25 MPG combined isn’t going to set the world on fire, but it’s a reasonable compromise for the 2024 Infiniti QX50 AWD. This isn’t a fuel-sipping hybrid, nor is it a lumbering, truck-based SUV. It’s a stylish, comfortable, and technologically advanced compact crossover aimed at buyers who prioritize luxury and a refined driving experience over outright fuel efficiency. These buyers are often empty-nesters or small families who value the QX50’s premium interior, distinctive aesthetics, and standard all-wheel drive for added confidence in various weather conditions. They understand that performance and luxury often come with a slight trade-off in fuel economy, and the QX50’s numbers fall squarely within their acceptable parameters.

City and highway performance

The EPA estimates the QX50 AWD achieves 22 MPG in the city and 28 MPG on the highway. This spread reflects the characteristics of its 2.0-liter VC-Turbo four-cylinder engine. In urban environments, stop-and-go traffic and lower speeds tend to emphasize the engine’s need to work harder, thus reducing efficiency. On the open road, however, the engine operates more consistently at optimal speeds, allowing the variable compression system to deliver better fuel economy. The smooth-shifting automatic (AV-S8) transmission further contributes to highway efficiency by keeping the engine in its sweet spot and minimizing unnecessary downshifts.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2024 Infiniti QX50 AWD is $2,300. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s a benchmark that allows potential buyers to compare the QX50’s running costs against other vehicles in its class and factor fuel expenses into their overall budget considerations. While individual fuel costs will vary depending on driving habits and local fuel prices, the $2,300 estimate provides a standardized point of reference.

Real-world expectations

While the EPA estimates provide a useful comparison tool, remember that real-world fuel economy will vary based on individual driving habits, road conditions, and even tire pressure. Aggressive acceleration, frequent hard braking, and carrying heavy loads can all significantly impact fuel consumption in the QX50. Drivers who primarily travel in congested city environments may find their average MPG closer to the EPA’s city estimate, while those who frequently take long highway trips could potentially exceed the EPA’s highway figure. Regular maintenance, including timely oil changes and proper tire inflation, is critical for maintaining optimal fuel efficiency.

How it compares

In the competitive compact luxury SUV segment, the QX50’s fuel economy is generally in line with other AWD models. For example, the Acura RDX SH-AWD achieves a combined EPA rating of 23 MPG, while the Volvo XC60 B5 AWD manages 25 MPG combined, matching the QX50. The Lexus NX 350 AWD is rated at 25 MPG combined, as well. The BMW X3 xDrive30i is rated at 24 MPG combined. The QX50 buyer isn’t necessarily chasing the absolute best MPG; they’re seeking a balance between luxury, performance, and fuel efficiency, and the Infiniti presents a good package in this regard. Many buyers cross-shop the QX50 MPG across all years against these competitors.

Tips to maximize efficiency

Take advantage of the QX50’s drive mode selector. Selecting “Eco” mode adjusts the engine and transmission settings to prioritize fuel efficiency. While it might slightly reduce acceleration responsiveness, it can make a noticeable difference in fuel consumption, especially during everyday commuting.

Ensure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and maintain the recommended levels to optimize fuel economy and tire life.

Avoid aggressive driving habits such as rapid acceleration and hard braking. Smooth, consistent driving minimizes fuel consumption. Anticipate traffic flow and maintain a steady speed whenever possible to maximize fuel efficiency.

Reduce unnecessary weight in the vehicle. Carrying extra cargo increases the load on the engine and negatively impacts fuel economy. Remove any items you don’t need, especially heavier objects, to improve efficiency. Remember to check all Infiniti fuel economy data to compare past years to your potential vehicle.

Consider using cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy on long drives. However, be mindful of hills and traffic conditions, and be prepared to disengage cruise control if necessary to maintain a safe and consistent speed.
