The EPA-estimated range of a Ford F-150 Lightning XLT SR is 230 miles. Ford had been targeting 230 miles and nailed it.
The EPA-estimated range of a Ford F-150 Lightning XLT ER is 320 miles. Ford had been targeting 300 miles, so that extra 20 miles is a positive accomplishment.

Still, some people look at those number and are, well, underwhelmed.
Of course, take into account that this is a pickup truck, so that means it is big and heavy, which doesn’t do wonders for electric vehicle range.
Ford offers a 5-liter V8 for the F-150.
A 4×4 with the engine returns a combined 19 mpg.
The truck can be specified with gas tank size. The smallest is 23 gallons. The largest is 36 gallons.
A V8 F-150 with the 23-gallon tank has a range of 437 miles.
A V8 F-150 with the 36-gallon tank has a range of 684 miles.
Somehow really makes those Lightning numbers seem, well, underwhelming.
