Frustrated with Guessometer

[Martin Volken]

I am trying to understand the guessometer, but it makes no sense to me.
I own a 2023 Route 1 which is supposed to get a range of up to 310 miles.
I have never been able to get the Guessometer show more than 280 miles of range.
I recently drove across two mountain passes and back for a distance of 120 miles each leg.
Both ways it showed a battery usage of 35% and and an average 3.7m per kwh.
That seems to make sense, in fact it even seems better than advertised.
Now I charged it up 74% and the guessometer gives an estimated range of 168 miles, which is ridiculously low.
Any ideas?

Its just that a guess based on previous drives, outside temp, current temp of battery. If you use the ford nav it tries to guess based on the mapped route and may lower the range based on hwy speed limits, mountains etc. Best way to tell is to do what you did and watch the mi/kwh. Anything 3+ is going to get you close to the estimated range.

The EPA rating of 310 miles is not a guarantee of the range you will get. What it is the result of a standardized test that every vehicle undergoes, whether it is powered by electricity or gasoline or diesel. It is meant to allow you to compare similar vehicles to eachother and see which one is more economical to operate. For EVs, this is generally expressed as miles per kWh, or kWh per 100 miles. The range rating is almost an afterthought In the results.

In other words, the estimated range you see in the guessometer is a reflection of how you have been driving in the past, and is constantly updated as you drive. The more you drive, the more accurate the guessometer will become.

Did you protest when your gas vehicle didn't get the EPA range?

Any ideas?

Try to reset driving history. After a few driving-charging cycles it might get more accurate.

When it comes to the GOM, there are 3 choices: 1) Accept that it is a guess and can be wildly inaccurate at times. 2) Obsess with it and let it drive you nuts. 3) Ignore it.

There's another choice...

Accept the GOM and redefine your concept of distance to fit within the fluid predictions of the GOM.

That’s another way to state my #1. Sort of. ?

What you need to do is drive based on the %, not on the miles expected. The % is going to fluctuate based on the parameters already mentioned.

For example, I drive mostly around town, my MME says I can go 174miles but I have 74%. I know I can probably go 200 miles but my GOM is still basing mileage off the last trio I took from HTX to ATX where I was traveling over 75MPH and used a lot more energy. I can either reset the Trip Meter or let it correct itself as it receives more data. So, I just keep my eye on the % and not the miles.

Did your last car have a guess o meter?

Mine have for years (gas cars) and they never stated the EPA range either…….. because I didn’t drive like they did in the EPA test.

This one is no different.

I pay attention to mine just for the fact that I know how far I might want to drive before I start worrying about charging up for instance, yesterday I charged up to 100 it started out at 263 5 miles down the road I was at 2:40 so I’m going mostly with the percentage, but I do watch the mileage .

Actually, both of my last cars had a GOM. Most modern cars with a computer on the dash will give you a range estimate. The difference is that the known range of the car is so much higher and the gas stations are plentiful. Range anxiety is not a factor in ICE cars. The GOM on our cars is there to help you not drive past your options.

They keep changing how they calculate it. I wish they would leave it alone. I just get it figured out and they change it again

I don't understand the first part of your statement, the person you were replying to also said their gas vehicles had them, that was their point.

As to the second part, EV charging is plentiful and range anxiety is a personal choice, not a requirement. We have owned even recent gas vehicles that don't have ranges with a full tank of gas much further than 300 miles. We had a 2019 Ford Escape with an ecoboost engine and a tiny gas tank and that thing was rarely much better than 300-400 miles.

EV chargers are everywhere. They are at gas stations and grocery stores and parking garages. They may not always be the ideal charger, like a Level 2 instead of DCFC, but there are few places left in the US where your odds of being stranded are high unless you are pushing it to 1% before finding a charger.

Before the MME we had a Focus Electric that only had 130 miles per charge at best, and we never came close to running out with it either.

All that is to say, the GoM should be ignored for the most part. Use it as a reference if needed when you're down to 20% or so, but otherwise rely on percentage just like I believe 90% of ICE drivers rely on fuel tank level and not that GoM when determining fuel stops.

I know more people that have run out of gas on the side of the road than EV drivers that have had their cars die because they couldn't find a charger. It's absolutely a choice whether you let it control your ownership experience.

For me because I don’t travel, but I feel bad for people that are traveling. Let’s say from Atlanta to New Orleans for instance, right now we have an Electrify America station here in GULFPORT that’s been down and it’s gonna be down for probably a total of about 4 to 5 months and vapor trails on the for here, there’s really nothing between Mobile and New Orleans. I mean level two charging is ridiculous. I mean you really have to go to a casino if you’re traveling West it’s kind of a crapshoot, if you don’t charge up around mobile, AL you’re gonna have some anxiety, unless you have the Tesla adapter, I left Tesla out they do have one in this area called D’Iberville, which is just before GULFPORT off I 10 but you’re gonna have to have an adapter.
