The 2022 Volvo S90 B6 AWD gets 26 MPG combined, which places it among its competitors. Many buyers will accept this, as the S90 prioritizes comfort, safety, and Scandinavian design. It’s a luxury sedan, and while good gas mileage is a plus, it’s not the top priority. S90 buyers want a quiet driving experience and a well-made interior more than saving every possible drop of fuel.

City and highway performance

The EPA estimates the S90 B6 AWD achieves 23 MPG in the city and 31 MPG on the highway. The city MPG reflects stop-and-go traffic, where the 2.0-liter four-cylinder engine, with its turbocharging and supercharging, works harder. The highway MPG is better. The S90 has a smooth-shifting 8-speed automatic transmission that settles into a relaxed cruise, and the car’s aerodynamic shape helps it glide efficiently at higher speeds. The EPA numbers are based on careful testing. Your own driving habits will affect your actual MPG.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Volvo S90 B6 AWD 2.0L 4-cyl at $2,250. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual cost will depend on how much you drive and the price of gasoline where you live. Premium fuel is recommended for the S90 B6. This will increase your fuel bill compared to vehicles that use regular gas.

Real-world expectations

The EPA provides a benchmark, but real-world fuel economy varies. Aggressive driving, frequent short trips, and extended idling will reduce efficiency. Smooth acceleration, consistent speeds, and a lighter vehicle help improve fuel economy compared to EPA estimates. Weather and tire pressure also matter. Drivers who get better fuel economy in their S90s tend to drive more carefully.

How it compares

The S90’s 26 MPG combined is similar to some rivals, but different from others. For example, the BMW 530i with its 2.0-liter turbocharged four-cylinder also gets around 27 MPG Combined. The Mercedes-Benz E350, another key competitor, gets about the same MPG. However, more powerful six-cylinder versions of these cars, like the BMW 540i which delivers 25 MPG Combined, usually have lower fuel economy. If you’re considering the S90 B6, compare it to the Lexus ES 350. It often has slightly better real-world MPG thanks to its V6 engine and focus on fuel efficiency. For a broader perspective, review S90 MPG across all years and see how this model year stacks up.

Tips to maximize efficiency

Use the S90’s Eco drive mode. This adjusts throttle response and transmission behavior to emphasize fuel efficiency. The car might feel less responsive, but it can save you gas.

Check your tire pressure regularly. Underinflated tires increase rolling resistance. This reduces your fuel economy. Check the sticker on the driver’s side doorjamb for the right tire pressure.

Avoid accelerating and braking hard. Smooth changes in speed use less fuel than sudden bursts of power. Watch traffic and drive at a steady speed.

Reduce idling. If you’re stopped for more than a minute, turn off the engine. Modern cars restart fast, and idling wastes gas.

Think about limiting your use of all-wheel-drive during good weather. The S90’s AWD system improves traction on slippery surfaces, but it can slightly reduce fuel economy on dry roads. The system only engages when needed, which helps maintain fuel economy. For a broader look at the brand, you can always view all Volvo fuel economy data.
