2-Line Blurb

140-Character Blurb

The 2026 Infiniti QX80 is a tech-forward, capable full-size luxury SUV with classy style and plenty of power.

Cons

<ul>
<li>Still not as large as some large luxury SUVs</li>
</ul>

Power, Ride, and Handling

Driving Impressions

Under the hood, you’ll find 450 horsepower and 516 lb-ft of torque from a twin-turbocharged 3.5-liter V6 engine. That’s 50 hp and 103 lb-ft more than the previous-gen QX80. It’s a serious bump, enough to put the QX80 shoulder-to-shoulder with Navigator and Escalade. There’s a hint of turbo lag, but uphill or on the highway, it never feels short on muscle.
Steering? Nicely weighted, especially in Sport mode, which adds a little heft. Prefer to let the car do the work? ProPilot 2.1 brings partial self-driving capability.
Ride quality gets a big assist from the adaptive suspension (standard on Luxe and up), which smooths out the harshness you might expect from 22-inch wheels. It’s not quite GLS-level sophistication, but body roll stays well in check.
Fuel Economy
The 2026 QX80 gets 18 mpg combined with rear-wheel drive (RWD), or 17 mpg combined with 4-wheel drive (4WD). That’s a couple mpg better than the V8 in the old QX80. For context, the GLS 450 4Matic does 21 mpg, but with just 362 hp. The Cadillac Escalade scores combined ratings of 17 mpg with rear-wheel drive, or 16 mpg with 4-wheel drive.

Balanced Proportions

Exterior

The QX80&#8217;s proportions are spot-on, and details like the bamboo-inspired grille, flush door handles, and full-width LED tail lamps make it stand out. Higher trims even greet you with a light show when you approach.

FAQs

Our Favorite Features and Tech

Favorite Features

Google built-in 
With Google built-in, voice commands feel more natural, navigation runs through Google Maps, and your favorite apps are right there on the big screen. And yes, Apple iPhone users are still covered with full compatibility.
Klipsch Audio 
Klipsch might not be a household name in cars, but in home audio circles, it’s legendary. Every QX80 gets a Klipsch system: either 14 speakers and 600 watts in the two lower trims, or 24 speakers and 1,200 watts in the upper models. It’s the kind of sound that turns a commute into a concert.
Wide Front View 
Parking lot blind spots? Narrow alleys? The Wide Front View camera has your back, or rather, your front. Covering 170 degrees, it lets you see what’s coming when you’re creeping out of a tight space or peeking around a corner.
Invisible Hood View 
Ever wish you could see through the hood? This feature comes close. By stitching together images from multiple cameras, it gives you a virtual look at what’s hiding right in front, whether it’s curbs, car wash tracks, or other hazards.
Biometric Cooling 
An infrared sensor above the second row monitors body temperature and tells the climate system where to send cooler air. No more “too hot back here” complaints, just quiet, personalized comfort.
Journey Diary 
Journey Diary captures images and video from the forward-facing cameras, and, if equipped, the in-cabin camera, so you can relive the adventure or share it on social media. It’s like having a built-in photographer and videographer for your QX80.

More Space and Elegance

Interior

When you step inside, it’s clear Infiniti aimed for elegance. Two 14.3-inch displays dominate the dash, with a 9-inch climate screen below. A head-up display joins the party at Luxe trim.
Seating is for seven or eight, with captain’s chairs in the second row if you go with seven. Front seats? Wide and supremely comfortable. Outward visibility? Excellent.
The Autograph trim is pure indulgence, with soft-touch everything, fine materials, and massaging seats in both rows. Yes, second-row passengers get the spa treatment too.
Access to the third row is easy, even with child seats installed. Back there, shorter passengers will be happiest, but they still get USB-C ports (eight total in the cabin), vents, and optional heating.
The QX80’s cargo space is considerably larger than in the previous-generation model, with 20.4 cubic feet available behind the third row, 56.3 cubic feet behind the second row, and a maximum of 97.1 cubic feet behind the first row.
For comparison, the GLS maxes out at 84.7 cubic feet, and the BMW X7 offers 90.4 cubic feet. That means the QX80 is one of the larger luxury SUVs around, although it’s still smaller than the likes of the Escalade and Navigator, both of which offer more than 100 cubic feet of space.
If we have one gripe with the QX80&#8217;s cabin, it’s the button-style transmission selector. It frees up console space for storage and wireless charging, but we’d prefer a traditional shifter. On the plus side, you can specify a chilled compartment big enough for a six-pack.

KBB Editors' Overview

All-new last year, the 2026 Infiniti QX80 continues to make a statement. This full-size luxury SUV brings commanding presence, cutting-edge tech, and a cabin that feels like a private jet lounge. This is also the first Infiniti model to wear a six-figure price tag. The old QX80 was the bargain in this class, but the new one aims for the top shelf, adding everything buyers expect, like premium audio, exquisite materials, and even a climate system that reads body heat.
We’ve logged hundreds of hours driving and evaluating this generation of <a href="https://www.kbb.com/suv/best-luxury-full-size-suvs/">full-size luxury SUVs</a>, including the Infiniti QX80.

Optional Equipment

Pricing - Dynamic

Pricing - Static

The high-spec Sensory trim has long been the go-to version of the QX80, but with the redesigned model, the Sensory trim is no more. Instead, we can see plenty of buyers choosing the midrange Luxe trim with all-wheel drive (AWD), landing around $95,000.
The QX80 is priced in the same league as the Lincoln Navigator, Cadillac Escalade, Mercedes-Benz GLS, and BMW X7. The Lexus LX and Jeep Grand Wagoneer are priced a little higher. Some rivals also offer extended-length versions for extra cargo space.
Before you buy a new large luxury SUV, check KBB’s Fair Purchase Price. The old QX80 lagged slightly in resale value, but this redesign should improve things, meaning more money back when you trade in.

Under the Hood

The new QX80 packs serious muscle in the form of a twin-turbocharged 3.5-liter V6 delivering 450 hp and 516 lb-ft of torque. A smooth-shifting 9-speed automatic handles the power distribution. Rear-wheel drive is standard on the two lower trims, while all-wheel drive is optional there and standard on the top two trims. Need to tow? The QX80 is rated for a hefty 8,500 pounds.
<h3>4-Year/60,000-Mile Warranty</h3>
Infiniti’s coverage beats the norm. Every 2026 QX80 comes with four years or 60,000 miles of new-vehicle warranty (whichever happens first), plus unlimited-mile roadside assistance. The powertrain is covered for six years or 70,000 miles, and you also get three years of complimentary scheduled maintenance, no mileage cap.
<h3>Safety</h3>
The 2026 Infiniti QX80 hasn’t yet been crash-tested by the relevant authorities, but the nearly identical 2025 model earned a Top Safety Pick+ rating from the Insurance Institute for Highway Safety (<a href="https://www.iihs.org/" target="_blank" rel="noopener">IIHS</a>), the body’s highest rating. In addition to its crash test performance, every QX80 comes standard with advanced safety tech like forward collision warning with automatic braking and pedestrian detection, trailer blind-spot warning, a 360-degree camera system, and much more.

What's new for 2026

The QX80 was all-new for the 2025 model year, but there are still new features on the table for 2026, including a new Sport grade that features dark-themed exterior styling, including a black grille, dark chrome trim, and other black exterior details, plus unique 22-inch wheels. Also new for 2026 is a Dusk Blue interior theme with dark matte chrome accents, open-pore wood trim, and other detail upgrades.
