How much does the 2021 INFINITI QX80 cost?

Prices have softened 11.71% compared to this time last year, making it a favorable time to shop this model year.

There are 499 listings available, which gives you a meaningful amount of inventory to compare across trims and conditions.

If you find a listing below $29,906.36, 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 looks strongest if you value comfort and traditional luxury more than modern efficiency or sharp handling. Owners repeatedly praise the luxurious and comfortable ride, the smooth driving experience, and the refined interior, while also appreciating the improved features. The overview frames it as a full-size luxury SUV for you if you want space, premium materials, and a more truck-like foundation.

The trade-offs are just as clear: the expert notes call out poor fuel economy and poor handling, and owners also mention limited entertainment content in lower trims and some cosmetic issues in certain vehicles. The model scores 8/10 across Look and feel and Performance.

With 32.7% of listings marked as good or great deals, you have some room to shop selectively if you’re focused on value.

Is the 2021 INFINITI QX80 reliable?

The 2021 INFINITI QX80 is built around a familiar, body-on-frame formula, which can be appealing if you want a more traditional SUV setup. Owners describe it as reliable-feeling in the sense that it delivers a smooth, comfortable, and refined driving experience, and they also point to its luxurious interior and improved features as positives.

The expert notes add that the V8 powertrain is responsive and that the SUV’s independent suspension helps deliver a very comfortable ride. Infiniti also includes a four-year, 60,000-mile basic warranty and a six-year, 70,000-mile powertrain warranty.

For used buyers, the main long-term ownership risk is that a large, V8-powered luxury SUV can become expensive to live with if prior maintenance has been deferred.

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

At 73.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle-history report and then prioritize a pre-purchase inspection, especially if the listing price looks unusually attractive. Focus on overall condition, signs of cosmetic wear, and whether the vehicle’s equipment and features work as expected. Because this is a large luxury SUV, you’ll also want to pay close attention to how it drives at low speeds and over bumps.

Key things to evaluate:

• Trim level: The base Luxe trim rides on 20-inch wheels, while Premium Select and Sensory models get 22-inch wheels. The interior uses leather upholstery, but Sensory models add perforated semi-aniline leather.
• 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. The engine makes 400 horsepower and 413 pound-feet of torque.
• 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.
• Infotainment: The standard setup uses 8.0-inch upper and 7.0-inch lower touchscreens, with Apple CarPlay, Android Auto, navigation, and a built-in WiFi hotspot. Wireless smartphone integration is not listed here, and the interface is described as cumbersome.
• Fuel efficiency: EPA ratings are 16 mpg combined, 14 mpg city, and 20 mpg highway with rear-wheel drive, or 15 mpg combined, 13 mpg city, and 19 mpg highway 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:

• Base trim: Luxe gives you the core QX80 experience, but it rides on 20-inch wheels and misses the added visual presence of the higher trims.
• Sweet-spot trim: Premium Select is the best middle ground if you want the upgraded 22-inch wheels without going all the way to the top trim.
• Premium/top trim: Sensory is the most appealing choice if you want the richest cabin, with perforated semi-aniline leather and standard Hydraulic Body Motion Control.
• Off-road trim: None of the trims is positioned as a dedicated off-road variant for daily use.

Standard safety equipment is generous 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 carefully without expecting every listing to be a bargain.

• Deal availability: 32.7% of listings are priced as good or great deals.
• Inventory: There are 499 listings available.
• Price trend: Prices have softened 11.71% compared with last year.
• Clean inventory: 73.9% of listings are accident-free.

If you find a listing below $29,906.36, 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 $29,907 sits slightly below last year's $33,872.

That price movement suggests the QX80 has already absorbed a meaningful amount of depreciation, which can help you as a buyer today. If you plan to sell later, though, the same trend means you should expect resale values to remain sensitive to mileage, condition, and equipment. Well-kept examples with strong history and desirable features should hold up better than neglected ones.

Is the 2021 INFINITI QX80 safe?

The National Highway Traffic Safety Administration (NHTSA) gave the 2021 Infiniti QX80 a four-star overall safety rating, with five-star ratings for side crash tests, four-star ratings for frontal crash tests, and a three-star rollover rating.

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

Standard safety features include 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 is a strong standard list for the class, and Infiniti makes it standard equipment rather than reserving it for higher trims.

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:

• 32.7% of listings are priced as good or great deals.
• At 73.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 11.71% compared with last year.
• It adds a refreshed mirror and a reshuffled trim lineup.

Consider the 2020 if:

• At $23,215, the 2020 costs less than the current year's $29,907 average.
• It emphasizes comfort and capability with a more luxurious feel.

Consider the 2022 if:

• At $37,347, the 2022 costs more than the current year's $29,907 average.
• It adds a larger 12.3-inch display and wireless Apple CarPlay.

The bottom line: The 2021 is the right path if you want the current-year pricing advantage and can live with its older tech and truck-like character. If you are especially price-sensitive, the 2020 is the value play; if you want a more modern cabin, the 2022 is the better upgrade.
