26 MPG combined is an acceptable figure for the 2019 Volvo S90 AWD 2.0L. Acceptable, but not outstanding. This car isn’t a sports sedan promising blistering performance, nor is it a hybrid focused solely on less gas. The S90 is a comfortable, stylish, and safe luxury sedan with all-weather capability, and its fuel consumption reflects that mix of priorities. Buyers in this segment value aesthetics, interior refinement, and advanced safety features, often placing fuel economy slightly lower on their list than pure performance or rock-bottom running costs.

City and highway performance

The EPA estimates for the 2019 S90 AWD break down to 22 MPG in the city and 31 MPG on the highway. This split highlights the impact of stop-and-go traffic on the turbocharged and supercharged 2.0-liter four-cylinder engine. The city figure, while not class-leading, is adequate for a car of this size and weight. The highway number of 31 MPG is more impressive and reflects the engine’s ability to cruise efficiently at steady speeds, aided by the smooth-shifting eight-speed automatic transmission. Owners find the highway MPG particularly appealing for longer commutes or road trips, where the S90’s comfort shines. This powertrain is designed for smooth, predictable power delivery rather than outright acceleration, influencing its economy during varied driving scenarios.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Volvo S90 AWD 2.0L at exactly $2,250 per year. This figure is based on driving 15,000 miles annually, with a mix of city and highway driving, and using the national average fuel price. Keep in mind, this is just an estimate. Individual fuel costs can vary significantly depending on driving habits, local fuel prices, and the actual percentage of city versus highway miles driven throughout the year. A driver logging primarily highway miles will likely see a lower annual fuel cost than someone stuck in urban gridlock. It provides a useful benchmark for comparing running costs with other vehicles in its class, and should serve as a good annual estimate.

Real-world expectations

While the EPA provides a standardized testing procedure, the numbers don’t always perfectly translate to the real world. Drivers report seeing fuel economy figures close to the EPA estimates in mixed driving conditions. However, aggressive driving, frequent short trips, and prolonged idling can all negatively impact fuel consumption. Those who prioritize smooth acceleration, maintain a steady speed, and minimize unnecessary idling are more likely to achieve or even exceed the EPA’s figures. The all-wheel-drive system, while beneficial in inclement weather, also adds a small amount of weight and driveline friction, which can slightly reduce fuel economy compared to a front-wheel-drive variant. Drivers should use the EPA estimates as a guideline but be prepared for some variation based on their individual driving patterns.

How it compares

The 2019 S90 AWD competes in a crowded segment of luxury sedans. The BMW 530i xDrive, with its turbocharged 2.0-liter engine and all-wheel drive, achieves a slightly better 27 MPG combined. The Mercedes-Benz E300 4MATIC, similarly powered by a 2.0-liter turbo, also posts a 24 MPG combined rating. The Acura TLX SH-AWD, with its V6 engine, falls a bit lower, at around 24 MPG combined. For buyers considering S90 MPG across all years, the S90’s fuel economy is about average compared to these competitors. Ultimately, the choice often comes down to other factors such as styling, features, and overall driving experience. Potential buyers should compare all Volvo fuel economy data across the Volvo range and beyond to find what fits budget the best.

Tips to maximize efficiency

The S90’s turbocharged and supercharged engine responds well to smooth throttle inputs. Avoid aggressive acceleration and hard braking, as these driving habits will significantly reduce fuel economy. Anticipate traffic flow and maintain a steady speed whenever possible. The eight-speed automatic transmission is programmed to shift efficiently, so allow it to do its job without abrupt throttle changes.

Ensure that your S90’s tires are properly inflated. Underinflated tires increase rolling resistance, which leads to lower fuel economy. Check your tire pressure regularly and inflate to the recommended pressure listed on the driver’s side doorjamb. A few minutes spent on tire maintenance can translate into noticeable fuel savings.

Minimize idling time. If you’re stopped for more than a minute, it’s more fuel-efficient to turn off the engine. Modern engines are designed to restart quickly and reliably, and the fuel saved by avoiding idling can add up over time, particularly in city driving.

Consider using the S90’s “Eco” driving mode, if equipped. This mode alters the engine and transmission programming to prioritize fuel efficiency. While it may slightly reduce throttle response, it can help you achieve better MPG in everyday driving conditions.
