20 MPG combined won’t win any hypermiling contests, but for the 2016 Infiniti Q70 AWD with the 3.7L V6, it’s a figure luxury sedan buyers often accept in exchange for all-weather capability, spirited performance, and distinctive styling. This isn’t a car purchased purely for its fuel efficiency, it’s bought by those who value a comfortable, well-equipped driving experience with a hint of sporting character. Knowing its target buyer makes this fuel economy more understandable.

City and highway performance

The EPA estimates the 2016 Q70 AWD at 18 MPG in the city and 24 MPG on the highway. The city number reflects stop-and-go driving, where the Q70’s 3.7L V6 and its 7-speed automatic transmission work harder, especially with the added weight and friction of all-wheel drive. The highway figure is more achievable, reached during steady cruising where the engine’s efficiency can shine, assuming a gentle foot.

Drivers who regularly encounter heavy traffic should expect to see numbers closer to the city rating, while those with long highway commutes may nudge closer to the 24 MPG mark.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2016 Infiniti Q70 AWD 3.7L is $2,900. This calculation is based on driving 15,000 miles per year and using the national average fuel price at the time of estimation.

Of course, the actual cost will vary depending on individual driving habits and fluctuating fuel prices. Those who drive more aggressively, spend more time idling, or live in areas with higher fuel costs will spend more than this estimate. Conservative drivers in areas with lower fuel prices may spend less. It is important to consider these factors when budgeting for vehicle ownership.

Real-world expectations

While the EPA numbers provide a benchmark, real-world fuel economy often deviates. Q70 AWD owners report figures that are around the EPA estimates, and some even see slightly better numbers when using specific fuel-saving techniques. However, aggressive driving, frequent short trips, where the engine doesn’t reach optimal operating temperature, and constant use of features like climate control can quickly lower fuel efficiency. Checking forums and owner reviews is a good way to understand the Q70 MPG across all years in real-world scenarios.

How it compares

The 2016 Infiniti Q70 AWD 3.7L faces competition in the luxury sedan segment. The Lexus GS 350 AWD boasts a slightly better combined EPA rating of 22 MPG. The BMW 535i xDrive, with its turbocharged inline-six, achieves a similar 23 MPG combined. The Acura RLX SH-AWD, though less focused on sportiness, manages a respectable 23 MPG combined thanks to its hybrid system. The Audi A6 3.0T Quattro also achieves 24 MPG combined. For buyers prioritizing fuel economy without sacrificing all-wheel drive, these alternatives are choices.

However, these rivals may not offer the styling, features, and price point that draw buyers to the Infiniti Q70. Exploring all Infiniti fuel economy data and comparing with competitor models is a step in any new-car research process.

Tips to maximize efficiency

Gentle acceleration is key to maximizing fuel economy in the Q70. The 3.7L V6 responds readily to throttle input, but avoid aggressive acceleration when possible. Maintain a steady speed on the highway, and avoid constantly changing lanes or tailgating other vehicles. Smooth driving will improve your MPG.

Regular maintenance, especially tire inflation, is critical. Maintain the correct tire pressure as indicated on the door placard, as low pressure increases rolling resistance and hurts fuel economy. Ensure that the engine is properly tuned and that the air filter is clean. Addressing minor issues promptly can prevent them from becoming fuel-wasting problems.

Minimize idling time. Letting the engine idle consumes fuel without adding any mileage. If you anticipate stopping for more than a minute, turn off the engine. Modern engines start easily and quickly, so there’s little reason to let the car idle, particularly in traffic jams.

Consider using the Q70’s drive mode selector. If equipped, the “Eco” or “Standard” mode will optimize the engine and transmission settings for efficiency. While it might slightly reduce performance, the fuel savings can be worthwhile, especially on long trips. Sport mode will drastically lower MPG.

Lighten the load. Remove any unnecessary items from the trunk and passenger area. Extra weight forces the engine to work harder, reducing fuel efficiency. A lighter vehicle requires less energy to move, resulting in better MPG.
