The 2015 Infiniti QX60 AWD with its 3.5L V6 engine achieves 22 MPG combined fuel economy. While this isn’t the most efficient in its class, many QX60 buyers find it acceptable because the vehicle offers comfortable seating for seven, a luxurious interior, and the added security of all-wheel drive. Owners prioritize space, safety, and elegance over maximizing fuel savings, and the QX60 hits a sweet spot for many families.

City and highway performance

The EPA rates the 2015 Infiniti QX60 AWD at 19 MPG in the city and 26 MPG on the highway. The city figure reflects the increased demands on the powertrain in stop-and-go traffic, where the QX60’s weight and the energy required to repeatedly accelerate use more fuel. The highway rating is better. At a constant speed, the V6 engine settles into a more efficient rhythm, and the continuously variable transmission (CVT) helps optimize fuel consumption. However, even on the highway, expect those numbers to drop if you’re frequently overtaking or driving at higher speeds. Getting that 26 MPG requires a gentle foot and a relaxed driving style.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Infiniti QX60 AWD at $2,650. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on your driving habits and the price of gasoline in your area, of course. Someone who drives primarily in the city will likely spend significantly more than $2,650, while someone who drives mostly highway miles could spend slightly less. This estimate also assumes you’re using the recommended fuel grade, which greatly impacts long-term engine performance and that MPG figure.

Real-world expectations

While the EPA provides a standardized benchmark, real-world fuel economy often differs. QX60 owners commonly report averaging between 18 and 24 MPG in mixed driving conditions. Driving style, traffic, and even the weather can all influence fuel consumption. Aggressive acceleration and frequent braking will certainly lower your MPG. Headwinds and cold temperatures can also decrease your fuel mileage. Consistently exceeding the speed limit is another way to burn through fuel faster. Keeping your tires properly inflated and performing regular maintenance are critical for maintaining optimal fuel economy.

How it compares

The 2015 Infiniti QX60’s fuel economy is generally competitive within its class, but it’s important to consider the alternatives. For example, the Acura MDX SH-AWD, another popular three-row luxury SUV, achieves a slightly better 21 MPG combined thanks to its more advanced engine and transmission. The Lexus RX 350 AWD, while only offering two rows, boasts a similar 22 MPG combined rating. The Volvo XC90 T6 AWD from the same year offers a slightly lower 20 MPG combined, but it compensates with a more modern interior and enhanced safety features. Browsing all Infiniti fuel economy data will allow you to see how Infiniti’s other models compare. Understanding these differences is important for buyers weighing fuel costs against other factors like space, luxury, and brand preference. If fuel economy is your top priority, you might want to explore hybrid options or smaller SUVs. You can also compare QX60 MPG across all years to identify potential gains in other model years.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel economy in the QX60. Avoid pressing hard on the gas pedal, especially from a stop. The CVT transmission is designed to keep the engine in its most efficient operating range, but rapid acceleration forces it to work harder and burn more fuel. Ease into the throttle and let the transmission do its job.

Maintaining a steady speed on the highway will also contribute to better MPG. Cruise control can help you do this. It helps avoid speed fluctuations that waste fuel. Pay attention to the traffic ahead and anticipate changes in speed, rather than constantly accelerating and decelerating.

Keep your tires properly inflated. Under-inflated tires increase rolling resistance, which forces the engine to work harder and reduces fuel economy. Check your tire pressure regularly, especially during temperature changes, and maintain the recommended pressure listed on the driver’s side doorjamb.

Avoid carrying unnecessary weight in the vehicle. The QX60 is already a fairly heavy vehicle, so any extra cargo will only make it work harder. Remove any items you don’t need from the trunk or cargo area. Even small amounts of extra weight can add up and negatively impact fuel economy over time.

Regular maintenance is essential for optimal fuel economy. Keep your engine properly tuned and change the air filter regularly. A clean air filter allows the engine to breathe easier, which improves performance and fuel efficiency. Follow the maintenance schedule outlined in your owner’s manual.
