25 MPG combined in the 2019 Volvo XC90 T8 eAWD Plug-In Hybrid isn’t going to win any hypermiling contests, but it’s a figure that appeals to its target audience: affluent, safety-conscious families who prioritize versatility and Scandinavian luxury over outright fuel efficiency. These are buyers for whom the XC90’s plug-in hybrid system represents efficient commuting, not necessarily a full embrace of electric driving. They need three rows, available all-wheel drive, and the reputation of the Volvo brand, and they’re willing to pay for it.

City and highway performance

The EPA estimates the 2019 XC90 T8 achieves 24 MPG in the city and 27 MPG on the highway. These numbers reflect the vehicle’s complex powertrain. The XC90 T8 uses a 2.0L four-cylinder engine that is both supercharged and turbocharged, in addition to an electric motor powered by a plug-in battery pack. The electric side of the equation is primarily designed to boost overall efficiency, especially during stop-and-go city driving, but the relatively limited all-electric range means drivers will primarily rely on the gasoline engine. With its 8-speed automatic transmission, the XC90 T8 delivers smooth power on the open road, but drivers shouldn’t expect Prius-level fuel sipping.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2019 Volvo XC90 T8 eAWD Plug-In Hybrid is approximately $2,300. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Fuel costs can vary based on driving habits and local fuel prices. Those who diligently plug in and maximize the electric range will likely see significantly lower annual fuel costs, while those who treat the hybrid system as simply a power booster will find their real-world expenses aligning more closely with that $2,300 figure. For drivers interested in lowering their fuel costs further, they may want to examine all Volvo fuel economy data.

Real-world expectations

While the EPA provides a standardized baseline, real-world fuel economy for the XC90 T8 varies considerably based on driving habits. Frequent charging is key. Drivers who consistently plug in and use the electric range for shorter trips can expect to see MPG figures far exceeding the EPA estimates, however, longer road trips, or neglecting to charge regularly, will result in fuel economy that aligns closely with a traditional gasoline-powered SUV. Aggressive driving will also negatively impact fuel economy, so a gentle foot is recommended to maximize efficiency. Also, external temperatures might affect electric range which similarly affects real-world range.

How it compares

The XC90 T8 competes in a crowded field of luxury SUVs. A comparable non-hybrid model, like the Acura MDX SH-AWD, delivers around 22 MPG combined. The BMW X5 xDrive40i achieves approximately 23 MPG combined, while the Audi Q7 earns near 20 MPG combined. Those are good vehicles, but not PHEVs, therefore, direct comparisons may be difficult. While the Infiniti QX60 gets decent fuel economy alone at 23 MPG combined, it can’t be plugged in. The Lexus RX 450h, rated at 31 MPG combined, demonstrates that some hybrid SUVs offer superior fuel economy. However, the RX 450h prioritizes efficiency over the XC90’s combination of luxury, performance, and electric capability. To explore XC90 MPG across all years, there are many ways to get the fuel economy of that specific model.

Tips to maximize efficiency

Prioritize charging the XC90 T8 whenever possible. Plug in at home overnight, and use public charging stations when available. Using these actions allows the electric motor to handle a larger percentage of your driving which significantly reduces fuel consumption.

Use the XC90’s selectable drive modes. Engage the “Pure” mode for electric-only driving when appropriate, especially for shorter trips. “Hybrid” mode balances electric and gasoline power for optimal efficiency, while “Power” mode prioritizes performance over economy, so save it for when you truly need it.

Practice smooth acceleration and braking. Avoid aggressive driving habits, as these will quickly deplete the battery and force the gasoline engine to work harder thus resulting in poor MPG. Gentle acceleration and regenerative braking will help maximize energy recovery.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended level, which can be found on a sticker inside the driver’s side door. Regular maintenance is required to get optimal fuel efficiency.
