The 2023 Volvo S90 B6 AWD gets 26 MPG combined, which won’t break any fuel-efficiency records. However, it’s a reasonable number for a large, luxurious sedan with all-wheel drive. This reflects the S90’s purpose: a comfortable, stylish, and safe car for long trips rather than a strict economy car. Buyers likely value power and confident handling more than minimizing fuel consumption.

City and highway performance

The EPA estimates the S90 B6 AWD gets 23 MPG in the city and 32 MPG on the highway. The city MPG reflects urban driving’s frequent stops, where the engine’s start-stop system and the car’s weight affect fuel use. But, on the open road, the S90’s smooth 8-speed automatic transmission and efficient 2.0L turbocharged and supercharged engine allow it to achieve a solid highway MPG. This is where the car performs well, offering comfortable and reasonably economical long-distance travel. Drivers can see all S90 MPG across all years to compare the 2023 model.

Annual fuel cost

The EPA estimates the 2023 Volvo S90 B6 AWD’s annual fuel cost at $2,250. This is based on 15,000 miles per year, a mix of city and highway driving, and average national fuel prices. This is a helpful benchmark for budgeting, but individual driving habits and fuel prices can change this number. Premium fuel is recommended for the best performance and long life, affecting the total cost. Check all Volvo fuel economy data to compare ratings across Volvo’s lineup.

Real-world expectations

While the EPA provides a standard estimate, real-world MPG often differs. Quick acceleration, frequent short trips in cold weather, and exceeding speed limits will all lower fuel economy. Conversely, gentle driving, regular maintenance, and prioritizing highway miles can improve on the EPA estimates. Expect to see figures in the low to mid-20s during typical city driving and near, or even above, 32 MPG on longer highway trips at consistent speeds.

How it compares

Among large luxury sedans with all-wheel drive, the S90’s fuel economy is competitive, but not the best. The BMW 530i xDrive, for example, gets 27 MPG combined, a slight advantage. The Mercedes-Benz E 350 4MATIC gets a similar 25 MPG combined. Though those vehicles may have better MPG, the Volvo S90 has other qualities, like styling and interior luxury, that might be more important to buyers. Ultimately, the S90 buyer isn’t focused solely on fuel savings; they value the overall experience, including safety, comfort, and Scandinavian design.

Tips to maximize efficiency

The S90’s start-stop system saves fuel in city driving, despite being disruptive to some drivers. Using it will help save gas, especially in areas with many stops.

Check tire pressure regularly. Underinflated tires increase rolling resistance, making the engine work harder and burn more fuel. Use the pressure listed on the driver’s side door jamb.

Avoid idling. If stopped for over a minute, turn off the engine. Modern cars restart quickly, and idling wastes fuel.

Gentle acceleration and consistent speeds help. Avoid sudden acceleration and keep a steady pace on the highway. The S90’s turbocharged engine has plenty of torque, so pushing its limits is unnecessary.

Reduce weight. Remove unneeded trunk items. Added weight makes the engine work harder, lowering fuel economy. Golf clubs, sporting equipment, or books can affect fuel efficiency.
