Read about the new QX80 »

Infiniti last redesigned the QX80 for the 2011 model year, back when this model was called the QX56. For 2014, Infiniti renamed the QX56 to QX80, and it gave the SUV refreshed exterior and interior styling for 2015. Neither the 2016 nor 2017 model saw any big updates. For the 2018 model year, Infiniti again refreshed the QX80’s interior and exterior styling. If the new look isn’t important to you, then you might want to consider an older model.

2018 Infiniti QX80 Versus the Competition

Which Is Better: 2018 Infiniti QX80 or 2018 Nissan Armada?

The 2018 Nissan Armada is essentially the nonluxury version of the QX80. Both vehicles have similarly sized cargo holds, spacious first and second rows, cramped third-row seating, similar features lists, and subpar gas mileage. Both are also body-on-frame SUVs that deliver comfortable and composed rides. The QX80 is more upscale inside, but the Armada has a better predicted reliability rating. On average, the Nissan Armada costs considerably less to buy. If you can forgo the Infiniti’s extra luxury items, the Nissan is the better pick.

Which Is Better: 2018 Infiniti QX80 or 2018 Cadillac Escalade?

The 2018 Cadillac Escalade ranks with the QX80 at the back of the class. Its V8 engine produces 20 more horsepower, and it has slightly better gas mileage than the Infiniti. It also has standard Apple CarPlay and Android Auto, neither of which is available in the QX80. On the other hand, the Infiniti has a gentler ride and an easier-to-use infotainment system. It’s likely to save you money, too. The Cadillac Escalade costs much more to buy than a similarly equipped Infiniti QX80, on average. Choosing between these two SUVs is a matter of preference.

Which Is Better: 2018 Infiniti QX80 or 2018 Lincoln Navigator?

The redesigned 2018 Lincoln Navigator is one of the best luxury large SUVs you can buy. It has a cavernous cargo hold, a blissful ride, a long features list, high-end cabin materials, and lower select ownership costs. Though it lacks a V8 engine, the Navigator’s twin-turbo V6 makes 50 more horsepower than the QX80’s engine. The Lincoln is the better SUV overall.

2018 QX80 Performance

How Does the 2018 QX80 Drive?

Despite its bulk, the QX80 accelerates quickly. Its V8 engine proves more than capable when it comes to scooting uphill or cruising on the highway, and the automatic transmission makes timely shifts.

Most shoppers expect a luxury SUV to be comfortable, and the QX80 delivers. Its suspension effortlessly soaks up road flaws, and it has composed handling that may come as a surprise to some. Admittedly, it can be tough to maneuver in tighter areas, but the available Hydraulic Body Motion Control helps this full-size SUV tackle corners and turns with composure.

  • Base engine: 5.6-liter V8 with 400-horsepower and 413 pound-feet of torque
  • Drivetrain: standard rear-wheel drive; available four-wheel drive
  • Transmission: seven-speed automatic
Does the 2018 QX80 Get Good Gas Mileage?

Full-size SUVs don’t tend to earn great fuel economy estimates, but this Infiniti fares worse than most.  

  • RWD: 14/20 mpg city/highway
  • 4WD: 13/19 mpg
2018 Infiniti QX80 Towing Capacity

When properly equipped, the QX80 can tow up to 8,500 pounds.
