I’m propably poking a hornets nest here but am I really the only one here who thinks that the GOM is actually quite accurate? It usually starts a bit on the positive side for me(maybe 5% over from what I’m really gonna get out of it) but quite soon it adapts to maybe 5% less than what it will be in real life. It’s been like that from day one for me, and I’ve been driving it for 10000miles now in the past 4 months.
I don't doubt that it's fitting better for some people's situations than others.

For me, I have almost 14k miles now and my lifetime MPK (mi/kWh) shows 3.0. With the 88 kWh (usable) battery, that calculates to 264, so nearly right on the 270 EPA range. But my GOM has never made it to 270 (extrapolating to 100% SOC). For a few weeks in July it got close. It showed 268 at my peak. But the next week (still 90F+ temps), it went back to about 245 (I suspected an OTA came in and reset the drive history). The GOM commonly stays in the 220-250 range for me, with occasional drops to ~200, and then that bizarre one-time reading of 167 (again, all after extrapolating to 100% SOC).

How I wish I could see those kinds of MPK's :D, at the moment with the temperature going anywhere between -10 to -20°C I usually get around 2.0-2.2 MPK. The funny thing about all of these figures is that here in Finland the car was sold with 440km/100%, however even in late summer the best I got out of it was around 355km/100% and now it's around 230-240km's. Because I always start my journeys from a nonheated carstorage, GOM estimates I'll get around 270km with 90% SoC but after driving around 10 km it corrects itself to around 210km with those remaining ~85%SoC

First, let me say I love my Ford Mach-E....I'm literally stopped in the street by pedestrians and drivers alike to admire the car! However, I'm in a battle with the Ford Service organization, because I bought the Extended Battery, and not once has it reached 270 miles on the range display. It says it's a 100% when it hits 213 miles. The highest it's every shown after several days of charging in a warm garage is 238. Service keeps talking about reduced range during the winter, which I totally understand...but why won't it reach 270, and why does it say 100% at 213 miles. Please help, this is extremely frustrating and I don't want to file suit, but I paid a lot for this car like all of us did, and I want every mile due to my long commute. Thank you
I’m in Coastal N.C and during the Summer months when I occasionally charge to 100% I have gotten as much as 317 miles. This Winter, my first with the E, while not real cold here, (40 degrees is cold) a couple of recent 100% charges netted 270 miles. Since I don’t travel long distances in the E, I’m happy with this. And charging with my local EMC’s suggestion of charging my EV between 11:00pm and 5:00am I’m charged .10 per KWH.

As you can see from a recall note, it appears Ford knows this is an issue (at least for recalled Mach e's that need windshield and overhead moonview replaced. Note that they say "Ahead of future Ford Power-Up over the air software releases, we have authorized our dealers to perform several customer enhancements, including the following: improved range in cold weather, DC fast charging, range accuracy, etc.

Where were you seeing the above notification? (FordPass app, ford’s website, on your car screen?)

bought our GT on 12/3. It says I have all updates when I checkin my car’s screen but your notice is after my purchase.

Your GT is probably up to date if you didn’t get the notice about 21P22.

@Malfy34 the GT line doesn't have any updates pushed out OTA for it as of today and there are no programs eligible for updates from the dealer. To answer your question, the picture that you asked about is from FordPass. You might get a notification for the rear seatbelt anchors depending on when your GT was manufactured.

@ManInBlack the GT vehicles are not eligible for 21P22.

Yet another take on the answer to your question:
Yes the dash should show 270 miles at 100% state of charge. But only if you follow the EPA test-driving guidelines:
1. Drive only indoors on a dyno in a climate controlled environment at 70-75° Fahrenheit with no winds.
2. drive 50% of your time in stop and go traffic mimicking stop lights and signs. For this half of your driving don’t exceed 40 MPH.
3. Drive the other 50% of your time at 55 MPH with no elevation changes.
Driving in an uncontrolled environment, faster than 55 MPH and not spending enough time doing stop and go will greatly effect your dash display. Also driving outside in different temps at different elevations will effect the dash display. Going fast (over 60MPH) and being cold (below 80°) are two things that will tax your battery the most and cause your dash displayed range to go down.
I think the Mach-E, like me feels like anything below 80 degrees is cold! Lol

It does. Anything less than 80 and it starts turning on the heating blanket around the battery. Although all the peeps with the fancy OBD scanners could probably tell us EXACTLY what temp the MME defines as cold.

I have replied to this thread once before and now have another comment and some data points

I bought my Mach E 4X on 19 November 2021

- 3,000 miles on odometer now,
- according to trip meter, I average 2.4 miles per KW over the 3,000 miles
- I live in west central Michigan near grand rapids
- very few days above 40f since I bought.
- past month, most days below 30
- past week lots of snow and most days in high teens and 20s
- I commute 23.5 miles (one way) 90% highway miles to work daily.
- I keep speed to 70mph 90+ % of time.
- I do NOT skimp on climate control. I put it to a comfortable 71 degrees on AUTO.
- I keep and charge and precondition car in garage over night but it must sit in the elements for 9 to 10 hours every day at work, not plugged in.

I acknowledge the 270 estimated range is done on regulated conditions not likely to be repeated in the real world. (Dyno, 72 degrees, most city driving cycles, and highway speeds are under 60MPH)

interesting observation from my window sticker is the 100miles per 37kw. This would suggest only 2.7 miles per KWH and with 88 usable kWh, would only be 237 miles of range.

I wonder why the difference on the window sticker with the 37kWh per 100 miles and the 270?

but, thus far I’m pleased with my average of 2.4miles per kWh. That suggest 211 miles of range in this cold weather, which is “only” 22% degradation from “estimated perfect condition 270 range.

really looking forward to spring and summer to see how it improves.

Ford Mustang Mach-E Shouldn't my Display read 270 @100% EB6A7988-B0E1-43E8-ADBB-533268552BA9

My guess is that 37 number is calculated using the full battery size (98.9 kWh). Some manufacturers don't publish "usable" battery. EPA probably just uses the most consistently available number, which is full battery. 98.9 / 270 * 100 = 36.6 (rounded up to 37).

That is a logical answer. Thanks.

Some data some of you might find interesting.

- 24 miles one way to work.
- 90% highway speed , cruise set to 70mph
- climate control set to 72
- outside temp 15 degrees F
- car garaged stored and preconditioned before departure

- arrived with trip computer saying I made 2.1miles per KW.

- equals 11.4kw consumed for trip
- charging at home between 11PM and 6AM at 7 cents per KW = 80 cents for the trip
- if I charged at a charge point at 65kw charge rate would be 30 cents per KW = .3 x 11.4KW consumed = $3.42 cents for the trip

- in my 2019 Subaru Forester I averaged 27MPG.
- 24 miles I would have consumed .89 gallons
- gallon of gas today is $3.15
- my Subaru would have cost me $3.15 x .89 equals $2.80 for the one way trip. (Obviously Doesn’t include Maintenace cost for oil changes etc)

So, even in this COLD weather, with terrible miles per KW, if you can home charge (at 10 cents or less per KW) you are much better off (all other things being equal) in a daily cost per mile in the Mach E than a car similar to a Subaru Forester.

If you must charge on the road, at 30 cents for charge point, or higher speed charges such as Electrify America chargers (43 cents per KW) you are better off with the ICE.

Now, now long will it take me to recoup the cost of the home charge point charger and the 240v on a 60amp breaker??? Let’s just ignore that. :)

Or the extra 20 grand a Mach-E costs to buy over a Forester. :cool:
