Do you think Ford and the other companies you mentioned just pick a number that they think will sound good and publish it on their labels? There's a defined test process that each manufacturer uses to arrive at those numbers, shown in the link below.
The biggest reason that new EV drivers are surprised about the impact of cold weather is that they are totally clueless about the impact of cold weather on a gas vehicle. The majority don't know that winter gas exists, or that cold weather drops their mpg. https://www.energy.gov/energysaver/...d weather and winter driving,to 4-mile) trips.
You aren't understanding this at all. You can figure your range without driving to zero... Display says a range at say 80%. Divide by 0.8 and you have the useless range. Now, drive your drive. Write down the range, and divide by that SOC. Now you see the impact of reality.
Range is variable, and much under the control of the driver. Motor Trend prepared an eye-opening graph of their longterm test Lightning’s range vs. highway speed:
This is pretty much right where I'm at in Washington State in my Flash. Unless you are in the south, it's hard to do better this time of year unless you are just creeping around a flat city.Imputed 100% range [243/.84=289.3 miles range @ 100%]

We have a few old threads where experts members shared detailed discussion about how the energy management system doesn't always show the rated capacity in kWh, factors such as temperature and cell / module state of health play factor in these values.
That may be true, it can measure the consumption pretty accurately. What he was saying is that the actual capacity of the battery is dependent upon a variety of things, basically that it may be "131kwh" but only when certain outside conditions are met. I mean, we don't expect a battery at 10f to have the same capacity as at 70f.
The EPA rating allows manufacturers to de-rate their range figures to better reflect reality, and companies like Mercedes do this honestly, but companies like Ford and Tesla are choosing to intentionally mislead their customers with these fantasy range figures. All this will do is disappoint potential customers like OP who can end up buying a car that won't work for them.
You mean the window sticker rating for someone living in Texas should reflect mileage ratings for the North Slope of Alaska?
Anyone who makes a vehicle purchase decision based solely on what the manufacturer says and doesn’t do their own research deserves to be disappointed. There’s plenty of hands-on reviews and 3-party data that’s easily found and accessed.
Then why not base range on only 70% of the battery pack? Operating between 20% and 90% is reality for most customers. And with worst-case range scenarios for ER trucks about 180mi (85mph highway, even less for towing or extreme cold!) and best case over 400mi (nothing but low speed stop-and-go in good weather), isn’t it better to tell custowners a typical “average” range based on most people’s driving requirements? People have to learn that EV range isn’t up to the vehicle, as much as it is up to the driver!
