22 MPG combined might make some people wonder, but it’s a calculated trade-off for those who buy the 2021 Volvo XC90 AWD with its 2.0L 4-cylinder engine. People don’t buy this vehicle only to maximize fuel efficiency. They buy it for its Scandinavian design, strong safety reputation, and ability to comfortably carry a family and their gear in any weather. The all-wheel-drive system and the heavy weight of a three-row luxury SUV affect mileage, but XC90 buyers are usually willing to accept that.

City and highway performance

The EPA estimates for the 2021 Volvo XC90 AWD 2.0L 4-cylinder are 19 MPG in the city and 28 MPG on the highway. The city figure shows the effect of stop-and-go driving, where the engine’s stop/start system and the vehicle’s weight matter. The highway figure is better because the turbocharged and supercharged engine can run more efficiently at steady speeds. Don’t expect to always get 28 MPG if you often pass other cars aggressively or drive into strong winds, but it’s possible in normal highway driving.

Annual fuel cost

The EPA says the annual fuel cost for the 2021 Volvo XC90 AWD 2.0L 4-cylinder is about $2,650. This is based on driving 15,000 miles per year and using average national fuel prices. Your actual fuel costs will change depending on how you drive, the fuel you buy, and local prices. If you mostly drive short distances in the city, you’ll probably spend more than $2,650. If you drive mostly on the highway, you might spend less.

Real-world expectations

EPA numbers are a standard guide, but real-world fuel economy is often different. Some 2021 XC90 AWD 2.0L owners say they get slightly better mileage than the EPA estimates on long trips. Others get less in mostly city driving. Tire pressure, vehicle load, and driving style all have a large impact. If you accelerate quickly or often tow with the XC90, you’ll likely see lower MPG numbers. Check XC90 MPG across all years to see how this model compares with previous versions.

How it compares

The 2021 Volvo XC90 AWD 2.0L 4-cylinder competes with other SUVs. For example, the Acura MDX SH-AWD gets a combined 21 MPG with its V6 engine. The BMW X5 xDrive40i, with its inline-six, gets a slightly better 23 MPG combined. Even the Mercedes-Benz GLE 350 4MATIC, with a similar turbocharged four-cylinder and all-wheel drive, offers a comparable 22 MPG combined. These differences can add up over the car’s life. The XC90’s buyer, however, often values Volvo’s unique design, safety features, and the optional plug-in hybrid version (Recharge) for better gas mileage. Before you buy, check all Volvo fuel economy data to compare models and trims.

Tips to maximize efficiency

Use the XC90’s Eco drive mode. This adjusts how the accelerator responds and when the transmission shifts to save fuel. It might make acceleration a little slower, but it can improve MPG, especially in city driving.

Check and maintain your tire pressure regularly. Underinflated tires increase rolling resistance, which makes the engine work harder and use more fuel. The sticker on the driver’s side doorjamb shows the recommended tire pressure for your XC90.

Reduce extra weight. Extra cargo in the car adds weight, which reduces fuel economy. Remove anything you don’t need, especially heavy things that can really hurt MPG.

Drive smoothly and consistently. Avoid accelerating hard and braking hard, because these use more fuel. Watch the traffic and keep a steady speed when you can. Using cruise control on the highway can also improve fuel efficiency.

Schedule regular maintenance. Keeping your XC90 maintained helps the engine run efficiently. This includes changing the oil and air filters as the manufacturer suggests. A well-maintained engine uses less fuel.
