27 MPG combined is a perfectly acceptable fuel economy figure for the 2017 Volvo S90 FWD 2.0L 4-cylinder, largely because this car’s appeal goes beyond efficiency. It is a stylish, comfortable, and understated luxury sedan aimed at buyers who prioritize Scandinavian design and a premium driving experience over fuel savings. The S90 buyer wants a distinctive alternative to the more common German offerings and is willing to accept middle-of-the-road fuel economy to get it.

City and highway performance

The EPA estimates 23 MPG in the city and 34 MPG on the highway for this S90 configuration. The city figure reflects the stop-and-go nature of urban driving. The 2.0L engine works harder to overcome inertia at each intersection. The highway number, on the other hand, is where this car excels. With its eight-speed automatic transmission settling into a relaxed overdrive and the engine breathing easily at cruising speeds, the S90 can deliver genuinely impressive long-distance mileage. This makes it a surprisingly competent road-trip machine, especially with its comfort and refinement.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,150 for the 2017 Volvo S90 FWD 2.0L 4-cylinder. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs may vary depending on your driving habits, the type of fuel you use, and the gas prices in your area. If you primarily drive in the city, or if fuel prices are higher than average in your region, expect to spend more than $2,150 per year fueling your S90. If you do mainly highway driving and fuel prices are relatively low, you might spend less.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy can vary significantly depending on driving style, traffic conditions, and even the weather. Aggressive acceleration, frequent braking, and extended idling will all negatively impact your MPG. Cold weather can also reduce fuel economy as the engine takes longer to reach its optimal operating temperature.

The S90’s trip computer can provide a more accurate reflection of your actual fuel consumption. You can monitor your MPG and adjust your driving habits accordingly. Checking S90 MPG across all years in owner forums can also reveal more realistic MPG averages from other drivers.

How it compares

Compared to its rivals, the 2017 Volvo S90’s fuel economy is similar. The BMW 530i, for example, achieves a similar 27 MPG combined with its 2.0L Turbo engine, while the Mercedes-Benz E300 also hovers around the same figure. The Audi A6 2.0T, another competitor, posts a slightly better 28 MPG combined. These numbers matter, but the S90 buyer isn’t solely focused on MPG. They also value the car’s unique design, comfortable interior, and emphasis on safety. For buyers more concerned with fuel economy, the Lexus ES 300h hybrid offers significantly better MPG, but at the expense of driving dynamics and luxury appointments.

Tips to maximize efficiency

The 2017 S90 isn’t a fuel-sipping hybrid, but some steps can improve its fuel economy. Smooth and steady acceleration is key. Avoid sudden bursts of speed and try to maintain a consistent pace, especially on the highway. The S90’s available “Eco” mode can also help by optimizing the engine and transmission settings for maximum efficiency.

Proper tire inflation is another often-overlooked factor that can impact fuel economy. Check your tires regularly and ensure they are inflated to the recommended pressure, typically found on a sticker inside the driver’s side door jamb. Underinflated tires increase rolling resistance. As a result, the engine works harder and burns more fuel.

Reduce unnecessary weight in the vehicle. Extra cargo in the trunk or backseat adds load to the engine, decreasing fuel efficiency. Remove any items you don’t need to carry regularly. The S90 sedan’s trunk is already quite spacious, so keeping it clutter-free is relatively easy.

Minimize idling. Avoid prolonged idling whenever possible, especially in cold weather. Modern engines warm up relatively quickly while driving, and idling wastes fuel without getting you anywhere. If you’re going to be stopped for more than a minute or two, it’s generally better to turn off the engine.

Consider using cruise control on the highway. This helps maintain a consistent speed, prevents unnecessary acceleration and deceleration, and can improve fuel economy. While the S90 has adaptive cruise control, use it on the highway without traffic to help achieve the best possible MPG.
