would just get in the car and say ok I have a 1/2 tank, 3/4 tank or whatever. Now we have an EV and those same variables have a larger impact on range. Our brains are more mileage focused. It is definitely a learning experience. It appears from seeing all the posts that the quoted max range either done by the EPA or Ford does seem on the optimistic side. From what I'm reading is that most are only seeing the quoted range in the most ideal situations. My other EV has a 256 mile range and it easily averaged at that range. For non-winter 8 months of the year I would routinely see over that most of the time. My driving is probably 50/50 Hwy/City

OK, it is based up on my driving, but not in way that accurately reflects my actual driving.

Sadly both The Haunt and The Nine's are gone.

Again, I don't think this confuses me. It just has been horribly inaccurate, at least for my driving situation.

Well, at least it is not just happening to me so that makes me feel a bit better.
It’s happening to all EV’s around the world as we speak except for the LFP Tesla Model 3.

Also, there is an expected 10% degradation in the first couple of years, it could come sooner it could come later.

Lighting rated= 320
10% degradation= 288
90% Charge= 259

Then take into account cold weather and those ranges drop. In my case I have seen 10% range drop because of a Front lift, wheels/tires, and weather change. Before that I was at 250-260 with Warner weather and hilly terrain on my daily drive. I have never reached the Ford claimed range on 90% or 100%

There are so many factors with range that you can’t exactly pinpoint what’s causing it. I haven’t seen a case yet where any manufacturer has changed a battery packed because of severe degradation but maybe I am just not looking in the right places.

Again, my complaint is not that I am not getting EPA range. My complaint is that I have seemingly been getting close to the EPA range based on my calculations but the range estimate is always way lower.

As i’ve been saying, the GOM creates more problems than it solves. OEMs just need to scrap it.

This ^^ is correct.

Another reason why I don't stress with the GOM.

I leave my screen in calm mode so all I see is a "fuel gauge" without all the extra information I don't need.

As others have said, the GOM is actually a Stress-O-Meter (SOM) for some...

For background purposes, I drove from Lake Tahoe, California to Missoula, Montana in mid September, round trip. Upon return, I parked it and drove it once from Lake Tahoe to the SF Bay Area to my office, and back to my parents house (2 hours from office) where it is parked and waiting for my next trip to the office. No freezing temps during any of this. It doesn’t look good! I’m not worried, because if something is wrong, it’s under warranty.

I was driving an average of 65-70 miles per hour on these trips.
