EPA numbers wrong or battery much larger

[Texas Dan]

I just looked at the performance numbers for the F150L that were just posted on the EPA website, https://www.fueleconomy.gov/feg/Find.do?action=sbs&id=45317. The website indicates an electric consumption rate of 48 kWh/100 miles. With the listed range of 320 miles, then the available battery capacity would have to be 154 kWh (48*320/100), which is much higher than the 131 kWh advertised by Ford.

I thought perhaps I was performing the calculation incorrectly so I checked the values of the Audi eTron (has about the same energy performance). The eTron has a listed energy consumption of 46 kWh/100 miles and has a listed range 208 miles, which calculates to a battery capacity of 96 kWh. The advertised battery capacity for the eTron is 95 kWh so the calculation methodology appears correct.

So what’s happen here? Are the EPA numbers incorrect? Is Ford lying to us about the battery capacity?

I believe that EPA consumption numbers are calculated “at the wall” so they account for charging losses. Although that doesn’t explain the eTron.

There's another post in here about this and I'm too lazy to find it right now. Basically, the EPA numbers account for how much energy you would take from the outlet and accounts for energy losses in the transfer. It does not measure the actual amount of juice you're putting into the battery.
(or is it the other way around??)

Also remember its not a 1:1 comparison, 1 gallon of gas is equal to 33.7 KwH of electricity.

Using Miles per KwH is a much better metric to use...and if you calculate out 320mi/131 KwH you get 2.4KwH which is right around the numbers for Rivian and other EVs this size.

The numbers seem to be better than I would have guessed.
Thought they would have been slightly less than Rivian.
Usually the OEM does the EPA tests and submits the results so your mileage can vary.
