99 miles discrepancy in Mileage.

[Tebbo]

I have the AWD extended range advertised as achieving 335 miles. After charging to 100% the mileage is displyed as 236. I knew 335 was not realistic from reviews but 236 would almost suggest that I have the standard range battery in the vehicle.
I have contacted Ford and am waiting for their comments but just wondered if the answer is already out there.
I am sure this has been raised before but I couldn't track it down so apologies if thread is duplicated.
Thanks.

Very very very touchy subject around here!!!! lol

Take a look at the below post. Its an electric car, looks like you are in the upper 40's for your highs. That is enough to cut range well past the 99 miles.

Also keep in mind, the meter you are being shown is only an estimate. That meter will change a lot as you drive the car, and the longer you drive it "should" start to get a little closer to the correct range.

Hiya

We see someone post something like this about three or four times a week on this forum - which is why people get a bit tetchy when it comes up again and again, and again LOL

The post that @Kabish pointed you to is a good start - but I noticed that something's not quite right with the post layout so its white text on a white page. ?

I can see you're in the UK - come say Hi in the UK thread there. The UK models are a bit different to the US ones, so you'll get more region specific answers over there too.

But to answer your original question in one sentence... there's nothing wrong with your car, you don't need to contact Ford, electric cars do less miles in colder weather

Ford did send an email out to UK customers the other day as I think the dealers are getting bombarded with the same questions - I've linked that here

I'm pasting the text below that's invisible in that other post....

Hello, it looks like you are new and might be complaining about your cold-weather range decrease without having referenced the numerous threads on this subject. Due to high volume of questions, this is a pre-written response to help alleviate your concerns. Remember to use the search function before creating a new thread, as forum members are fatigued with new users asking this same question over and over again almost daily.

Range decreases due to cold weather, the range display is a highly pessimistic guess not to be taken literally

First, understand that some range loss in cold weather is normal due to the laws of physics. Chemical reactions in the battery are more sluggish, the air is more dense to push through causing more drag, and your heater takes more electricity to run than A/C. The colder it is, the less your range will be because of these factors.

Second, know that the range you see on your display is just a guess. It can be off 40% or more from reality on some software versions. Do not take the number literally or you will be upset, nothing is wrong with your car. Unlike other brands like Tesla, Ford has made the reading extremely conservative and sensitive to cold temperatures on purpose, so that you don’t strand yourself in cold weather. Expect a sharp decrease in the reading in temperatures below about 50ºF/10ºC that is greater than reality.

Third, be aware that software updates have been released that increase the accuracy of the range display in cold weather significantly. If you haven’t had software updates done at your dealer yet, you should consider doing so because you are missing out on a lot of improvements (CSP 21P22 released Nov 22, 2021). After the update, you may see up to 30% more range displayed even though your actual range is unchanged.

You can calculate your actual range yourself by simply noting the battery percentage before and after a trip greater than 20 miles. For example, if a 25 mile trip took 12% battery, 25/.12 = 208 mile range at full charge. Another method is to multiply your mi/kWh efficiency by your battery capacity, either 88 kWh for extended range or 68 kWh for standard range. For example, if you are getting 2.6 mi/kWh in an extended range, 2.6*88 = 229 miles of range. Please note that in cold weather, the actual capacity of the pack will temporarily decrease some, so 80/62 kWh may be a better capacity figure to use for an estimate in cold weather. Full capacity will return next summer with warmer temps.

The amount of actual range loss may vary due to many factors, but to provide a generic reference, a loss of 35% at 20ºF/-7ºC would be typical in average driving. This would equate to a range of approximately 176 mi / 137 mi for extended/standard packs. The percentage range drop compared to summer is also inversely proportional to the speed you drive due to the heater’s percentage of total energy use. If you drive in a city you may see a 40% drop in range, vs. a 25% drop driving on the interstate.

In summary, remember the range display is always a pessimistic guess, and your actual range will be greater than indicated. Remember to get those dealer updates done to increase your satisfaction. Parking in a garage, plugging in, and using departure times will help keep the battery warm and increase your actual range. Enjoy driving your electric car after gaining an understanding of normal cold weather range loss and the pessimistic guessing of the range display, affectionally called the GOM (Guess-O-Meter).

This comes up all the time. The cold weather affects efficiency, and the range estimator (guess-o-meter) generally overcompensates for the cold. Your range will be less than the WLTP estimate in the winter, and likely higher than the estimate in warm weather. This thread talks about how to more accurately compute your actual range, but the causes of the issue in the first place:

1. Because the car doesn't know how far, how fast, in what conditions, etc it cannot be exact unless you actually put in a route right then - and even that is an approximation based on modeling. Thus the GOM is intentionally conservative as a "worst case" scenario to prevent people from getting stranded because the GOM said they can go farther than they actually can. It tends to be more conservative for this very reason; Ford has been underpromising and overdelivering on the Mach E. While that confounds newbies, doing a little research results in recognizing the issue and not being alarmed by it. By contrast Tesla overestimates their range on their GOM in all conditions; see plenty of actual "real world" driving tests by insideevs, alexonautos, edmunds, etc.
2. ICE engines are only 30% to 40% efficient, with the majority of energy being lost as heat. In winter that is an advantage because the heat that would otherwise be wasted is used to heat the cabin. BEV's are by contrast 95% efficient with minimal energy lost as heat. In the winter the car has to use extra energy to heat the cabin. That is why they tell you to use the seat and steering wheel heaters instead of heating the cabin if you can, because there is a lot less to heat up. The chemistry of Li-ion batteries is to blame as well: the liquid electrolyte loses viscosity (and thus potency) as temps drop well below freezing. At 30 to 40 degrees F it is minimal, but once you get down to around zero or below it becomes an issue. The 2 factors (no waste heat and chemistry) combine for some loss (10% to 20%) in range once it gets down to freezing or below. Therefore in really cold (-30 degree) temps like in Alaska the car's actual range does drop by 40% to 50%. In more reasonable climates (20 degree temps) effective range drops by 20% to 30%.
3. You CAN compensate somewhat by configuring departure times and leaving the car plugged in; this will warm the battery and the cabin using grid power. You can also remote start the car for an impromptu journey, but that doesn't necessarily warm as much as a scheduled departure.
4. EVERY BEV experiences this issue right now; it is not unique to Ford. That is one of the reasons they are all investing so heavily in solid state batteries: "dry" batteries do not experience the issue with the electrolyte in cold weather.

Yes, as others have stated, many threads indeed. Something else though is that you’re in the UK with the advertised range for the UK. I assume your car is programmed in accordance with that in the GOM so that it may actually say 335 in perfect conditions, but I’m not totally sure. That same battery gets an estimated 270 miles in the US based on our government’s testing standards. In cold weather - 40 degrees ferenheit - people get about 170 miles or less. I drive mine like an ICE car so I’m running the heat, doing a remote start for a few minutes to warm it up, and I don’t precondition the battery, so I can get as little as 1.4 miles per kWh which is about 123 miles on a 100% charge, especially if it’s in the 30’s Fahrenheit (0 Celsius).

I have the AWD extended range advertised as achieving 335 miles.

It's not actually advertised as achieving 335 miles. It's WLTP rated at 335 miles. Those are very different things. I'm not sure any EV has ever achieved its WLTP rating in normal driving, and certainly not in the winter.

 

[Motomax]

You got the double whammy: Unrealistic European range ratings and cold weather loses.

I have a standard battery with RWD and in the last 9 months have never had the guess-o-meter show more than 215 miles.

Let me add that in my decades of owning ICE vehicles I've never once had a car that has the MPG shown on the sticker. It's always lower. So, why should this be different with an EV?

Can we get 2 pages of screenshots from FordPass showing range and more copy paste spam from the cold weather thread hawks.

This forum needs moderators that actually do something. The replies are just as bad as the OP. 1 Person should link to a thread and done ... closed, move on.

I recently received my RWD extended battery - sticker says 300 mile range. Has not charged above 225 so disappointed. As a previous EV owner I am fully aware of mileage estimates, however my Leaf charged to 100 miles - then if I burned heat or AC the mileage usage exceeded the distance.
I was expecting to charge somewhere close to 300, will have to take some logs for actual miles vs the estimated.

Not sure about the cold weather comments but I'm in Denver it's not that cold. 40s is not cold so if a battery cannot take that I don't know what to say. Previous EVs and hybrids have been fine with near zero temps just burn miles from using the heater.

Update to my previous post.
After I contacted Ford they referred me to the dealer.
Today I took the MachE in with a full charge showing a range of 229. After a software update the vehicle now shows 299 which is a great improvement.
I also took my Kuga ST Line PHEV in today with a full charge showing 21 miles. After a software update it shows 36.
You can draw your own conclusions but I feel more confident that the vehicles are now displaying ranges in line with what might be reasonably expected.
Both updates were done free of charge.

Fun fact - they updated your driving history. Your range is the summer range. It will drop like a stone by next week.

All that matters is what miles (or kilometers) you get per kWh. Take that, times the battery size, and you have your range.

 

[kltye]

I don't understand why people are so resistant to facts about how the GOM works. Like, are you being willfully ignorant? Are you thinking we're lying to you? Or are you literally unable to accept a different worldview after you've established in your mind how things work?
