25 MPG combined is a respectable figure for the 2017 Volvo XC90 T8 AWD PHEV, even if it won’t win any hypermiling competitions. The XC90 T8 is more than just an SUV. It’s for the buyer who wants luxury, space, and less gas without sacrificing performance. These are often families in affluent suburbs who value safety, design, and having a plug-in hybrid that makes them feel a bit better about dropping kids at school and taking weekend trips.

City and highway performance

The XC90 T8 has two distinct personalities on the road, and the city/highway MPG figures show this. 24 MPG in the city suggests how often the 2.0-liter engine is needed to help the electric motor when dealing with stop-and-go traffic or accelerating from a standstill. However, 27 MPG on the highway reveals the potential for efficiency when the electric motor can contribute more at cruising speeds. The 8-speed automatic transmission also plays a crucial role here, keeping the engine in its optimal power band for both performance and fuel savings. This split highlights the T8’s character as a hybrid designed to make the most of regenerative braking and electric assist in urban environments, while still being a capable highway cruiser.

Annual fuel cost

The EPA estimates that the average owner of a 2017 Volvo XC90 T8 AWD PHEV can expect to spend approximately $2,300 per year on fuel. This calculation is based on driving 15,000 miles annually, using a blend of city and highway driving, and relies on national average fuel prices. Keep in mind that this figure is just an estimate; your actual fuel costs may vary depending on your driving habits, the price of gasoline in your area, and how often you charge the battery. The calculation assumes you don’t use the electric range regularly, so owners who diligently plug in their T8 may see lower fuel expenses.

Real-world expectations

The fuel economy of any plug-in hybrid is hugely dependent on driving style and charging habits. Owners who consistently plug in and use the electric range of the XC90 T8 will see significantly better fuel economy than those who treat it only as a hybrid. Short trips around town can often be completed entirely on electric power, resulting in zero gasoline consumption. However, longer trips and aggressive driving will rely more on the gasoline engine, bringing fuel economy closer to the EPA estimates. Weather conditions, like extremely cold temperatures, can also impact battery performance and reduce electric range, leading to increased fuel consumption. Reviewing information about XC90 MPG across all years can help you understand trends in real-world owner reporting.

How it compares

Compared to other luxury three-row SUVs, the 2017 Volvo XC90 T8 AWD PHEV performs well. The non-hybrid XC90 variants, like the T6, achieved around 22 MPG combined. The BMW X5 xDrive40e – another plug-in hybrid SUV – landed around 24 MPG combined. The Acura MDX, a non-hybrid option, typically delivers about 22 MPG combined. What makes the T8 different is the ability to drive on pure electric power for a limited range. For buyers prioritizing fuel efficiency and lower emissions, the T8 is a good option in a segment often criticized for its thirst. For more context, review all Volvo fuel economy data.

Tips to maximize efficiency

Use the available drive modes. The XC90 T8 offers modes such as “Pure” (electric only), “Hybrid” (blends electric and gasoline power), and “Power” (prioritizes performance). Choose “Pure” for short, low-speed trips around town to maximize electric range and minimize fuel consumption.

Drive smoothly and avoid aggressive acceleration and braking. This is particularly important for maximizing the efficiency of the regenerative braking system, which recovers energy during deceleration and recharges the battery. Anticipate traffic flow and maintain a consistent speed whenever possible.

Plug in regularly! This might seem obvious, but consistently charging the battery is the key to unlocking the XC90 T8’s full fuel-saving potential. Aim to charge the battery overnight or whenever the vehicle is parked for an extended period. A full battery means more electric range and less reliance on the gasoline engine.

Monitor your driving data. The XC90 provides information on your energy consumption and driving patterns. Use this data to identify areas where you can improve your efficiency, such as reducing idle time or adjusting your acceleration habits.
