2021 Infiniti QX80 MODEL OVERVIEW


  • Comfortable, luxurious interior
  • New standard active safety features
  • Good straight-line performance


  • Poor fuel economy
  • Sloppy handling
  • Low safety ratings

The QX80 is Infiniti's largest SUV, positioned above the QX50, QX55, and QX60. The current-generation QX80, which shares a platform with the Nissan Titan and Armada, initially debuted for the 2011 model year as the QX56, a nod to its standard 5.6-liter V-8. The QX80 competes against other truck-based large luxury SUVs including the Lexus LX, Cadillac Escalade, and Lincoln Navigator.

What's New

  • New trim lineup: Luxe, Premium Select, and Sensory
  • Active safety features added as standard

What We Think

Although we were impressed with the QX80 after our year-long loan back in 2011, in the modern context, it's not competitive. When it faces off against other full-size three-row luxury SUVs, the QX80 is one of our lowest-ranked contenders, due in part to its poor fuel economy and cramped third-row seating.

The QX80 has seen more than a few updates since its introduction for 2011, including facelifts for 2014 and 2018. We liked the new styling of the latter refresh, but it retained the sloppy handling and uncontrolled body roll of earlier versions. At least the standard V-8 offsets inefficiency with strong performance. Most of its strengths lie in the QX80's luxuriously appointed, impressively comfortable interior. The addition of standard active safety features for 2021 is much appreciated.

Even if the dual-screen infotainment system that debuted last year works better than in similar setups in other Infinitis, that wouldn't make the QX80 a better choice than newer competitors. The handling, fuel economy, and technology on offer in those cars emphasize just how long this lumbering beast has been around. Hopefully a full redesign comes soon.

Performance and Fuel Economy

Regardless of trim, every QX80 features a naturally aspirated 5.6-liter V-8 under its hood. The old-school engine develops 400 hp and 413 lb-ft of torque that, with help from a seven-speed automatic, can help the flagship Infiniti reach 60 mph in 6.3 seconds. Although RWD is standard, 4WD is optional on all trims. Thanks to the standard V-8 combined with the QX80's colossal mass, fuel economy is unimpressive. EPA ratings read 13-14/19-20 mpg city/highway.


The QX80 receives a disappointing four-star overall safety rating from the NHTSA. It earns a five-star rating for side crash safety, but a three-star frontal crash scores and a three-star rollover rating are cause for some concern.

As for driver-assist active safety features, Infiniti is making some of its previously optional equipment standard for 2021. Blind spot intervention, lane keep assist, rear seat reminder, and adaptive cruise control are now included on all QX80s. Automatic emergency braking continues to be standard.

Cargo Space and Interior Room

You buy the big SUV because it's more spacious and can carry more cargo, right? The QX80 offers 16.6 cubic feet of cargo volume behind the standard third row, 49.6 with the third row folded down, and 95.1 cubes with both rows of rear seating folded. Compare that to the standard Lincoln Navigator's 19.3, 57.5, and 103.3 cubic feet of space.

Seating capacity in the Infiniti is rated at seven with 39.6 inches of legroom up front, 41.0 inches in the second row, and 28.8 inches in the way-back. You'll find more room in the standard Navigator, with 43.9, 41.1, and 42.3 inches of space.


The QX80 gained a refreshed version of Infiniti's InTouch infotainment technology for the 2020 model year. It features dual touchscreens, an 8.0-inch display up top and a 7.0-inch display down below. Apple CarPlay, Android Auto, and integrated navigation are all standard. For you audiophiles out there, 13-speaker audio is standard, and a 17-speaker setup is included on higher trims.
