How far can a Cherokee go on a tank?
Simple math with the sheet figures: 13.7 gallons at the 2026 Cherokee's 37 mpg combined rating works out to about 507 miles. At the 2027 Trailhawk's 31 mpg combined rating it is about 425 miles.
That is our arithmetic, not a Jeep or EPA range figure. Your miles per tank will vary with speed, temperature, load and how you drive.
