20 MPG combined is not the reason anyone buys a 2019 Infiniti Q70 AWD with the 3.7L V6. It’s a consequence, a number accepted by drivers who prioritize smooth, responsive power and the confidence of all-wheel drive in a well-appointed, traditionally styled luxury sedan. This Q70 isn’t about squeezing every last mile from a gallon of premium fuel; it’s about a specific blend of luxury, performance, and timeless design, a blend that commands a certain price at the pump.

City and highway performance

The EPA rates the 2019 Infiniti Q70 AWD 3.7L at 18 MPG in the city and 24 MPG on the highway. These figures reflect the nature of the naturally aspirated 3.7L V6 and the demands placed upon it in different driving environments. City driving, with its frequent stops and starts, inherently taxes fuel efficiency. The Q70’s weight also plays a role here, as more energy is required to get the car moving from a standstill. On the open highway, the Q70’s seven-speed automatic transmission can settle into a more efficient gear, allowing the engine to cruise comfortably, but that doesn’t translate to best in class fuel efficiency. Buyers who are concerned with fuel economy should consult all Infiniti fuel economy data before purchasing this vehicle.

Annual fuel cost

The estimated annual fuel cost for the 2019 Infiniti Q70 AWD 3.7L is $2,900, according to the EPA. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s a good point of reference, but remember that individual fuel costs can vary greatly based on driving habits, local fuel prices, and the percentage of city versus highway driving. Aggressive acceleration, frequent idling, and consistent short trips will all inflate that $2,900 figure significantly.

Real-world expectations

While the EPA provides a standardized testing method, real-world MPG often differs. Q70 drivers who enjoy the engine’s responsiveness and the all-wheel-drive system’s added grip in inclement weather may find themselves closer to the 18 MPG city figure than the 24 MPG highway estimate, especially if their commute involves heavy traffic. Conservative drivers with predominantly highway miles can likely achieve numbers closer to the EPA’s highway estimate, but exceeding it consistently would require conscious effort and careful throttle management. If fuel economy is a primary concern, careful data monitoring on a trip-by-trip basis is recommended to understand fuel consumption patterns.

How it compares

Compared to its competitors, the 2019 Infiniti Q70 AWD 3.7L’s fuel economy sits squarely in the middle of the pack. For example, the Acura TLX SH-AWD with the 3.5L V6 achieves 21 MPG combined, a slight advantage. A BMW 540i xDrive, with its turbocharged inline-six, boasts a more impressive 25 MPG combined. An Audi A6 3.0T Quattro also manages 25 MPG combined. The Genesis G80 3.3T AWD performs similarly to the Q70, around 20 MPG combined. This comparison is critical for buyers weighing power and luxury against the cost of fuel. Many consider Q70 MPG across all years to better understand fuel economy trends for this model.

Tips to maximize efficiency

The Q70’s 3.7L V6 isn’t the most efficient engine in its class, but there are steps owners can take to reduce its thirst. Avoid aggressive acceleration and braking, as these actions consume a disproportionate amount of fuel. Treat the throttle gently, and anticipate traffic flow to minimize sudden changes in speed.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly, ideally every week, and inflate them to the manufacturer’s recommended pressure found on the doorjamb sticker.

Regular maintenance is also key to maximizing fuel efficiency. A well-maintained engine runs more efficiently. Ensure the engine air filter is clean, spark plugs are in good condition, and that the car receives scheduled oil changes.

Minimize unnecessary weight in the vehicle. Excess cargo adds to the vehicle’s overall weight, which, as noted above, reduces fuel economy. Remove any items you don’t need from the trunk and backseat to lighten the load.

Consider using cruise control on long highway stretches. Maintaining a constant speed can help improve fuel efficiency compared to fluctuating your speed manually. However, use cruise control judiciously, as it can sometimes be less efficient in hilly terrain than a driver who anticipates the inclines and declines.
