My brand new AWD Extended Range is only showing a projected range of 220 miles at 100% charge after a reset of the driving history. I realize that cold weather affects the range, but it's in the sixties today.

Should I be concerned?

Picked up mine a week ago, 229 miles 100 percent, based on my current miles/kWh I could be closer to 290 with round town as I am getting a lot of Regeneration

No. Ours has varied from 200-275 miles since we took delivery on 10/30/21. 3200 miles so far. The 200 mile estimates came last week with daytime highs in the 30s and 40s. This week has been 50s-70s and estimate is now 245-250 again.

Our lifetime efficiency avg. of 3.0 miles/kWh indicates 264 mile range. And we like to accelerate briskly often.

I would be very concerned. This has been quite a problem lately. I can’t find the post but just search “wrong battery” and make sure you’re not affected!

I am sensing large amounts of sarcasm particles eminanting from your post…

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 EPA 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.

15k miles in.

About 315+ miles in summer at 100, and about 200 in winter (Georgia, around 40-50 F mainly).

Important things:
  • Make sure your tires are inflated to the right PSI. This has a noticeable effect on range.
  • Use heated seats/steering wheel to warm yourself up
  • If you have to use temp, warm up the cabin while plugged in via departure times (this will also warm the battery to its comfortable range)
  • Try not to accelerate too quickly (stop lights/passing cars, we all do it)
  • Use Break Coach especially around town to get used to the stopping distance for more regen
  • Don't use the Guess O' Meter (GOM). Use the mi/kWh for a much more accurate range

It's well posted in the forum that temp drops the range. I hate it as much as the next guy that they don't advertise it, but they don't have to and its up to a consumer to do their research.

Never use Break Coach!

Is that a new winter record? Did we just go three days without this question coming up?

Is there a way to lookup lifetime efficiency, or should I just be very careful not to reset one of the two trip meters?
