Mileage understanding

[Fortunete11er]

Hey all,

I've read some of the threads on mileage and things are not to clear, so need some simple clarity. Purchased my 2024 Platinum in September. My understanding is that I should be getting 300 miles (or a few more) on a 100% charge. BUT.... When I charge my truck to 100% I have gotten 296, then 287, then 276 then 268. So my understanding is the computer is taking into account some other variables to give me my estimated mileage. I don't give a care about that, I want to know that regardless of what it says I will get 300 miles on my 100% charge?

Why doesn't the computer give you the estimated mileage on 100% period and then another screen or another setting give you the estimated mileage with all the variables?

No, you will not necessarily get 300 miles on a 100% charge.
Your range depends on many factors, mostly driving speed and
acceleration rate.
Your predicted range is progressively dropping because your driving history (mi/kWh used) is less than the EPA average that advertised range is based on.

Right,

Lets assume I am driving perfectly per the manual and "I should" get 300 miles to 100%. I understand variable like speed and all the other stuff (that effects ICE cars to) and I'm not really talking about that.

My perdicted range on 100% charge the other day was 249 I think. OK. BUT regardless of what that says I should still get 300 miles on a 100% charge, correct? I really don't care about the predicted mileage based on .......

And outside temperature and whether you are using accessories such as heat or AC.

This is an interesting thing to say.
Because the computer is telling you the ‘variables you don’t give a care about‘ are, in fact, effecting your range. Disregard or denial will not change that.
Why do you believe you should get an arbitrary “300 miles” from a 100% charge, regardless ?


You can always determine your range by multiplying your average mi/kWh by remaining battery capacity.
Remaining battery capacity is battery % x 131 kWh.
But don’t waste your time, it’s the same calculation being displayed to you .

Let's look at it like a gas car

You have a 20 gallon tank. On the highway you get 20 miles to the gallon. You can drive 400 miles

Now you go drive in the city, but you only get 10 miles to the gallon. Would you expect to still go 400 miles?

If you drive the government testing cycle highway test, which averages 48 mph, and doing so in the summer on a nice clear calm day, then yes, you should get around 300 or so miles.
Is all of your driving at 48mph on nice clear days? If not, and you drive faster, or use the AC, or worse the heat, or it's rainy, or it's windy, or your tires are at a low pressure (aka, the real world) then you won't get 300 or so miles.

Bottom line, no, you won't get 300 miles if you charge to 100%. You don't put miles into the truck, you put a quantity of electricity. If you use that electricity faster than normal you will get less miles, use it slow than normal and you will get more miles.

Because they designed the screen as they are, we do have a TRIPS data screen which breaks down the percentages of energy for four categories, that's the most you'll get from Ford Motor Company.

Lets use your analogy, and I'll use real world. I have a goldwing as my primary vehicle. It has a 6 gallon tank and I know I can get 40-45 miles to the gallon, I know because I have driven it to 240+ miles. This is my starting point. SO, I know I can always get 240 miles on a full tank.

So every time I top my tank off I will get 240 miles. Now that is effected by rain, wind, co-rider, trailer, etc. (within that 240 miles), But lets assume I am by myself, when I top my tank off again, I know I can get 240 miles.

This is my point, everytime I top my tank off my starting point is always 240 miles.

But for some reason the computer in my truck is telling me everytime I top my battery off to 100% I will NOT get 300 miles I will get a different value each time and each time it is always lower. I want to know if 300 miles like Ford and the EPA is my 100% starting point

When I got my truck in September I got 299 miles to a 100% charge and now I get 249 miles to a charge, I don't want a average of my driving habits, I want to know what estimated mileage will be on a 100% charge each time I top off the battery. That is my point.

What is distinctly different on 9/1/24 & 12/27/24 in Virginia, that members have given you a clue as to an impact on predicted range?

You don't fill your truck with miles. How many miles you can drive is, and will always be, an average of your driving habits. You cannot put "300 miles" into your truck, you can only put a quantity of energy, how far you can go will always be the mathematical equation relating your energy usage with the quantity of energy you have available. That IS what it is showing you. It can't show you that your range is 300 miles, because it is not. Your range is the mathematical calculation of previous efficiency and the quantity of energy in the battery.

Put another way, your truck will go 290 miles, or 240, or 350, or maybe even 200. You DO NOT IN ANY WAY always have "300 miles" because you don't fill it with miles.

As for your goldwing, no, you cannot ALWAYS get 240 miles. Usually. But not always. And that is the point we are trying to make.

And in reality, do you want it to show you 300 miles if you cannot ACTUALLY go 300 miles?

It is significantly colder. The Guessometer takes temperature into account. And if you punch in a trip, it will take the route into account as well (and tell you it has revised your estimated range).

I want to know what estimated mileage will be on a 100% charge each time I top off the battery. That is my point.

If your consumption of energy is about 2.4 miles/kWh, you got your 300 mile range regardless of what is shown on the GOM at that time. If it drops below 2.4 it is up to you to make whatever changes are within your control to get that average back to 2.4 if you want your 300 mile trip. The GOM takes into consideration your past driving practices as well as what has been explained above and guesses your not going to make it.

@Fortunete11er I got my Pro ER in September of last year, just in time for the cooler temps, and therefore, lower estimated range - similar to you.

I think you’ll be pleasantly surprised when the spring/summer comes around with its warmer temps. Your efficiency will probably jump a good bit, adding to your overall range.

I don’t mean to come across as rude so forgive me if I do, but I think you’re just overthinking all this.

All said, give it a full year before you start to worry. Everything you’ve described is normal.

Ok, I think this is the answer that I was looking for. Im not really interested in my truck telling me my driving habits,

Sorry for beating the horse, but as a fellow motorcycle enthusiast, Harley Davidson didn't promise me I could always get a specific range for the 6 gallons of gas when the tank is 100% full.

I ride in variable conditions, I stop for energy when its called for, not when the tank runs dry.
