How big is the gas tank on a Volvo XC90?

Volvo’s three-row midsize luxury SUV has a large fuel tank to power the XC90 on the road. But depending on the trim level and powertrain, the exact size of your gas tank will range between 18.5 gallons and 18.8 gallons
First, you’ll have a choice between four trim levels: Momentum, Inscription Expression, Inscription, and R-Design
Then, you have your choice between three engine options for the XC90:
  • 2.0-liter turbocharged inline-4 (T5)
  • 2.0-liter turbocharged/supercharged inline-4 (T6)
  • 2.0-liter turbocharged/supercharged plug-in hybrid inline-4 (PHEV)
Let’s say you go base all the way and choose the Momentum trim level with a T5 engine, then your gas tank capacity will be 18.8 gallons. Even with the third-level Inscription and a T6 engine, you’ll get the same result! But if you opt for the PHEV (that’s available on all trim levels except the base Monumentum), then your gas tank shrinks ever so slightly to 18.5 gallons

How to check your Volvo XC90’s gas tank size

Want to double-check to make sure you have the right gas tank size? Here are a few ways.

Measure the gas tank

If you want to measure your gas tank yourself, then bust out your handy dandy measuring tape and a calculator first! Then you’ll want to multiply the width, length, and height of the tank and divide that number by 231, or the number of cubic inches in a gallon. 

Check your owner’s manual

Still have your owner’s manual around? Gas tank information should be included! Scan the table of contents or index for terms like “fuel tank capacity” or “gas tank capacity” and you should get your answer in no time. 

Drive till empty, then fill it up

If the previous two solutions don’t work for you, then you can always find out your XC90’s fuel tank size by just driving around until you nearly hit “E” and immediately refilling it! It might sound crazy and you won’t get a precise measurement, but you will get a ballpark figure with this daring method. Just don’t drive on empty for too long, though!

How to save on fuel costs in a Volvo XC90

With a base T5 engine and all-wheel drive, the 2022 Volvo XC90 receives an estimated EPA rating of 20/28 mpg for city/highway. But with a plug-in hybrid model, the XC90 is rated at 55 MPGe and 27 mpg with gas only
Even with a fuel-efficient midsize luxury SUV like the XC90, there are still plenty of ways to save more at the pump with the following tips:
  • Regular maintenance schedule. Keeping up with a proper maintenance schedule is an easy way to also maintain your fuel consumption. 
  • Drive with ease. Go easy on your gas pedal! Accelerating too harshly will cause your fuel economy to plummet. 
  • Avoid idling, especially in cold weather. Friends don’t let friends idle around! Instead of letting your XC90 warm up in the driveway, try gently driving it around to warm it up as an alternative to idling.
