23 MPG combined isn’t spectacular, but many owners of the 2015 Infiniti QX60 FWD find it an acceptable trade-off for the luxury, comfort, and space the crossover offers. Families buy this vehicle when they prioritize a smooth ride, a quiet cabin, and three rows of seating. The QX60 is about transporting people in comfort, and its fuel economy, while not the best, supports that objective.

City and highway performance

The EPA estimates for the 2015 Infiniti QX60 FWD are 21 MPG in the city and 27 MPG on the highway. The city figure reflects the stop-and-go conditions many QX60s experience daily when driving kids to school, running errands, and navigating suburban traffic. The 27 MPG highway rating is more achievable during steady cruising, fitting longer road trips where the QX60’s comfortable seats and quiet interior are appreciated. This difference suggests the QX60 is most efficient on long journeys at consistent speeds, which helps families taking road trips to minimize stops. A light touch on the accelerator is the key, as the 3.5-liter V6 can quickly use fuel when pushed hard.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 Infiniti QX60 FWD is $2,500. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs may vary depending on your driving habits, the type of fuel you use, and local gas prices. Aggressive driving, frequent short trips, or using premium fuel when it’s not required can all increase your yearly fuel expenditure beyond this estimate.

Real-world expectations

The EPA figures provide a useful starting point, but real-world QX60 MPG often varies, as with all vehicles. Many owners report achieving numbers close to the EPA estimates, especially on longer trips. However, frequent city driving or aggressive acceleration can easily drop the combined MPG into the high teens or low twenties. Factors like tire pressure, vehicle maintenance, and cargo weight can also incrementally affect fuel consumption.

How it compares

The 2015 Infiniti QX60 FWD is near the middle compared to its competitors. The Acura MDX, for example, achieves an EPA-estimated 20 city/28 highway MPG. This makes the Acura slightly more efficient on paper, but the real-world difference might be negligible for those who prioritize the Infiniti’s styling or interior. The Lexus RX 350 offers similar fuel economy to the QX60. Buyers should compare QX60 MPG across all years to understand the progression of efficiency in this model line.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel economy in the QX60. The 3.5-liter V6 provides ample power, but using it carefully will mean fewer trips to the gas station. Avoid abrupt starts and stops, and try to maintain a steady speed when possible. Let the continuously variable transmission (CVT) work by keeping the engine in its most efficient range. You don’t need to floor it to merge onto the highway; smooth acceleration is best.

Regular maintenance, especially tire inflation and oil changes, significantly impacts fuel efficiency. Underinflated tires increase rolling resistance, forcing the engine to work harder. Also, old or dirty engine oil can reduce efficiency. Following the manufacturer’s recommended maintenance schedule will help keep your QX60 running well.

Reduce unnecessary weight. The QX60 is already fairly heavy, so don’t carry extra cargo that you don’t need. Remove roof racks or cargo carriers when they’re not in use because they can increase aerodynamic drag. A lighter vehicle requires less energy to move, resulting in better fuel economy.

Consider using the QX60’s drive mode selector, if it has one, to prioritize fuel efficiency when you can. Some models offer an “Eco” mode that adjusts throttle response and transmission settings to optimize fuel consumption. While this mode may reduce performance slightly, it can make a noticeable difference during everyday driving. Experiment to see if the result is worth it for your typical commute.
