A combined 23 MPG isn’t going to win any awards, but for the 2024 Volvo XC90 B6 AWD, it’s a reasonable compromise. This isn’t a sports car or a hybrid; it’s a substantial, three-row luxury SUV designed to haul families and cargo safely and comfortably in virtually any weather. XC90 B6 shoppers prioritize safety, Scandinavian design, and a premium experience. Fuel economy is a consideration, but it often takes a back seat to these other factors.

City and highway performance

The XC90 B6’s EPA ratings are 20 MPG in the city and 26 MPG on the highway. The city figure reflects the stop-and-go nature of urban driving, which can noticeably impact fuel consumption for any vehicle, especially one of this size. The supercharged and turbocharged 2.0L four-cylinder engine, while surprisingly potent, needs to work harder to get the XC90 moving from a standstill.

The highway number is more palatable. It indicates that the XC90 can cruise efficiently on longer journeys, taking advantage of its overdrive gearing and relatively stable speeds. This is the kind of performance you’d expect during family road trips, where the XC90 shines as a comfortable and capable long-distance cruiser.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,500 for the 2024 Volvo XC90 B6 AWD. This figure is based on driving 15,000 miles per year and using the prevailing national average fuel price for premium gasoline (as the B6 engine requires premium fuel for optimal performance). This is an estimate, and any individual driver’s actual costs may vary. Factors like local fuel prices, driving style, and the percentage of city versus highway driving will all play a significant role in determining the total annual fuel expenditure. You can also view XC90 MPG across all years to analyze historical trends.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy for the XC90 B6 can vary. Aggressive driving habits, frequent short trips where the engine doesn’t fully warm up, and carrying heavy loads will all negatively impact fuel consumption. Conversely, gentle acceleration, consistent highway speeds, and diligent maintenance can help you achieve figures closer to the EPA estimates. Owners on online forums often report a range of 18-24 MPG in mixed driving. All-wheel drive systems, while beneficial for traction, can also slightly reduce fuel efficiency compared to front-wheel drive vehicles.

How it compares

In the competitive world of three-row luxury SUVs, the XC90 B6’s fuel economy falls somewhere in the middle. The Acura MDX SH-AWD, for example, achieves a combined 21 MPG. The BMW X5 xDrive40i gets around 23 MPG combined. The Lexus RX 350L is rated at 21 MPG combined, while a Mercedes-Benz GLE 450 4MATIC manages around 22 MPG combined. The Volvo doesn’t offer a V6 or V8 engine, equipping all trims with variations of a 2.0L 4-cyl engine.

This comparison matters to the buyer weighing the XC90’s strengths against its rivals. It helps define the XC90’s position in the market, showcasing where it excels and where it makes the necessary tradeoffs to deliver its unique blend of luxury, safety, and practicality.

Tips to maximize efficiency

The XC90’s B6 engine benefits from smooth, gradual acceleration. Avoid sudden bursts of speed, especially from a standstill. The supercharger and turbocharger work together to provide power, but excessive demand will quickly drain fuel. Anticipate traffic flow and maintain a consistent speed whenever possible.

Ensure that your tires are properly inflated to the recommended pressure, which can be found on a sticker inside the driver’s side doorjamb or in the owner’s manual. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check tire pressure regularly, especially during temperature changes.

Reduce unnecessary weight in the vehicle. Carrying around extra cargo adds to the load the engine must move, which directly impacts fuel economy. Remove any items you don’t need, freeing up space and improving efficiency. When buying groceries or supplies, plan your route to ensure you go straight home after, rather than sitting in traffic with the extra weight in the car.

Take advantage of the XC90’s “Eco” driving mode, if equipped. This mode typically adjusts throttle response, transmission shift points, and climate control settings to prioritize fuel efficiency. Be aware that power and acceleration may be slightly reduced in Eco mode, but the fuel savings can be worthwhile for everyday driving.

Regular maintenance is critical for optimal fuel economy. Ensure that the engine is properly tuned, the air filter is clean, and the spark plugs are in good condition. Following the manufacturer’s recommended maintenance schedule will help keep the engine running efficiently and prevent fuel-wasting issues from developing.
