How big is the gas tank on a 2021 Kia Sorento?

Even though it is available in different trim levels and engine sizes, the 2021 Kia Sorento’s gas tank will only ever hold 17.7-gallons, or approximately 67 liters, of fuel.
To put things into perspective, this means that regardless of whether you have the S, SX, SX Prestige, EX, or LX trim on your 2021 Kia Sorento, its gas tank will still hold 17.7-gallons of gas. When the tank is completely full, you should be able to travel roughly 433 to 469 miles before needing to stop to refuel.

How to check your 2021 Kia Sorento’s gas tank size

Of course, there are a few ways you can determine the size of the gas tank in your 2021 Kia Sorento for yourself—we’ve outlined three of them below:

Measure the gas tank

You can determine the volume of your gas tank on your own using a calculator and measuring tape. Simply multiply the length, height, and width of the tank to determine its dimensions. You can then calculate the size of your Sorento's gas tank by dividing your result by 231 (or the number of cubic inches in a gallon).

Check your owner’s manual

You could also simply consult your owner's manual, in which you should be able to find an exact measurement of your gas tank size by searching for "fuel tank capacity" or a phrase that sounds similar.

Drive till empty, then fill it up

If you're willing to take a chance and don't have access to an owner's manual or a measuring tape, you can determine the size of your 2021 Kia Sorento's gas tank by driving it until the fuel gauge reads "E," then filling it back up. Using this method probably won’t give you an exact measurement of the size of your gas tank, but it will give you a general idea.
Just be careful not to drive for too long on an empty tank!

How to save on fuel costs in a 2021 Kia Sorento

When we take into account different drive types (e.g. AWD, 2WD) and engine sizes, the 2021 Kia Sorento gets between 24.5 and 26.5 MPG combined city/highway.
Now, this isn't bad compared to other midsize SUVs from the same model year, but it could definitely be better. Fortunately, there are a few simple driving habits you can adopt to save gas and cut your fuel expenses, some of which are listed below:
  • Follow a routine maintenance schedule: Allowing system wear and tear to accumulate in your Kia Sorento could reduce fuel efficiency and result in expensive repairs.
  • Maintain consistent speeds: You may use more fuel than necessary if you frequently change your speed, so try to keep your speed constant whenever you can.
  • Drive carefully: Driving the speed limit, easing up on the gas pedal, and braking gradually are all tried-and-true methods of improving your fuel economy.
