How much does the 2020 INFINITI QX80 cost?

Is the 2020 INFINITI QX80 a good car?

Yes — the 2020 INFINITI QX80 earns a 5/5 user rating and a 7.33/10 expert rating. The model scores 8/10 across Performance and Form and function.

It stands out as a large luxury SUV that emphasizes comfort and a premium feel, with a powerful engine and a comfortable ride as its core strengths. The tradeoff is clear: outdated technology and poor fuel economy hold it back.

Cons: Outdated technology; poor fuel economy.

For you, that means the QX80 makes the most sense if you want a full-size luxury SUV focused on relaxed driving, a well-appointed cabin, and traditional capability rather than modern tech polish. 35.3% of listings are priced as good or great deals, so there is some room to shop selectively.

Is the 2020 INFINITI QX80 reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction.

The QX80’s appeal comes from its straightforward, truck-based durability and its emphasis on comfort over complexity. Its powertrain is described as capable of handling the SUV’s weight, and the ride is tuned to soak up road imperfections while staying level when towing.

The model also comes with a four-year/60,000-mile basic warranty and a six-year/70,000-mile powertrain warranty, which helps reduce early ownership risk. For used buyers, the bigger long-term concern is less about outright mechanical drama and more about living with an older design that can feel dated as mileage and age add up.

What should I look for when buying a used 2020 INFINITI QX80?

At 70.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm whether any prior damage was repaired properly. A pre-purchase inspection should focus on body condition, panel alignment, interior wear, and signs that the SUV’s luxury features still work as intended. Because this is a large, older luxury SUV, you’ll want to pay close attention to how it has been maintained and whether it still feels tight on the road.

Key things to evaluate:

• Trim level: The QX80 is sold in two trim levels: Luxe and Limited. The Limited adds matte silver and open-pore Ash wood trim, while the cabin overall is upscale but some trim pieces are not as refined as rivals.
• Powertrain: All QX80s use a 5.6-liter V8 with a seven-speed automatic, making 400 horsepower and 413 pound-feet of torque. Rear-wheel drive is available on Luxe, four-wheel drive is available on Luxe, and Limited comes standard with 4WD.
• Safety package: Standard equipment includes automatic emergency braking, rear cross-traffic alert, pedestrian detection, forward collision warning, rear parking sensors, a surround-view camera system, and automatic collision notification. Available upgrades include blind-spot monitoring, lane-departure warning, adaptive cruise control, distance-control assist, and lane-keep assist.
• Infotainment: Standard tech includes an 8-inch upper touch screen and a 7.0-inch lower touch screen, plus Apple CarPlay, Android Auto, navigation, satellite radio, Bluetooth, keyless entry, remote start, tri-zone climate control, a moonroof, and four USB ports. You can upgrade to two 8.0-inch displays, a rear-seat entertainment system, and a WiFi hot spot.
• Fuel efficiency: The rear-wheel drive model is rated at 14 mpg city, 20 mpg highway, and 16 mpg combined, while the four-wheel drive model is rated at 13 mpg city, 19 mpg highway, and 15 mpg combined.

Which 2020 INFINITI QX80 trim should I buy?

The 2020 INFINITI QX80 is offered in 2 trim levels: Luxe and Limited.

Here's the short version:

• Luxe: This is the trim to target if you want the best balance of price and equipment. It already gives you the V8, the dual-screen infotainment setup, Apple CarPlay, Android Auto, navigation, and the core safety tech, while still letting you choose rear-wheel drive or four-wheel drive.
• Limited: This is the more upscale choice if you want the richer cabin treatment and standard 4WD. It adds matte silver and open-pore Ash wood trim and suits you best if you want the most luxurious version without adding packages.

The safety content notes that the QX80 is an older model, so it lacks some newer driver-assistance features found in newer luxury SUVs.

Is now a good time to buy a used 2020 INFINITI QX80?

This looks like a moderate, selective buyer’s market, so you can shop with some leverage if you’re patient.

• Deal availability: 35.3% of listings are priced as good or great deals.
• Inventory: There are 666 listings available.
• Price trend: Prices have softened 13.67% compared with last year.
• Clean inventory: 70.7% of listings are accident-free.

If you find a listing below $22,756, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 INFINITI QX80's resale value?

The current average of $22,760 sits slightly below last year's $26,364.

That decline suggests the market has already adjusted downward, which can help you as a buyer but may pressure future resale if you plan to sell soon. For a future owner, the key question is whether the QX80’s luxury appeal and strong equipment list can offset its age and fuel costs in the used market.

Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.

Is the 2020 INFINITI QX80 safe?

The Infiniti QX80 earns good scores in the IIHS moderate overlap front and side crash tests.

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

Standard safety features include automatic emergency braking, rear cross-traffic alert, pedestrian detection, forward collision warning, rear parking sensors, a surround-view camera system, and automatic collision notification. You can add blind-spot monitoring, lane-departure warning, adaptive cruise control, distance-control assist, and lane-keep assist.

The main caveat is that this is an older model, so it does not offer the breadth of newer driver-assistance technology found in many newer luxury SUVs. The NHTSA notes better crashworthiness from the side than the front and a moderate rollover risk.

Should I buy a 2020 INFINITI QX80 or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 35.3% of listings are priced as good or great deals.
• At 70.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 13.67% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2020 QX80 pairs a refreshed luxury cabin with a powerful V8 and a comfortable ride.

Consider the 2019 if:

• At $21,342, the 2019 costs less than the current year's $22,760 average.
• It offers plush comfort and old-school luxury appeal.

Consider the 2021 if:

• At $29,390, the 2021 costs more than the current year's $22,760 average.
• It adds a reshuffled trim lineup and an improved Smart Rearview Mirror.

The bottom line: If you want the best mix of price, luxury, and capability, the 2020 is the sweet spot. If you’re especially price-sensitive, the 2019 is the cheaper path, while the 2021 makes sense only if you want the newer updates and are willing to pay more.
