To be honest, even that does not match up remotely close. I had reset my trip 2 because people said it freezes up and just sits on the same miles/kWh. I forget the number of miles, but I'm in the 100's and its showing 3.9 miles/kWh. I can also confirm on just about every day into work I park at 3.9 to 4.2kWh. I think one day I parked at 3.2 kWh for some reason, maybe heat, I dunno.

I 1000000000% am not getting 343 miles right now. In the summer time, absolutely, was very close to those numbers. Now that its below 70 degrees though, I'm doing lucky to actually clock 200ish in range with the ER Route1. Given the OP is dealing with +5 degree weather I could only assume his range will be in the 150-180ish range. I'll be honest, I was caught off guard by the drop at just 70 degrees. I did not expect to see a decent drop till I got into the mid 60 range.

WELCOME TO WINTER!!!!!! lol

Here is a screen cap on my phone as of right now. Estimating 222 miles, which in my experience is pretty much dead on. Last time I tracked it, it was off by like 15 miles. During the summer, this number is not even remotely right, but in the winter its been pretty spot on. In the summer it will be around 293 miles, where I typically will get 320-335ish miles.

Enjoy the new car and don't worry about the GOM. It will take a while and possibly a software update before it becomes useful. I have an extended range and used it in the snow for a trip to Fort Augustus. I recall on the way back my battery state of charge sat at 40% for about 20 miles (no hill involved). Things will settle but yes range will drop significantly in winter and if you can keep the cabin temp low and the heated steering wheel & chair keeping you warm instead on those long jounrneys that should help. Short journeys will of course impact range as the battery has to warm up as well as the cabin - just like on an ICE. Regarding pre-warming I find the car has a mind of its own but normally I find the car has to be plugged in for the cabin pre-warmig to operate.

In that event, congratulations! You’re in possession of the only Mach-e ever built with an accurate GOM. Be proud. Now that you know this, there’s no longer an issue with how far your car will go.

Also keep in mind that WLTP BEV range testing is even less accurate than the EPA range testing conducted in the United States. What you were told the cat would get range wise and what it actually gets are two very different things.

I did read the forum before posting but as usual it took someone else to post a link to what i was actually looking for. I did not realise that the GOM is highly inaccurate, I left the dealership with 100% charge and 284 miles on clock, i have driven 70 miles and am left with 100 miles on clock and 55%, so the GOM has dropped by 184 miles me only actually doing 70 and 45% battery used, that tells me i can do probably 80 miles on the remaining 55%, totalling 150 miles range, without anyone being a knob, i just want to know if that is the real potential expectation from a extender range awd model- get 150 in coldish conditions. I am probably asking repeat questions but i believe most of us new to the forum at one point or another would do
In your original post you mentioned you are new to driving a BEV. So am I.

When I first realized I wanted an electric car, I thought the published range estimates were for highway range, regardless of the weather. And I thought those published range estimates were actually accurate.

I didn't realize until after my last post that you live in the UK. The EU government mandated range test cycle for electric cars (WLTP) is really inaccurate. (https://www.wltpfacts.eu/what-is-wltp-how-will-it-work/). I mean, way, way off. Yes you can achieve 335 miles of range if you exactly follow the WLTP test cycle and in perfect climate conditions. Nobody drives like the WLTP test cycle. Well, I guess someone does, but she is old and can hardly see over the top of the steering wheel.

In the USA, our EPA has a test cycle that is reported by car manufacturers. That test cycle is also not very realistic, but it is much easier to achieve.

Your car is rated at 270 miles of range using the EPA test cycle. Many on this forum have been able to consistently achieve that range, but some have not. It really depends on how you drive. Nobody can achieve 270 miles of range highway driving at 75 mph, unless you are coming down the side of a mountain. That was a huge realization for me when I was learning about BEVs. I just assumed BEVs did better on the highway because that is how ICE cars are. Nope.

So your experience is understandably upsetting. You thought you were buying a car that can travel 335 miles before you need to charge again. If your average speed is 50 mph, you can probably achieve 270 miles of range, maybe exceed it. But if you like to push the go pedal to the floor, like I do, and you drive 70+ mph on the highway, your range will be less.

And then there is cold weather. Another thing I never thought about in an ICE car.

By the way, my mi/kWh average for the last few weeks is around 2.7 in cold weather, city and highway mixed driving. That equates to a range of just under 240 miles. I am happy with that because I know it could be much worse. Those crazy people living in Alaska know how bad it can be!

As for driving in the cold, put your thermostat on 67 degrees F, fan on low and use the seat/steering wheel heaters. I do that and it is very comfortable with a minor impact to range. If you like it warmer, your range will be impacted.

Yes, i am a bit surprised about the drop in range. I am currently averaging 1.7kwh and that was not exceeding 50mph for only 2 mile trip to work. My average since i got the car- last 80 miles os 1.9kwh.
I was hoping from a 335 range i will get an actual of 240 to 260 but that is not even close right now, maybe in summer.

That seems very low. How hot are you running the heater? Are you starting the car with the FordPass app? Preheating the car by starting remotely is awesome, but will hurt range unless it is plugged in when you do it.

Trip efficiency for such a short trip might be incorrect in the car trip log. How does it compare to the EV Driving History in FordPass? I have found the kWh used is very accurate in EV Driving History, while the distance traveled is often not accurate. I have also found the car trip log efficiency rating is usually not correct, either on the high side or low side. Mostly I have seen it is lower than actual.

You could purchase an OBDII bluetooth reader and using the Car Scanner app on your phone get some very accurate measurements regarding exactly how much battery is actually being used on your drive to work. https://www.carscanner.info/

Once you get past this situation, I hope you love your MME as much as I love mine. I look for excuses to drive it.

1.7 mi/kWh is extremely low, but I don't know the circumstances of your driving (temperature, speed, preconditioning, etc).
In the summer I approached 4.0 mi/kWh, and in winter I'm seeing around 2.7.

I am starting it with the start button in the car as the car is constantly in deep sleep mode so cannot start via the app. Temperature outside around +6 celsius, i turned heating off and it was still showing me that 30% of my energy went to climate. When i do have the heating on i have it to around +23 c fan2 or fan 2 dual. I chose long range as wanted to be able to travel to and from London with one charge ( 240 miles round trip) i guess it's early days, will monitor and see. I do have a phone call booked with Ford engineer tomorrow as i said i am getting very little mileage and the car is constantly in deep sleep. Hope he has some answers for me, otherwise love the look and drive so far. Just want to know how far i can actually get

The deep sleep and unable to start comment is troubling to me as a non techie and non engineer. My car has spent the past month plugged in in our detached garage and unused. I’ve been able to remote start it at will. I’ve also been able to schedule a departure for the car and have it precondition both the battery and the cabin temperature. Granted things are a bit different here as temps are probably around 7C overnight and 15C to 18C during the day.

Can you set up scheduled departures? And will the car actually precondition on that schedule? The more detail you can provide the engineer the better (I think).

1.7 mi/kWh is extremely low, but I don't know the circumstances of your driving (temperature, speed, preconditioning, etc).
In the summer I approached 4.0 mi/kWh, and in winter I'm seeing around 2.7.
For very short drives (<4 miles) at temps below 20F and no preconditioning, I routinely see sub 2.0 M/kwhr. I attribute that to energy used to make the battery all nice and comfy! Seat heat on and E-heat set to 68.

If I stop the car, go into the store briefly, and make the return home, I get mid to upper 2s.

This likely the scenario where the OP is seeing 1.7.

Do you know the production date for your car? Early models have a lot of module updates needed. Dealers are still trying to figure out how to service the MME, but maybe your dealer is well educated and knows how to update modules. I would ask about that. However, I have not seen anyone else report range issues related to a module update.

Your exterior temperature is not that low so I am surprised you are getting less than 2 kWh for your commute. 240 miles round trip to London must include some fast motorway driving, right? If you keep the speed around 70 mph and accelerate slowly in the city you might make it, but it will be very close. You can expect that highway range in the summer will be around 220 miles if you stay around 70 mph. Really you need to find a convenient place to charge while in London or plan to charge on your way home, especially in the winter. That is just based in my experience so far, and following others in this forum.

I routinely get down to 1.2 to 1.6 leaving our subdivision and getting out on the county roads. This is part of what has lead the GOM to predict 198to 205 miles range at 100% SOC. It’s not indicative of my actual range though.

If it makes you feel any better my 2019 ranger is getting about 13 mile to the gallon on my 6 mile commute when the temps are below zero.... (normally it would be in the 20's per gallon) :)

So if i drive like a normal person then getting "extended range" of around 300 miles per charge is a dream and far from reality. I did see a post about Guinness record set by MME 6.5m/kwh. I guess they were pushing it around. I do allot of town riding, very lottle motorway, loads of school runs, local shops, office, town etc. Getting fast charges installed in office next couple weeks, will charge to full and drive till basically empty and see were i get and plan to do that when the weather is still coldish and again when arou d +15 to see the difference. I do not intend to wear gloves and freeze in a £60k motor just so i can squeeze some more miles oit of it, will just have to live with what it is and charge more often, borrow my colleague Discovery for longer runs if have to?‍♂
Thanks for all your answers, i have learned allot in last couple days.

As others have posted, I think the reason you have such poor efficiency is because you are only driving 2 miles to work. Today I paid attention to my trip efficiency when we went out, and up to around 2 miles my efficiency was very low. But when I reached 5 or 6 miles, I was over 3 mi/kWh, driving softly (because my wife was in the car). So I bet you will get much better efficiency when you drive a little farther.

In the end though, if you are only driving 4-5 miles a day and you can charge at home, efficiency is not really important. Use as much heat as you want and push that go pedal to the floor! Keep your car charged between 70 and 80% and you will only be charging once or twice a week (assuming 5 miles a day, of course).

Owning a BEV is a paradigm shift. As you get used to the differences, hopefully you will really appreciate the benefits. Like never needing another oil change. Or starting your car with the garage door closed. Or never needing to stop for gas (or a charge) ever, unless you need to take a trip out of town. It is so much better is so many ways. Focus on that! ;-)
