The 2022 Infiniti QX55 AWD 2.0L 4-cyl gets a combined 25 MPG. Most people buy it for its striking coupe-like roofline and luxurious interior, not fuel savings. For those attracted to its unique style, this efficiency is an acceptable trade-off. It’s a price they’re willing to pay to stand out from the many crossover SUVs.

City and highway performance

The EPA estimates the QX55 will get 22 MPG in city driving and 28 MPG on the highway. The city figure reflects stop-and-go traffic, where the 2.0L turbocharged engine works harder, and the automatic transmission shifts often. The highway number is better, suggesting longer trips at steady speeds will result in better fuel consumption. While 28 MPG is average for this class, it shows the engine’s ability to perform well when cruising. Drivers who commute mostly in cities will probably see fuel economy closer to 22 MPG.

Annual fuel cost

The EPA says the annual fuel cost for the 2022 Infiniti QX55 AWD is $2,300. This is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. Individual spending will vary. Drivers who drive more miles or live in areas with higher fuel costs will spend more, while those who drive less or live in areas with lower prices will spend less. This calculation doesn’t include changes in gasoline prices throughout the year, which can significantly affect your overall costs.

Real-world expectations

The EPA provides a standard, but real-world fuel economy differs based on driving style, road conditions, and vehicle maintenance. Hard acceleration, frequent hard braking, and carrying heavy loads will decrease fuel efficiency. Gentle driving habits, proper tire inflation, and regular maintenance can help you reach or exceed the EPA estimates. Expect to see figures between 22 and 28 MPG in everyday driving, with 25 MPG as a general guideline. The amount of gas consumed can also be affected by weather conditions like cold temperatures or strong headwinds.

How it compares

For a luxury crossover with sporting aims, the QX55’s fuel economy is about average. The Acura RDX, another strong competitor, gets 23 MPG combined in its standard front-wheel-drive configuration, or 21 MPG with all-wheel drive. The Lexus NX 350h hybrid achieves a much better 39 MPG combined, appealing to buyers who want less gas above all else. You might also consider the BMW X4, which delivers around 24 MPG combined in its base xDrive30i trim. These comparisons highlight the trade-offs in this vehicle class: style and performance versus efficiency. For a complete view, check out all Infiniti fuel economy data.

Tips to maximize efficiency

The QX55’s VC-Turbo engine works best with smooth, consistent use of the accelerator. Avoid hard acceleration and sudden braking when possible. Watch traffic and maintain a steady speed to use less gas. This driving style is effective on the highway, where the engine can operate more efficiently at a consistent cruising speed.

Make sure your tires are inflated to the recommended pressure. Underinflated tires increase rolling resistance, which lowers fuel economy. Check your tire pressure regularly and adjust as needed, especially when the temperature changes. Proper tire inflation also improves handling and extends the life of your tires.

Remove any unnecessary weight from the vehicle. Extra cargo puts strain on the engine, increasing gas consumption. Keep the cargo area organized and remove items that are not needed for your daily commute. Every little bit helps.

The QX55 has drive modes that can affect fuel economy. Explore the settings and try the vehicle’s Eco mode. This mode adjusts throttle response and transmission shift points to prioritize fuel efficiency. It might slightly reduce performance, but it can make a difference in fuel consumption, especially during city driving.

Regular maintenance is important for good fuel economy. Make sure your engine air filter is clean, your spark plugs are in good condition, and your oil is changed as recommended by the manufacturer. These factors affect engine performance and fuel efficiency. Ignoring maintenance can reduce MPG and cause more serious mechanical problems.
