Current max miles in the GOM

[sglewiswl]

What's the Max miles any of you are seeing at 100% charge on the GOM. I'm curious mostly, and yes I know it highly variable based on temp.
My 2021 Select standard battery AWD with 94.1 % SoH just gave me 215 miles. Most I have seen since I purchased it used in October.

'22 GT

I've seen 270 on occasion, don't recall seeing higher, and often see 257. IIRC the window sticker shows range at 260.

Local driving I've been seeing ~3.5 m/kWh, which should translate to ~318 range in town. Interstate is much lower.

Reset driving history and you should see the range in ideal conditions

'25 AWD premium with under 700 miles showing.
Window sticker says 300 mile range. Socal temps ranging from 60 to 80 degrees.
270 is the most I've seen.....suspect the dealer left the battery charged at less than 10% for several months before purchase. Possibly hurt the battery....

This is where the GOM is bullshit. Your battery has a max charge based on the original size of the battery and the current SoH, it needs to dream up a miles per kWh based on past driving, but wait it was 30 yd today its 60. Lately as the temps rise, every time i drive the car the % goes down but the miles go up. I am curious if there is a better way. I believe some of us should be able to enable an expert mode and see more real-time metrics.

I routinely charge to 70 or 80%. I very rarely charge to 100% and when I do it is on either a 4.5 or 7.2kW EVSE (I think 5x) since the car was new. At 80% I take the GOM number and divide it by the reported SOC. Typically in the winter in Portland my 2022 GTPE would calculate at 240-250 miles and in the summer that calculation would be closer to 270-280. During the summer I would calculate over 290 miles on occasion.

I rarely use DCFC, but when I do I try to stop it by 80% and try to never go below 30% most of the time. My battery health is still showing at 94.5% as it has for some time now.

On the road trip back to Portland with sub freezing temps I would typically it calculate about 175-190 miles if I was charged to 100%. The car now is up in Portland most of the time where it lives in a heated garage in Portland and it has never seen snow - but it has seen sub freezing temps.

But just before I left LA this past January after a month back in Los Angeles with a majority of city driving and warm temps I did charge to 100% just 5 mins before we departed...and I was shocked that the GOM read a shocking 312 miles!!!

But I agree-with sglewiswl the GOM is just a wild guess based on factors (temp, last several drives being the biggest influences) that are not really a good predictor for what you will get. But was shocked to see this on a GTPE with almost 31K miles.

And I'm not being a hater. I love my EV and totally get that it is highly variable, but my wife thinks I'm crazy giving her the play by play of the GOM. I think we would better served with a gouge of current capacity and calculated miles based on several scenarios. Like its cold today, mileage will be lower, or hey its sunny and 70 drive away. EVs are not in the foreseeable future be able t solve this. Quit lying to us.

I don’t think it is a lie…it is just a number. I have been driving EVs for 27 years. Until 2011 there was no GOM.

The only thing that really matters is the SOC- and the driver knowing how they will be driving (mi/kWh). Cruising at freeway speeds with 4 people and the AC during the summer in the mountains will be very different than casual driving in slow traffic (what I often do when I am in LA) vs aggressive driving etc.

Just knowing how the efficient the car will be under whatever driving condition and knowing the SOC is what matters.

The biggest battery in a Mach E is 91kWh. That is the energy equivalent of 2.7 gallons of gasoline (91/33.7kWh per gallon). How you drive and what conditions you are driving in only the driver knows…the car can only Guess (o meter)what you are going to do based on what you have done recently and the conditions that the car is in.

There are far more variables in an EV than an ICE- and the difference is dramatic based on how you drive and the conditions you are in.

The only guide I really use is mi/kWh and my SOC. I know what it means when I am getting 3.5mi/kWh or if I am getting 1.9mi/kWh on that charge- and how far I am going to go before I charge next.

I just know for daily driving, an EV is all I will drive and now I can go anywhere I want to go because there is now enough infrastructure to do that. That was not the case even 5 years ago, let alone 27 years ago.

The only thing that matters are the kWh available. Cat Scanner shows that. Got down to 3% on a trip last week with the Lightning. 8.64kWh. Truck said I had 8 mile range left. But, at 1.8 miles per kWh, I had 1.8 x 8.64=15.6 miles left.

Seem to recall something like 385

If it said 285 I’d find it hard to believe I would achieve this is any ambient conditions

I think you lack the understanding of the capability of the range projection. If you want the most accurate projection, put a destination into the navigation, and start driving. It immediately adjusts, pulling in all the current factors.

I parked last night at 60 degrees. It was 40 degrees this morning. Car is in a garage that is 50 degrees from yesterday's heat. The car has no idea, sitting there, that's it 40 outside, nor does it know that today's forecast is 60. Nor is the battery 50 degrees, since the car was driven yesterday it maybe was 70 on shutdown, and has cooled to 60.

Now, I start driving with a destination. The temp probes get current air passed over them, and the car gets that data. It knows where I am going, the roads, and current conditions, and adjusts.

 

[25_SW_GT]

My 25 GT has only been charged at home (L2) at 35amps to 90% since I purchased it new in November. Never been on a DC fast charge, unless it was done at the dealership prior to taking delivery w/only 8 miles on the odometer. It does vary with temperature, of course, but regularly shows between 235-245. Twice the GOM has shown 255, both times the morning temps were in the mid sixties. It is daily driven on a 85 mile commute, and as of this morning, has just over 6K on the odometer.

I think you’re crazy giving us the play by play of the GOM. You are talking like someone who’s only had the car three weeks. Just put a piece of tape over the GOM, look at the % of battery, look at the weather and where you plan to go, and say to yourself, “It’s cold today, mileage will be lower, or hey its sunny and 70 drive away”.

Fast charging has zero impact on the GOM.

We have the best GOM I have seen on any EV. If its local use, dont look at it, just drive. If its highway, use your nav and the car factors in all of that, Temp, speeds, wind, altitude.

21 SR AWD just like you, owned it 4 years, has always been consistent for us. Its our highway/roadtrip car, vaction, we take it everywhere. No need to give everyone (the wife/passengers) the play by play, these forums are the only people who care about this stuff!
