What makes you think it only had a range of 283 miles. Are you confusing the Guess-o-Meter for actual range?

had 2023 Lariat ER , I know what to expect. this one has much worse range performance with same driving. i'm closer to standard range not to ER.

 

[jftexan]

That is more efficient than the EPA highway rating, which would yield a theoretical ~249 miles @ 1.9 mi/kWh @ 100%-131 kWh battery on 20 in. wheels. I don't know which wheels are on the Flash.

The EPA test is the problem. Click on test details tab.

Detailed Test Information

EPA tests vehicles by running them through a series of driving routines, or schedules, that specify vehicle speed for each point in time during the laboratory tests.

I read the detailed link, but how do they get to 320miles combined when they are only showing 1.9 to 2.3 which is nowhere near 320 on a 131kwh battery?

I have SR and max range is 220 within EPA estimate of 2.2 miles per kilowatt hour.

You should be asking why your miles per kilowatt hour is lower than the lariat. Wind, temp, and traffic can all come into play. Is it something different about the flash that’s giving you lower mi/kwh. Are the tires more aggressive than your lariat? Did the window sticker have different range estimates? The XLTs were different from the Lariats back in 2023.

Strange, my Flash charged to 100% is always between 320-340 miles. My last charge to 90% got to 299 miles.

To clarify, you are seeing this range practically (city or highway) and the truck never estimates this high right? 100% charge for me is typically estimating 275-280. I have to drive very conservatively at about 2.5-2.6kwh to get close to the 320.

According to the window sticker EPA calc, they says 48kwh per 100 miles. So that would suggest it has a 150kwh battery when its only 132kwh (per specs).

PS - I have the 2024 Flash with 20" wheels, not sure if anyone has seen vastly diff results between smaller size wheels.

looks like we are having the same truck trim. I drove very moderate and I have got around 250. 10% less than GOM when 100% charge.{283 miles}
what is your gom range when fully charged?

 

[Henry Ford]

GOM range is useless. It has no bearing on vehicle health. Zero. Any conversation about vehicle health that includes GOM is a waste of time.

 

[ChasingCoral]

I drove very moderate and I have got around 250.

Please provide some details. What do you mean by "very moderate"?

[/QUOTEt
60 mph on highway. city mainly driving , no rapid acceleration etc...

 

[Voltz]

tks, definitely have issue with the truck. looks like I got standard range and not ER.

Nope.
How many miles a day do you normally drive?

 

[Leaf-clarity]

You stated that you averaged 2 miles per kilowatt hour for Vegas to la. From that result the GOM will give you 130 kWh x 2 mi/kwh = 260 ish miles on your next trip. Which it did.

Did your Lariat give you better average on the same trip?

Also the GOM was much more glitchy in the beginning. I personally think it does a decent job guessing what you should get based on your recent trips. In the end it’s easier to do quick math. 130 times your mi/kwh average. If that math does add up the I would guess something might be wrong.

 

[VAF84]

Seems normal to me for ER. However I’ve always had a sneaking suspicion that there may be some differences in efficiencies between trucks. I get we have differences in driving styles, but the ranges have been pretty huge between what different people are getting in range. I’ve heard of numbers on here that I’ve never come close to hitting. I’m still willing to accept that it’s just my use case and driving style, but the little conspiracy theorist in me questions it!

purchased my second F150 lightning extended range. my first one was a Lariat 2023 . no range issues. after 100% charging , got 320-330 range after eco driving. the actual range was a bit less, around 10%.
my new 2024 flash trim is not even close. with all super eco driving factors i'm getting 270-280 miles of range after 100% charging and actual range is also about 10% less - about 240 miles. again no towing, no payload just 2 people with very moderate driving combined city and highways. any help before taking to the dealer.r

I’m not saying that your mileage is wrong but I find that if you change your battery to 80 or 90 percent and then use your cruise control most of the time you get many more miles (I get 285 to 300 )your cruise control works even at 35 mph.
The charging from 85 to 90 % to 100% uses as much time and ware on your battery as all all the others charging combined.
Try it , your truck will be better off and you won’t need as much charger time and it will cost you less .

Please try it anyway.

I bought a '22 Lariat ER mannequin that sat in a showroom for 6 months. Not sure how many times it was charged over that period. It had a few hundred miles. The first 2-3 times I charged it to 100% the GOM would be @ 260 miles range. Not sure what changed. But, it was like the vehicle had a memory. I think your "reset" comment is right on. Typically my GOM returns @ 360 mile with my truck at 15k miles. It is using my "driving habits" to come up to that number. As for mile/kwh it is simple math to get to 320 miles range you have to do average 2.44miles/kwh. Drive over @68 mph you will never get it. Head wind you will never get it on the highway. Run the heat on the highway never get it. Drive 50-55mph you can exceed it all day!

Reset is key and easy to do.

Thanks, I'll try "reset". Half of my mileage was freeway LA to Vegas in hot days . remaining city also very hot climate . noticed that around 30% went for" exterrior temprature, accessories and AC. is that normal?

HI @mosh, Did you ever figure this out? I have the same issue with my 2024 Flash. It has never been higher than 270 miles at 100%. The previous 2023 ER Lariat consistently reported 320 miles at 100%.

If you are relying on the Guess-o-Meter for these differences, it could be as much a matter of your recent driving style as anything else.
