The 2023 Infiniti QX60 FWD 3.5L V6 achieves 23 MPG combined fuel economy. While not the best in its class, this is an acceptable trade-off for buyers who want a luxurious three-row SUV with a reliable engine instead of prioritizing maximum fuel savings. The QX60 is for families who value comfort, space, and a touch of elegance; for those buyers, the fuel consumption is within reasonable expectations.

City and highway performance

The EPA estimates that the QX60 FWD gets 21 MPG in the city and 26 MPG on the highway. The city figure reflects stop-and-go traffic, where the QX60’s 3.5-liter V6 and nine-speed automatic transmission work harder. On the open road, the 26 MPG highway rating is more attainable, especially when using cruise control and driving at a steady speed. This difference between city and highway MPG highlights the QX60’s preference for longer journeys over dense urban environments. The nine-speed transmission allows relaxed cruising at highway speeds, keeping the engine in its most efficient operating range.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,500 for the 2023 Infiniti QX60 FWD. This calculation is based on driving 15,000 miles per year and national average fuel prices. Individual driving habits and local fuel costs will impact the actual amount spent on fuel, with aggressive driving and higher fuel prices increasing the annual expense. However, this figure is a useful benchmark for budgeting and comparing the QX60’s running costs against other vehicles in its class and can offer a better understanding of QX60 MPG across all years.

Real-world expectations

EPA estimates provide a standardized benchmark, but real-world fuel economy can change. Expect to see figures fluctuate based on driving style, terrain, and vehicle load. Consistent hard acceleration, frequent short trips, and carrying heavy loads will reduce fuel economy. On the other hand, gentle acceleration, highway cruising, and regular maintenance can help to achieve, or even slightly exceed, the EPA estimates. Many drivers report that exceeding the highway rating is possible by driving conservatively, and the QX60’s trip computer can provide helpful feedback on driving habits and their impact on fuel consumption.

How it compares

The Infiniti QX60’s fuel economy is competitive, but not class-leading. The Acura MDX FWD, for example, achieves a similar 22 MPG combined. The Lexus RX 350 also gets 25 MPG combined. These numbers show that the QX60 is comparable in fuel economy to its direct competitors in the luxury three-row SUV market. Buyers seeking better fuel economy might consider hybrid options like the Acura MDX Sport Hybrid (offering a combined 27 MPG), but that vehicle has a different powertrain and a different character. For buyers who want the dependable V6 of the QX60, the fuel consumption is a trade-off they accept. You can compare all Infiniti fuel economy data to other brands to see where this vehicle stands.

Tips to maximize efficiency

Avoid aggressive acceleration. The QX60’s V6 delivers ample power, but using it freely will reduce fuel economy. Smooth, gradual acceleration is key to maximizing MPG in city driving. Anticipate traffic flow and avoid unnecessary braking to keep the engine in its sweet spot.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressures regularly and inflate them to the recommended levels listed on the driver’s side doorjamb. Correct inflation improves fuel economy and tire life.

Reduce unnecessary weight. Carrying extra cargo adds weight to the vehicle, which reduces fuel efficiency. Remove any unnecessary items from the cargo area and passenger cabin. A lighter vehicle requires less energy to accelerate and maintain speed.

Use cruise control on the highway. Cruise control helps maintain a constant speed, preventing unnecessary acceleration and deceleration. This reduces fuel consumption and makes long-distance driving more efficient. Setting it a few MPH below the speed limit can help optimize fuel economy.

Keep up with scheduled maintenance. A well-maintained engine operates more efficiently. Follow the recommended maintenance schedule for oil changes, air filter replacements, and tune-ups. This ensures that the engine is running smoothly and delivering optimal fuel economy from the 3.5L V6.
