25 MPG combined is an acceptable figure for the 2023 Infiniti QX50 AWD 2.0L 4-cyl, a luxury crossover that prioritizes style, comfort, and technology over saving on fuel. This isn’t a hybrid designed to sip fuel; it’s a premium vehicle for buyers who value a refined driving experience and ample cargo space. They’ll accept this fuel economy rating because it allows them to enjoy a luxurious ride without excessive trips to the gas station.

City and highway performance

The 2023 Infiniti QX50 AWD earns an EPA-estimated 22 MPG in the city and 28 MPG on the highway. The city rating reflects the demands of stop-and-go traffic, where the QX50’s turbocharged engine and all-wheel-drive system work harder. The highway rating, achieved at steady speeds, demonstrates the engine’s efficiency when cruising. The continuously variable transmission (AV-S8) aims to hold the engine in its most efficient range, but it is a CVT, and that inherently affects driver feel and perhaps makes the driver push harder on the accelerator than they otherwise would.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2023 Infiniti QX50 AWD is approximately $2,300. This figure 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, local fuel prices, and the type of gasoline you use. Premium fuel is recommended for optimal performance in the QX50, affecting the real-world fuel cost.

Real-world expectations

The EPA estimates provide a good baseline, but real-world fuel economy can fluctuate. Aggressive driving, carrying heavy loads, and operating the climate control system can all decrease fuel efficiency. Gentle acceleration, consistent speeds, and proper tire inflation can help you achieve or even exceed the EPA estimates. Expect to see figures closer to the city MPG rating if you spend most of your time in stop-and-go traffic. The 28 MPG highway rating should be within reach if you frequently embark on long highway journeys.

How it compares

The QX50 competes in a crowded market, and its fuel economy stacks up differently depending on the rival. The Acura RDX SH-AWD achieves 23 MPG combined, a slight advantage for the Infiniti. Some might cross-shop this car with the Lexus NX 350h AWD. The NX hybrid is slower than the QX50, but it’s far more efficient with a 39 MPG combined rating that shames the QX50. Even the BMW X3 xDrive30i is rated at 24 combined MPG, not far off the Infiniti’s pace. This comparison speaks to the buyer’s priorities. If fuel economy is important, a hybrid option like the Lexus NX is a better choice. The QX50 remains a strong contender if the buyer values a balance of luxury, performance, and space. For those seeking all Infiniti fuel economy data or QX50 MPG across all years, resources are readily available.

Tips to maximize efficiency

Use the QX50’s Eco drive mode. This setting adjusts engine and transmission mapping to prioritize fuel efficiency, smoothing out throttle response and encouraging earlier upshifts. The fuel savings can be noticeable, especially during city driving, though it might slightly dampen the vehicle’s responsiveness.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy and accelerates tire wear. Check your tire pressure regularly and inflate them to the recommended pressure listed on the sticker inside the driver’s side doorjamb. Even a few PSI below the recommended level can impact fuel consumption.

Anticipate traffic flow and practice smooth driving techniques. Avoid sudden acceleration and hard braking, as these actions consume more fuel. Look ahead, maintain a steady speed, and allow ample space between your vehicle and the one in front of you. This approach improves fuel economy and enhances safety.

Minimize idling. Turn off the engine if you anticipate being stopped for more than a minute. Idling consumes fuel and produces unnecessary emissions. The QX50 does not have an auto stop/start function, so the driver has full control over this. Restarting the engine consumes a negligible amount of fuel compared to prolonged idling.
