Mild-Hybrid Volvo XC90 MPG Ratings

The mild-hybrid 2026 Volvo XC90 has two powertrain options, and the Volvo XC90 fuel economy ratings, as determined by the Environmental Protection Agency (EPA), are excellent. The first is the B5 AWD, which pairs a turbocharged 2.0-liter four-cylinder engine with a battery-and-motor system to produce 247 horsepower and 266 pound-feet of torque. As discussed, it achieves an EPA-estimated 22/27/24 MPG (City/Highway/Combined).¹

The available Volvo XC90 B6 AWD powertrain also combines a turbocharged 2.0-liter four-cylinder engine with a battery-and-motor system, but it adds a supercharger and offers more power: 295 horsepower and 310 pound-feet of torque. It earns an EPA-estimated 20/26/23 MPG (City/Highway/Combined).³

Volvo XC90 Plug-In Hybrid MPG Ratings

The other Volvo XC90 MPG ratings are now known as the "Volvo XC90 Plug-In Hybrid MPG ratings." While they used to be called the "Volvo XC90 Recharge MPG specs," this variant was renamed in 2025 and continues to be called the "Volvo XC90 Plug-In Hybrid" for 2026.

Regardless of name changes, this is the most efficient model in the Volvo XC90 SUV lineup. It comes with a standard and exclusive T8 AWD PHEV powertrain that makes 455 horsepower and an astonishing 523 pound-feet of torque, earning a rating of 27 MPG (Combined) for the gasoline engine.⁴ Even though this Volvo XC90 hybrid MPG rating combines with 208 more horsepower than the B5 AWD option, it is still higher than that mild-hybrid powertrain. As we'll see below, the vehicle scores much higher numbers when you leverage its electric abilities.

Volvo XC90 All-Electric Range

The Volvo XC90 Plug-In Hybrid has the ability to operate solely on electric power for a while, leaving the gas engine on standby. When you're driving in the all-electric Pure Mode, you'll have an EPA-estimated range of up to 32 miles on a single charge.⁵ For many people, this is enough to complete one day's commute or run errands around town before needing to use gasoline or recharge the battery.

To put the relative efficiency of this electric motor into perspective, it received an EPA-estimated miles-per-gallon equivalent (MPGe) rating instead of a regular MPG rating: the Volvo XC90 PHEV delivers an EPA-estimated 58 MPGe (Combined)⁵ when you use it in its hybrid mode (which will be common for many drivers).

As for the mild-hybrid Volvo XC90, it does not offer all-electric driving, but focuses on using its hybrid power to enhance the gas engine's efficiency. Its respectable MPG ratings can go the distance, however. If you take advantage of our new Volvo vehicle specials, you can save on your new Volvo XC90 itself, in addition to all the gas savings you'll accrue in the long run.

Volvo XC90 Gas Tank Size

Both the mild-hybrid and plug-in hybrid variants of the Volvo XC90 SUV can hold up to 18.8 gallons of fuel. Thanks to these models' efficient powertrains and impressive fuel economy ratings, you might be surprised just how far those 18-plus gallons can take you. This is one of the many reasons why the Volvo XC90 is considered a gold standard for road trip vehicles – your SUV is equipped to travel far and eliminate the need for frequent gas station stops.

For further research, you can compare Volvo XC90 hybrid MPG to the new Volvo XC40 mileage. This smaller model is also a mild-hybrid SUV with two rows of seating.

Frequently Asked Questions

What factors can affect the fuel efficiency of the 2026 Volvo XC90?

The 2026 Volvo XC90 MPG rating is affected by a variety of factors: your driving habits, local climate, vehicle specifications (i.e., wheel size), how well you keep up with regular maintenance appointments, and more. Our dealership recommends faithfully following your owner's manual's guidelines for oil changes, coolant flushes, and overall tune-ups to make sure your automobile is operating at its fullest potential for performance and fuel efficiency.

What other factors affect the fuel efficiency of the Volvo XC90?

Other factors that can affect the fuel efficiency of the Volvo XC90 SUV lineup include driving conditions, such as stop-and-go traffic, which can reduce mileage. Terrain also plays a role – hilly or uneven roads can demand more engine power, which reduces your overall fuel efficiency. Improper tire pressure, excess vehicle weight, and towing can also negatively affect your fuel efficiency.

How does cold weather affect the MPG of the Volvo XC90?

Cold weather can place more demands on your car's battery and can make the engine's warm-up time longer, which in turn will consume fuel without adding more distance to your drive. The reduction in fuel efficiency will depend on several factors, but temperature, terrain, and driving habits are always high up on the list; our knowledgeable Volvo specialists can help you understand this better.
