The Kia Forte can go an average of 32 miles on empty, but this depends on a few other factors. One of the major determinants of how far you can go is where you’re driving. Generally speaking, you can go farther on the interstate than you would be able to in the city or on hilly or mountainous terrain.
Another thing that limits how far you can go is your Forte’s engine. Engines with a smaller displacement can often take you a bit farther than one of the larger engines in the Forte lineup— but it’s likely only a mile or two difference.
