30 MPG combined is respectable for the 2020 Volvo S90 T8 eAWD Plug-In Hybrid, but that’s not the whole story. This is a luxurious sedan with all-wheel drive and a turbocharged engine with electric motor. Buyers are often seeking a blend of lower fuel costs and premium features, prioritizing less gas without sacrificing comfort, performance, or Scandinavian design.

City and highway performance

The EPA estimates the S90 T8 at 28 MPG in the city and 31 MPG on the highway. These figures reflect a blend of gasoline and electric power usage during typical driving conditions. The city MPG benefits from the electric motor smoothing out stop-and-go driving, while the highway MPG drops slightly due to increased reliance on the gasoline engine at higher speeds. Of particular note: with a fully charged battery, much of your in-town driving can be accomplished with zero gasoline consumption.

Annual fuel cost

The EPA estimates an annual fuel cost of $1,950 for the 2020 Volvo S90 T8 eAWD Plug-In Hybrid. This figure is based on driving 15,000 miles per year, with a certain percentage of those miles driven under electric power, at the national average fuel price. Keep in mind that your actual fuel costs could vary depending on your driving habits, local fuel prices, and how frequently you charge the battery. Drivers who consistently charge their S90 T8 and primarily use it for shorter commutes may find their fuel costs significantly lower than the EPA estimate.

Real-world expectations

Achieving the EPA’s 30 MPG combined rating, or even exceeding it, is realistic in the S90 T8, but it requires adapting your driving style to maximize the benefits of the plug-in hybrid system. Regular charging is important; the more you rely on electric power, the less gasoline you’ll burn. Aggressive acceleration and high-speed driving will deplete the battery faster and force the gasoline engine to work harder. Drivers who mainly use the S90 T8 for long highway trips may see fuel economy closer to a traditional gasoline-powered sedan. Check out S90 MPG across all years to compare.

How it compares

Compared to other luxury sedans with similar technology and performance, the S90 T8 is a good value in terms of fuel efficiency, particularly with its ability to function as a plug-in hybrid. A comparable Mercedes-Benz E450 4MATIC with its gas-only engine achieves around 25 MPG combined. The BMW 530e, another plug-in hybrid competitor, gets around 29 MPG combined. The Lexus ES 300h hybrid manages 44 MPG combined but lacks the Volvo’s plug-in capability and all-wheel drive. The S90 T8 offers efficiency without sacrificing the comforts and features expected in a luxury sedan.

Tips to maximize efficiency

Make charging a routine. Plug in the S90 T8 whenever possible, whether at home, work, or public charging stations. Consistent charging ensures that you maximize electric driving range and minimize gasoline consumption. This is particularly effective for those with short daily commutes.

Employ gentle acceleration and braking techniques. Rapid acceleration and hard braking deplete the battery quicker and increase fuel consumption. Driving smoothly and anticipating traffic flow will allow the regenerative braking system to recapture energy and extend your electric range.

Use the S90 T8’s driving modes wisely. The “Pure” mode prioritizes electric driving, ideal for short trips and city driving. The “Hybrid” mode optimizes the balance between electric and gasoline power for overall efficiency. The “Power” mode prioritizes performance, but it can significantly reduce fuel economy.

Minimize accessories that draw power. Running the air conditioner, heated seats, and other electrical accessories can put a strain on the battery and reduce electric driving range. Use these features judiciously, especially when driving in electric mode.

Keep tire pressure at the manufacturer’s recommended levels. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Regularly check tire pressure and adjust as needed. And consider using low-rolling-resistance tires when it’s time for a replacement.
