27 MPG combined isn’t the best, but for the 2019 Volvo S90 FWD with its 2.0L 4-cylinder engine, it’s a reasonable mix of luxury, performance, and efficiency. This isn’t a sports car or a hybrid, but a comfortable and stylish sedan aimed at buyers who value Scandinavian design, a refined driving experience, and reasonable running costs. These owners aren’t chasing maximum MPG, but they appreciate knowing they’re not spending too much money at the pump.

City and highway performance

The EPA estimates the S90 at 23 MPG in the city and 35 MPG on the highway. The city number reflects the stop-and-go driving in urban environments, where the S90’s weight and conventional automatic transmission (S8) affect mileage. The highway number shows the benefits of the efficient turbocharged and supercharged 2.0L engine, designed to cruise comfortably at higher speeds. Achieving 35 MPG on the open road is good for a car of this size and class, so long road trips are reasonable.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Volvo S90 FWD at $2,150. This is based on driving 15,000 miles per year and using the national average fuel price. It’s a useful comparison against other vehicles, but individual spending depends on driving habits and local fuel prices. Budget a little more, accounting for potential fuel price increases. This figure is useful when considered along with all Volvo fuel economy data.

Real-world expectations

While the EPA numbers provide a standard, real-world fuel economy can change. Driving style, traffic, and tire pressure affect how efficiently the S90 uses fuel. Hard acceleration and braking will decrease MPG, while smooth driving is best. Your actual MPG may differ from the EPA estimates.

How it compares

Compared to its competitors, the 2019 S90’s fuel economy is competitive. The BMW 530i (FWD) gets around 28 MPG combined, a slight edge over the S90. The Mercedes-Benz E300 (FWD) also gets around 28 MPG combined. Acura’s TLX with the 2.0L turbo engine is generally around 25 MPG combined. The S90’s appeal lies in its design, luxurious interior, and Volvo’s reputation for safety. Buyers in this segment look at the total package, not just the MPG number. For anyone who wants to explore S90 MPG across all years, all the data is here.

Tips to maximize efficiency

The S90 has an “Eco” drive mode. This setting adjusts throttle response and transmission shift points to help fuel efficiency. It might make the car feel slightly less responsive, but it can improve your MPG, especially in city driving.

Keep proper tire inflation. Underinflated tires increase rolling resistance and reduce fuel economy. Check your tire pressure regularly and inflate them to the recommended level, which is on a sticker inside the driver’s side doorjamb.

Avoid idling. If you’re stopped for more than a minute or two, turn off the engine. Modern cars, including the S90, restart quickly, and idling wastes fuel and increases emissions.

Watch traffic. Planning your route lets you keep a consistent speed and avoid unnecessary braking and acceleration, which lower MPG.

Reduce weight. Remove items from the trunk and passenger area. Extra weight makes the engine work harder and consumes fuel. The S90 is for refined cruising, not hauling.
