The 2023 Volvo S90 T8 AWD Recharge extended range achieves 30 MPG combined, a respectable figure. It won’t win any hypermiling contests, but it balances performance, luxury, and a nod toward lower fuel costs. The S90 T8 isn’t bought by people solely focused on squeezing every last mile from a gallon, it’s chosen by professionals, executives, and families who appreciate Scandinavian design, reliable safety features, and the quiet of a well-isolated cabin with the added benefit of all-electric driving capability. Their priorities are clear, and fuel economy is one factor in a much bigger equation.

City and highway performance

The EPA estimates for the S90 T8 Recharge break down to 28 MPG in the city and 33 MPG on the highway. The city number reflects the benefits of the plug-in hybrid system. The electric motor handles much of the low-speed driving, stop-and-go traffic, and initial acceleration, reducing the reliance on the gasoline engine in these situations. The highway rating, while still good, showcases the gasoline engine’s role at higher speeds. The engine works with the electric motor to provide passing power and maintain steady cruising speeds, but the electric driving range is largely depleted at consistent highway speeds. Drivers traveling long distances at a constant clip will likely see fuel consumption closer to a conventional gasoline-powered sedan during that portion of the journey.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Volvo S90 T8 AWD Recharge at $1,950. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, and using the EPA’s estimate of average fuel prices. Remember that this is an estimate. If you primarily drive short distances and consistently charge the battery, you’ll likely spend far less. Conversely, if you frequently take long road trips without plugging in, your real-world fuel expenses could exceed this amount since you burn gasoline after depleting the electrical charge.

Real-world expectations

The flexibility of a plug-in hybrid like the S90 T8 Recharge is a great feature. Those with short commutes and access to charging at home or work can significantly reduce their gasoline consumption, potentially driving almost exclusively on electric power. Volvo claims an all-electric range of up to 38 miles for this vehicle.

In real-world conditions, factors like temperature, driving style, and terrain will affect the actual range. Aggressive acceleration, driving on inclines, or using climate control can all reduce the electric range. When the battery is depleted, the S90 T8 operates as a conventional hybrid, relying on the gasoline engine and electric motor to optimize fuel economy, but without the advantage of pure electric driving.

How it compares

The S90 T8 Recharge competes in a segment that increasingly values electrification. The BMW 530e, another plug-in hybrid sedan, achieves 25 MPG combined. The Mercedes-Benz E350e is no longer available for the 2023 model year, but previously offered similar plug-in hybrid performance with similar fuel economy numbers. The Lexus ES 300h hybrid, though not a plug-in, achieves around 44 MPG combined making the S90 a less economic choice. Buyers considering these vehicles often weigh the benefits of all-electric range against factors like driving dynamics, interior appointments, and brand cachet. The all-wheel drive capability offered by the Volvo makes it a slightly more appealing option in colder weather climates where the other vehicles on the market may only offer front-wheel-drive.

Tips to maximize efficiency

Make the most of the electric driving range by plugging in whenever possible. Even a partial charge can reduce your reliance on the gasoline engine. Installing a Level 2 charger at home will significantly decrease charging times compared to using a standard 120V outlet.

Drive in “Pure” mode whenever conditions allow. This prioritizes electric driving, maximizing your fuel savings. But, be mindful of the limitations, aggressive acceleration will force the gasoline engine to kick in.

Use the regenerative braking feature effectively. It captures energy during deceleration and sends it back to the battery. Anticipate stops and coast whenever possible to maximize energy recovery.

Keep your tires properly inflated. Low tire pressure increases rolling resistance, reducing fuel economy. Check your tire pressure regularly and inflate them to the recommended levels.

Reduce unnecessary weight in the vehicle. Extra cargo adds to the load the engine and motor must haul, decreasing efficiency. Remove any unnecessary items from the trunk and backseat.
