How much does the 2021 INFINITI QX80 cost?

If you find a listing below $29,566.04, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2021 INFINITI QX80 a good car?

With a 3.8/5 user rating and a 7.33/10 expert rating, the 2021 INFINITI QX80 lands in appealing territory if you value comfort and traditional luxury more than modern polish.

Owners repeatedly praise its comfortable ride, smooth driving experience, and refined interior, which lines up with its full-size luxury-SUV mission. The expert test drive also backs up the QX80’s spaciousness and premium interior materials, while the overview frames it as a fit for buyers who want upscale comfort with a rugged, truck-like foundation.

The trade-offs are just as clear: the expert notes point to poor handling and poor fuel economy, and owners mention disappointment with limited entertainment content in lower trims. That makes the QX80 a better match if you want a relaxed, roomy cruiser than if you want sharp road manners or the latest tech.

The model scores 8/10 across Look and feel and Performance.

With 33.5% of listings marked as good or great deals, you have some room to shop selectively.

Is the 2021 INFINITI QX80 reliable?

The 2021 INFINITI QX80 is built around a body-on-frame layout and a proven V8 powertrain, which supports its long-haul, truck-based character.

Owners describe it as reliable, comfortable, and smooth, with several comments pointing to a refined cabin and a generally trouble-free feel. The expert notes also emphasize its durable, old-school construction and dependable highway behavior, which should reassure you if you want a large SUV that feels built for long-term use.

Infiniti’s warranty coverage includes a four-year, 60,000-mile basic warranty and a six-year, 70,000-mile powertrain warranty, which adds some ownership protection. For used buyers, the main long-term risk is that age, complexity, and fuel costs can make upkeep more expensive than the driving experience suggests.

What should I look for when buying a used 2021 INFINITI QX80?

Accident-free inventory is solid at 75.9% — always verify the vehicle history report.

You should start with the history report, then prioritize a close inspection of the cabin, exterior cosmetics, and any signs of prior damage or heavy wear. Because this SUV is large and luxury-focused, condition matters a lot: small issues can be more noticeable, and neglected examples may cost more to refresh.

Key things to evaluate:

• Trim level: The base Luxe trim rides on 20-inch wheels, while Premium Select and Sensory move up to 22-inch wheels. The interior uses standard leather upholstery, and Sensory adds perforated semi-aniline leather, so lower trims are the ones most likely to feel less richly appointed.
• Powertrain: Every model uses a 5.6-liter V8 with a seven-speed automatic transmission. Rear-wheel drive is standard, and four-wheel drive is available for buyers who want the added traction and low-range capability.
• Safety package: Standard equipment includes adaptive cruise control, blind-spot monitoring, lane-departure warning, lane-keep assist, forward collision warning, automatic emergency braking with pedestrian detection, and Backup Collision Intervention. These features are standard rather than optional, which is a useful advantage on lower trims.
• Infotainment: You get dual touchscreens measuring 8.0 inches up top and 7.0 inches below, plus Apple CarPlay, Android Auto, a built-in WiFi hotspot, navigation, Bluetooth, SiriusXM satellite radio, and a 13-speaker Bose audio system. The interface is not especially easy to use, so test it carefully before you buy.
• Fuel efficiency: EPA ratings are 16 mpg combined with rear-wheel drive and 15 mpg combined with four-wheel drive.

Which 2021 INFINITI QX80 trim should I buy?

The 2021 INFINITI QX80 is offered in 3 trim levels: Luxe, Premium Select, Sensory.

Here's the short version:

• Luxe: This is the entry point, but it still gives you the core QX80 experience with standard leather upholstery, 20-inch wheels, and the full suite of standard driver-assistance features. It makes sense if you want the lowest starting price and are comfortable skipping the richer wheel and interior upgrades.
• Premium Select: This trim adds a more upscale look with 22-inch wheels and sits in the middle of the lineup, making it the best-value choice if you want a stronger luxury impression without jumping to the top trim.
• Sensory: This is the most luxurious version, with perforated semi-aniline leather, 22-inch wheels, and the most premium presentation in the lineup. It suits you best if you want the richest cabin and don’t mind paying for it.

The safety package is standard across the lineup, so you do not need to move up a trim just to get the core driver-assistance features.

Is now a good time to buy a used 2021 INFINITI QX80?

This looks like a moderate, selective buyer’s market, so you can shop patiently but still move quickly on the right listing.

• Deal availability: 33.5% of listings are priced as good or great deals.
• Inventory: There are 493 listings available.
• Price trend: Prices have softened 12.19% compared with last year.
• Clean inventory: 75.9% of listings are accident-free.

If you find a listing below $29,566.04, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 INFINITI QX80's resale value?

The current average of $29,557 sits slightly below last year's $33,661.

That decline suggests the QX80 has softened in the market, which can help you buy at a better entry price today. For a future seller, that also means resale upside may be limited unless your vehicle is especially clean, well-equipped, and well maintained.

If you plan to sell later, condition and mileage will matter a lot because buyers in this segment are sensitive to value. A well-kept example should hold up better than a neglected one, but the broader trend still points to a softer resale environment.

Is the 2021 INFINITI QX80 safe?

The 2021 INFINITI QX80 earns a four-star overall rating from NHTSA, with five-star ratings in side crash tests, four-star ratings in frontal crash tests, and a three-star rollover rating.

It earns a 7/10 safety score from our experts.

Standard safety equipment includes adaptive cruise control, blind-spot monitoring, lane-departure warning, lane-keep assist, forward collision warning, automatic emergency braking with pedestrian detection, and Backup Collision Intervention. That’s a strong standard list for the class, especially because Infiniti makes these features standard rather than reserving them for higher trims.

The main caveat is the three-star rollover rating, which is worth keeping in mind if safety is a top priority for you.

Should I buy a 2021 INFINITI QX80 or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 33.5% of listings are priced as good or great deals.
• Accident-free inventory is solid at 75.9% — always verify the vehicle history report.
• Price trend: Prices have softened 12.19% compared with last year.
• It keeps the old-school body-on-frame character while adding small updates and standard safety features.

Consider the 2020 if:

• At $22,763, the 2020 costs less than the current year's $29,557 average.
• It emphasizes comfort and capability with a more luxurious feel than the Armada.

Consider the 2022 if:

• At $36,526, the 2022 costs more than the current year's $29,557 average.
• It adds a larger 12.3-inch display and wireless Apple CarPlay for a more modern cabin.

The bottom line: If you want the best balance of price, inventory, and standard equipment, the 2021 is the strongest all-around pick. If your budget is tighter, the 2020 gives you the core QX80 experience for less. If you want newer tech and are willing to pay more, the 2022 is the better upgrade path.
