27 MPG combined isn’t going to set any records, but it is a reasonable figure for the 2019 Infiniti QX50 2.0L 4-cyl, a compact luxury crossover aimed at those who prioritize style, comfort, and a touch of sportiness over saving gas. Buyers in this segment are often willing to trade a few MPGs for a more premium experience, and the QX50 delivers with its plush interior, sharp design, and innovative engine technology.

City and highway performance

The EPA estimates for the 2019 QX50’s fuel economy are 24 MPG in the city and 31 MPG on the highway. The city figure reflects the stop-and-go driving conditions common in urban environments, with frequent accelerations and decelerations that require more from the engine. The highway MPG demonstrates the QX50’s efficiency at sustained speeds. This difference in MPG isn’t unique to the QX50; it is typical of most vehicles. The automatic (AV-S8) transmission helps optimize fuel consumption, allowing the engine to operate in its most efficient range whether navigating city streets or cruising on the open road.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2019 Infiniti QX50 2.0L 4-cyl is $2,150. This figure is based on driving 15,000 miles per year and using the national average fuel price at the time the estimate was calculated. Actual fuel costs may vary depending on individual driving habits, local fuel prices, and the type of fuel used. While $2,150 is a useful benchmark, it’s important to personalize this estimate based on your own expected usage.

Real-world expectations

The EPA provides a standardized testing procedure to ensure consistent comparisons across different vehicles. Real-world fuel economy can differ from EPA estimates due to a number of variables. Aggressive driving, frequent short trips, and carrying heavy loads can all negatively impact fuel efficiency. However, smooth acceleration, consistent speeds, and proper tire inflation can help you achieve numbers closer to the EPA’s figures. Altitude, weather conditions, and even the brand of gasoline can subtly influence your MPG.

How it compares

The 2019 QX50’s fuel economy is comparable to its competition but doesn’t lead the pack. The Acura RDX, for example, boasts a combined EPA rating of 24 MPG with its standard 2.0L turbo engine and offers a more engaging driving experience for some. The Lexus NX 300h hybrid achieves a remarkable 31 MPG combined, but sacrifices performance for its improved efficiency. Even a non-hybrid like the BMW X3 xDrive30i achieves a combined 25 MPG. Choosing the QX50 represents a balance: it’s more efficient than some of the thirstier options but doesn’t aim for the extreme efficiency of hybrid rivals. Don’t forget to check QX50 MPG across all years to see how the 2019 model compares to others. You can also view all Infiniti fuel economy data to get a broader view.

Tips to maximize efficiency

The QX50 is equipped with a Variable Compression Turbo engine, an innovative design for improved efficiency. To ensure optimal performance from this engine, use premium fuel, as recommended by Infiniti. While it may be tempting to use regular fuel, premium gasoline allows the engine to operate at its peak efficiency, potentially leading to better fuel economy and performance over the long run.

Pay attention to your driving style. The QX50’s engine responds well to smooth and gradual acceleration. Avoid hard acceleration and braking, as these actions consume more fuel. Anticipate traffic flow and maintain a steady speed whenever possible. The adaptive cruise control system can also assist in maintaining consistent speeds on the highway, improving fuel economy.

Regular maintenance is critical for maintaining optimal fuel efficiency. Ensure that your tires are properly inflated to the recommended pressure, as underinflated tires can increase rolling resistance and reduce MPG. Also, schedule regular oil changes and air filter replacements, as a clean engine runs more efficiently. A well-maintained QX50 will not only perform better but deliver better fuel economy.

Minimize unnecessary weight. Carrying heavy loads in your QX50 can negatively impact fuel efficiency. Remove any unnecessary items from the trunk and passenger compartment to reduce weight. Even small amounts of extra weight can add up over time, so lighten the load to maximize your MPG. This is especially important if you frequently use your QX50 for hauling cargo or passengers.
