My range seems really low!

[EdY]

I don't understand why people believe an EV GOM will be any more accurate than an ICE range estimate. My wife's car (ICE SUV) has a prominently-displayed range estimate. When she leaves the gas station, it says 320 miles, although she ends up getting 270-280 miles max (even less in the winter).

It's because of the current state of DC fast charging. If there were a fast charger every 10-20 miles along the highway, noboby woul care about range. It would only be a question of how long do I have to wait to charge. Alas, we are not there yet, and so everyone has range anxiety.

I also got a GT PE, and live in Minnesota. With the 20 degree temps I am getting 2-2.3 miles/kwh. Even in the early fall when I got the car,(temps in the 70's) I was getting about 2.7, which meets the hwy range of the car, i.e. (235ish miles), but doesn't surpase it. I would never even get close to 260 on the highway going 80 miles/hour.

Before anyone makes a comment, I never look at the GOM, I just do some simple math while I am driving to see how many miles I am going for every 10% of battery capacity. Right now, that works out to 19miles per 10%, or 190 for a full pack driving 67ish miles/hour. Note that I only check range when I am road tripping and on a highway. Otherwise I really don't care.

What I do care about is the garbage data that the ford pass app gives me for my trips. It consisently over estimates miles/kwh compared to what the car calcuates. On my 80mile trip back from my son's swim meeting, the car claimed, 2.1 and the app claimed 2.3. The car was right, the app is wrong.

I have also seen where even the car is wrong. That or my battery capacity is not 88 kwh. This is my biggest complaint about the car. With the data provided by the car, it is impossible to track battery capacity an how it changes with time and milage. Makes it easy for Ford to avoid battery wananty issues when noboby knows what their capacity really is, and how close to 70% they are.

Maybe this doesn't matter to some/most people, but I keep my cars for the long haul. I plan on using this as my daily driver for the next 10+ years.

To me it seems that even the car likes to cheat a bit when it comes to consumption. Yesterday I had a nice 200km(125mile) drive with an average speed of 90km/h(55m/h) for the whole trip. The car told me that it used 22kw/100km’s, unfortunatelly when I calculated it from the SoC used the real figure was 25.9kw/100km’s. I got used to ICE vehicles cheating on the consumption but it seems mach-e is no better on that. Still love the car though

Interesting. I wouldn’t have thought the numbers would be that far apart. It’s almost like the 22 includes propulsion only.

BTW - if you don’t mind my asking - where in Finland are you located? I spent quite a bit of time in Tampere.

Kiitos!

I don’t mind at all, especially when it proves how small the world is . I live just 30km’s out of Tampere, and work though Monday to Friday right at center.

Back to the topic of consumption, so far the figures have been quite close to the truth,ie. this morning I used 19%SoC in my morning commute of 50,5km, the car told me it used 25kw/100km and 19% of my SR battery is 12,9kw so this time the error is in easily acceptable range.

The SOC-based calculation is not so simple, because in most EVs the % SOC is Ah-linear, but not kWh-linear.

Not sure about MME, though. I hope someone will eventually compare Ah vs. kWh consumption at each 10% (while driving 100% to 0% SOC) to establish the linearity of the SOC scale.

Kia/Hyundai EVs have hidden counter for Cumulative Ah charged/discharged, which can be read through OBD2 port. But there's no Ah counter for MME in Car Scanner app. Maybe Forscan or FDRS can read cumulative Ah charged?

spent some time in Vaasa several years ago. great country.

That would explain some of the error because the morning commute starts from 90%SoC and ends between 67-75 %Soc depending on the outside temp etc. While on the other hand that 200km trip started from 90%and ended at 14% giving it a lot more room for errors to occur especially when not taking in to account it propably counts the SoC in Ah’s

I picked up my GT in November and since then the GOM has never displayed anything even close to the actual range of the car. I have ignored it from day 1. But that is because this forum has educated me and unfortunately there are a lot more MME owners than forum members. I can understand the frustration when you bring home a new car and the GOM says 215 miles of range on 100% charge when you expected the EPA range of 270.

I have noticed a huge difference between the FordPass EV driving history and the car trip log. I think maybe the EV driving history is the most accurate. On a recent trip it said I had an efficiency of 3.2 mi/kWh which was a lot higher than the car trip log. At first I thought it was too high but the kWh used was very close to what I calculated using the % battery used if you assume at 0% you still have 2-3 kWh of battery remaining.

I wish the trip log and EV driving history lined up better because the vast difference makes me wonder if any of it is correct. It makes me wonder if I can really do anything reliable with the mi/kWh efficiency provided by the car trip log.

Maybe the trip log is just as accurate as the GOM, which means none of the data provided by the car is helpful. Really. That needs to be fixed. In the meantime, I still love my car and I have never had range anxiety because of these issues.
