20 MPG combined won’t win any awards, but it’s what you get with the 2016 Infiniti QX50 AWD. It’s not a hybrid or an ultra-efficient crossover. It’s a compact luxury SUV with a strong 3.7-liter V6 sending power to all four wheels. Buyers choose this QX50 for its distinct character and responsive engine, knowing that it impacts fuel costs. This vehicle appeals to a driver who wants spirited performance and a more engaging driving experience than excellent fuel economy.

City and highway performance

The EPA estimates the 2016 Infiniti QX50 AWD at 17 MPG in the city and 24 MPG on the highway. The city figure reflects stop-and-go driving, where the naturally aspirated 3.7-liter engine uses the most fuel. The highway number is more respectable and achievable during steady cruising. The seven-speed automatic transmission helps optimize fuel economy at higher speeds, even though it’s not the most modern transmission. Remember that aggressive driving, even on the highway, will quickly decrease these numbers. The QX50 encourages a heavy foot, and that’s part of its appeal.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Infiniti QX50 AWD at $2,900. This calculation is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. It also assumes national average fuel prices. If you drive significantly more or less than 15,000 miles annually, or if fuel prices in your area are higher or lower than the national average, your actual fuel cost will vary. Consider this figure a useful benchmark for comparing against other vehicles.

Real-world expectations

While the EPA estimates provide a standardized comparison, real-world MPG often differs. QX50 owners often report figures slightly below the EPA estimates, particularly in combined driving. Expect to see closer to 15-16 MPG in the city with enthusiastic driving, and maybe 22-23 MPG on long highway trips if you maintain a reasonable speed. Factors like tire pressure, vehicle maintenance, and even the grade of gasoline can influence your actual fuel economy.

How it compares

Compared to its contemporaries, the 2016 Infiniti QX50 AWD’s fuel economy is on the lower end. The Acura RDX, for example, with its V6 engine and available all-wheel drive, achieves around 22 MPG combined. Even the more powerful BMW X3 xDrive28i, with its turbocharged four-cylinder, manages similar numbers, hovering around 24 MPG combined. A Lexus NX 200t with all-wheel drive is often seen surpassing 25 MPG combined. Buyers considering brands like Infiniti understand they are often trading MPGs for a more refined driving experience; for shoppers prioritizing fuel efficiency, alternatives like the Lexus NX hybrid offer a compelling alternative, regularly exceeding 30 MPG combined. For drivers interested in all Infiniti fuel economy data, this will likely be a crucial factor in the purchase decision. Always remember to consider QX50 MPG across all years to understand the whole picture.

Tips to maximize efficiency

Gentle acceleration is best. The QX50’s 3.7-liter V6 responds eagerly to throttle input, but resist flooring it at every opportunity. Gradual acceleration will significantly improve your city MPG.

Use cruise control on the highway. Maintaining a consistent speed minimizes fuel consumption. Setting cruise control even a few miles per hour below the speed limit can further enhance your fuel efficiency.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder. Check your tire pressure regularly and inflate them to the recommended levels, typically found on a sticker inside the driver’s side door jamb.

Regular maintenance is critical. A well-maintained engine runs more efficiently. Follow the manufacturer’s recommended maintenance schedule, including oil changes, air filter replacements, and spark plug replacements.

Reduce unnecessary weight. Carrying excessive cargo in your QX50 adds weight, reducing fuel economy. Remove any unnecessary items from the trunk and cabin to minimize the load on the engine.
