2022 Infiniti QX80 2WD 5.6L: Understanding Its Fuel Economy

16 MPG combined is the figure to expect from the 2022 Infiniti QX80 2WD. This isn’t a vehicle designed for hypermilers; it’s a large, body-on-frame SUV built for comfortable passenger hauling, occasional towing, and a commanding presence. Buyers in this segment typically prioritize space, luxury features and capability over outright fuel efficiency, understanding that these attributes mean you’ll spend more at the gas pump. They’re looking for a reliable, spacious vehicle to transport their families and belongings in style, and they accept that comes at a cost.

City and highway performance

The EPA estimates the 2022 Infiniti QX80 2WD at 14 MPG in the city and 20 MPG on the highway. The lower city figure is unsurprising given the vehicle’s weight and stop-and-go urban driving, which strains any large displacement engine. The highway figure of 20 MPG is achievable with mindful driving, but aggressive acceleration or sustained high speeds will quickly diminish it. The combination of its 5.6-liter V8 engine and seven-speed automatic transmission are tuned more for smooth power delivery than for saving fuel.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2022 Infiniti QX80 2WD is $3,600. This figure is calculated based on driving 15,000 miles per year, using a mix of city and highway driving, and assumes national average fuel prices. Your actual fuel costs will vary depending on your driving habits and the price of gasoline in your area. This number provides a benchmark to compare the QX80’s operating expenses to other vehicles, but remember that it’s an average, not a guarantee. It’s a factor to consider for those mindful of running costs. To most QX80 buyers, this is the price of owning a large, luxurious SUV.

Real-world expectations

While the EPA numbers are a useful guide, real-world fuel economy often differs. Driving style, terrain, and environmental conditions all play a significant role. Expect the QX80’s real-world MPG to fluctuate, potentially dipping below the EPA estimates in heavy traffic or when towing. Maintaining proper tire inflation and keeping up with scheduled maintenance can help get the best possible fuel economy.

How it compares

The Infiniti QX80’s fuel economy is what you’d expect. The Cadillac Escalade with its 6.2L V8 achieves a similar 14 MPG city and 19 MPG highway. A similarly equipped Lincoln Navigator is slightly better in some tests, but not by much. Even the Lexus LX 600, known for its reliability, only manages around 17 MPG combined. Those drawn to the QX80 aren’t as concerned about squeezing every last mile out of a gallon as they are with overall comfort, capability, and value compared to its competition. If fuel economy is a primary concern, buyers might consider SUVs with smaller engines or hybrid powertrains, even if it means sacrificing some of the QX80’s other features. You can also research QX80 MPG across all years to see if older models offer better economy.

Tips to maximize efficiency

Avoid aggressive acceleration and braking, since The QX80’s powerful engine can quickly burn through fuel if you’re consistently heavy on the throttle. Maintain a steady speed and anticipate traffic flow to minimize the need for sudden stops.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Check your tire pressure regularly and inflate them to the recommended level, often found on a sticker inside the driver’s side door.

Reduce unnecessary weight. Hauling extra cargo in the QX80 adds weight, which reduces fuel economy so remove any items you don’t need to carry around regularly, especially heavy objects.

Consider using cruise control on the highway. Maintaining a consistent speed can help improve fuel economy on long trips. Be mindful of traffic conditions and avoid using cruise control in hilly terrain, as the transmission may downshift frequently, negating any potential fuel savings.
