Good question! A 2019 Kia Soul + (Plus) has a gas tank capable of holding 14.2 gallons of fuel—fairly large for a car its size, and with good fuel efficiency to boot.
When the 2019 Kia Soul Plus’ 14.2 gallon gas tank is filled to capacity, you’ll get roughly 383 miles out of it before having to stop and refuel. This estimated mileage is based on the combined city and highway miles-per-gallon estimates, which are 355 and 426 respectively.
If you don’t feel like doing the math, that calculates out to about 27 miles-per-gallon—slightly higher than the average of all other cars produced in 2019.
