18 MPG combined is what you get with a 2017 Infiniti QX70 AWD with the 3.7L V6. Frankly, if you buy this car you aren’t prioritizing fuel efficiency. People choose it for its style, engaging driving, and luxury, things that often mean you’ll spend more at the pump. This crossover is for those who want aesthetics and a connected driving experience over saving gas, and they’re okay with that trade-off.

City and highway performance

The QX70’s official EPA estimates show differences between city and highway driving. Expect 16 MPG in the city because the engine works harder in stop-and-go traffic. You’ll get 22 MPG on the highway. Consistent speeds let the engine operate more efficiently on the highway, and the 7-speed automatic transmission can lock up the torque converter to improve highway fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 Infiniti QX70 AWD at $3,200. This is based on driving 15,000 miles per year and assumes national average fuel prices. Your actual fuel costs depend on your driving, where you live, and the price of gasoline.

Real-world expectations

EPA estimates are a baseline, but real-world MPG often varies. Aggressive driving, short trips, and heavy loads can reduce fuel economy. QX70 owners who like fast acceleration and regularly use the all-wheel-drive system might see numbers closer to the city estimate, even when doing both city and highway driving. However, people who drive gently and mainly on the highway might see numbers close to or even slightly above the 22 MPG highway rating. Check out QX70 MPG across all years to learn more.

How it compares

The QX70’s fuel economy is lower than some of its competitors. A 2017 Acura MDX SH-AWD gets 21 MPG combined. A 2017 Lexus RX 350 AWD gets 22 MPG combined. The BMW X5 xDrive35i, which has more power, gets around 20 MPG combined. These comparisons are important. For buyers who are comparing vehicles, the QX70 emphasizes sporty driving and styling. For drivers who want to review all Infiniti fuel economy data, the QX70 is near the bottom of the list.

Tips to maximize efficiency

Accelerate gently. The QX70’s 3.7L V6 is strong, but don’t push the gas pedal all the way down every time. Smooth and gradual acceleration will save fuel, especially in the city. Watch traffic and time your driving to avoid unnecessary braking and acceleration.

Keep your tires properly inflated. Underinflated tires increase rolling resistance, which lowers fuel economy. Check your tires regularly and inflate them to the manufacturer’s specifications, which you can find on a sticker inside the driver’s side door.

Don’t idle for too long. Letting the engine idle for too long wastes fuel. Turn off the engine if you’re stopped for more than a minute. Modern engines start quickly, so it’s easy to do.

Use cruise control on the highway. Maintaining a constant speed can improve fuel economy on long highway drives. Watch the terrain and traffic conditions though. On hilly roads, cruise control might cause the transmission to downshift often, which reduces fuel savings.

Reduce air drag. Remove unnecessary cargo from the roof rack because this increases air drag. Make sure the vehicle is properly aligned, as misaligned wheels can also increase rolling resistance.
