29 MPG combined isn’t going to win any hypermiling awards, but it’s a respectable figure for the 2022 Volvo S90 T8 AWD Recharge Extended Range, considering it’s a luxurious, spacious sedan with a potent plug-in hybrid powertrain and standard all-wheel drive. This isn’t a vehicle primarily chosen for its fuel-sipping abilities. Buyers prioritize comfort, safety, style, and lower fuel costs, accepting the fuel economy trade-off as part of the package.

City and highway performance

The EPA numbers break down to 28 MPG in the city and 31 MPG on the highway. These figures highlight the S90 T8’s strength. The plug-in hybrid system allows for significant electric-only driving in urban environments, bumping the city MPG close to, and sometimes even exceeding, the highway MPG. On longer highway journeys, the gasoline engine takes over as the primary power source, resulting in a more typical fuel consumption pattern. This flexibility is key to the S90 T8’s appeal, offering the potential for emissions-free commutes and respectable long-distance fuel efficiency.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Volvo S90 T8 AWD Recharge Extended Range at exactly $2,000. This figure is based on driving 15,000 miles per year, with a mixture of city and highway driving, and using the national average fuel prices at the time of calculation. Individual fuel costs will vary depending on local fuel prices, driving habits, and the percentage of time spent driving on electric power only. Those who diligently charge the battery and primarily use the car for short trips could see significantly lower fuel expenses.

Real-world expectations

While the EPA figures provide a useful baseline, real-world fuel economy can vary considerably. Owners who maximize the use of the electric motor and regularly plug in the car can see average fuel economy far exceeding the EPA combined rating. On the other hand, those who rarely charge the battery and primarily rely on the gasoline engine will likely experience fuel consumption closer to a standard gasoline-powered sedan. Driving style, terrain, and weather conditions also play a significant role in affecting the actual MPG achieved. Diligent charging habits are the key to extracting maximum fuel economy from this particular model.

How it compares

Compared to its competitors, the S90 T8’s fuel economy strikes a balance. The BMW 530e, another plug-in hybrid luxury sedan, achieves a combined 25 MPG. The Mercedes-Benz E350, with its gasoline-only engine, manages around 26 MPG combined. The Lexus ES 300h hybrid, a non-plug-in hybrid, boasts an impressive 44 MPG combined, but sacrifices the S90’s power and plug-in capability. The Audi A6 55 TFSI e quattro achieves 27 MPG combined while offering a similar plug-in hybrid experience. These comparisons highlight that the S90 T8 prioritizes performance and luxury alongside some electric capability, whereas some of its competitors focus more on outright fuel efficiency. Those seeking better numbers should view S90 MPG across all years to see if another model year suits their needs better. You can also see all Volvo fuel economy data on this site.

Tips to maximize efficiency

Take full advantage of the “Pure” driving mode. This mode prioritizes electric power, allowing you to drive on battery alone for as long as possible, drastically reducing fuel consumption. Aggressive acceleration and high speeds quickly deplete the battery and force the gasoline engine to engage, so a gentle driving style is key to maximizing electric range.

Regularly charge the battery. The S90 T8’s plug-in hybrid system is most effective when the battery is fully charged. Make it a habit to plug in whenever the opportunity arises, whether at home, at work, or at public charging stations. Aim for Level 2 charging when possible, as the 240V charging rate will replenish the battery far faster than a standard 120V outlet.

Plan your routes strategically. If you know you’ll be driving in stop-and-go traffic, prioritize electric-only driving to minimize fuel consumption. If you’re planning a long highway drive, consider using the “Hybrid” mode, which intelligently blends electric and gasoline power to optimize fuel efficiency for the entire journey.

Optimize tire pressure. Properly inflated tires reduce rolling resistance, improving fuel economy. Check your tire pressure regularly and inflate them to the recommended levels, which can be found on the driver’s side doorjamb or in the owner’s manual. Consider using low rolling resistance tires when it’s time for replacement.

Minimize unnecessary weight. Carrying unnecessary weight in your car reduces fuel economy. Remove any items you don’t need, such as golf clubs, sports equipment, or extra luggage. A lighter car requires less energy to move, resulting in better MPG.
