The 2016 Infiniti QX70 RWD 3.7L gets 19 MPG combined. It’s not stellar, nor is it disastrous. Frankly, it’s largely irrelevant to the buyers drawn to this car. The QX70 isn’t about maximizing efficiency; it’s about a specific design, a powerful V6, and a driving experience that prioritizes driver engagement. This is a crossover for those who appreciate design and performance and aren’t particularly concerned with fuel costs. The QX70 buyer wants a statement, and they’re willing to pay for it at the pump.

City and highway performance

The EPA estimates 17 MPG in the city and 24 MPG on the highway for the rear-wheel drive QX70 with the 3.7L V6. These numbers reflect stop-and-go traffic and sustained highway cruising. The city figure is hampered by the vehicle’s weight and the engine’s eagerness to rev. The highway estimate benefits from the seven-speed automatic transmission, which allows the engine to settle into a more relaxed state at higher speeds. Aggressive acceleration or higher speeds will quickly diminish the highway fuel economy. The engine requires premium fuel, adding to running costs.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Infiniti QX70 RWD 3.7L is $3,050. This figure is based on driving 15,000 miles per year and national average fuel prices. Keep in mind that this is an estimate, and your actual fuel costs will vary depending on your driving habits, location, and the specific price of gasoline in your area. Stop-and-go driving, frequent hard acceleration, and consistent use of premium fuel will all increase your annual fuel expenses beyond this estimate. Consider this figure a benchmark for comparison against other vehicles, and understand that it represents a best-case scenario for the average driver.

Real-world expectations

While the EPA provides standardized testing, real-world fuel economy can vary significantly. Drivers who prioritize smooth, gradual acceleration and consistent speeds are more likely to approach the EPA estimates. However, the QX70’s engaging driving encourages a more spirited driving style, impacting fuel consumption. Climate control settings, tire pressures, and vehicle maintenance can also affect your overall efficiency.

How it compares

Compared to its competitors, the 2016 Infiniti QX70’s fuel economy lags behind some of the more efficient options. For example, the Acura MDX (FWD) achieves 20 MPG city and 28 MPG highway, while the Lexus RX 350 boasts 20 MPG city and 27 MPG highway. Even within the Infiniti family, you can find better fuel economy; check out all Infiniti fuel economy data for a broader picture. The BMW X5 sDrive35i manages 19 MPG city and 25 MPG highway, showing that some competitors can extract better mileage from similarly sized engines. This comparison matters to some shoppers, but those who value the QX70’s distinctive styling and driving character may be willing to sacrifice some fuel efficiency.

Tips to maximize efficiency

Use the QX70’s cruise control on the highway to maintain a consistent speed and avoid unnecessary acceleration, which can significantly impact fuel economy. Anticipate traffic flow and avoid abrupt braking or acceleration; that smooth driving helps minimize excessive fuel consumption.

Ensure that your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, requiring the engine to work harder and consuming more fuel. Check your tire pressure regularly, especially during temperature changes.

Reduce unnecessary weight in the vehicle. Excess cargo adds load to the engine, forcing it to burn more fuel. Remove items from the trunk that are not essential for daily use.

While the QX70’s V6 engine is responsive and encourages spirited driving, avoid excessive idling. If you anticipate being stationary for more than a minute, turn off the engine to conserve fuel. Doing so will positively influence MPG over time.
