The Big Picture: Total Five-Year Cost
The total five-year cost to own a new Infiniti QX80 varies quite a bit depending on the model year and trim level. Here’s a look at the numbers from different sources:
| Model Year / Trim | Total 5-Year Cost | 5-Year Depreciation | Out-of-Pocket Expenses |
|---|---|---|---|
| 2026 QX80 (Base) | $113,650 | $49,695 | $63,955 |
| 2026 QX80 PURE | $116,040 | $53,099 | $62,941 |
| 2025 QX80 PURE | $111,396 | $48,055 | $63,341 |
| 2025 QX80 LUXE | $123,043 | $57,067 | $65,976 |
| 2026 QX80 AUTOGRAPH | $140,104 | $69,482 | $70,622 |
It’s important to note that these figures are estimates from data providers like Kelley Blue Book and Edmunds. Actual costs will vary based on your driving habits, location, and how well you maintain the vehicle .
Breaking Down the Costs
The Depreciation Hit: Your Money’s Silent Vanishing Act
This is the single largest cost of owning a new QX80. The moment you drive it off the lot, it starts to lose value. One estimate shows a 2026 QX80 losing over $23,000 in its first year alone . After five years, the depreciation can be anywhere from $49,000 to over $69,000, meaning the car could retain only about 31% to 50% of its original value .
This is something to think about if you might want to sell or trade in the vehicle after a few years. The massive depreciation on a new luxury SUV is often why buying a used QX80 can be a much better financial move .
Fuel Costs: Filling Up a Large SUV
The QX80 is a big vehicle, and it has a big thirst for premium gasoline. The EPA estimates for the redesigned 2025 and 2026 models with the 3.5L V6 engine are about:
- 18 mpg combined for the rear-wheel-drive version
- 17 mpg combined for the all-wheel-drive version
Based on 15,000 miles a year, this translates to an estimated annual fuel cost of roughly $3,400 to $4,050 . Over five years, that’s between $15,000 and $20,000 just for gas .
Insurance Costs: Protecting Your Investment
Insuring a large luxury SUV isn’t cheap. Over a five-year period, data shows insurance costs totaling around $21,000 to $22,000 for a new model . This is a significant chunk of the “out of pocket” expenses.
However, it’s not all bad news. One insurance company suggests average rates for a QX80 can be as low as $34 a month . This huge range shows that insurance costs are highly personal and will vary based on your location, driving history, and coverage.
Maintenance and Repairs: A Surprising Bright Spot
Here’s some good news. According to CarEdge, the Infiniti QX80 has below-average maintenance and repair costs for its class. The average cost for maintenance and repairs over the first five years is about $4,117, which is nearly $1,400 less than the industry average for similar vehicles .
RepairPal also gives the QX80 a reliability score of 3.5 out of 5.0, ranking it first out of 19 full-size luxury SUVs . The average annual repair cost is about $718, compared to $1,127 for other vehicles in its class . While you should still budget for scheduled maintenance like oil changes and tire rotations, the QX80 seems to be reasonably reliable and not as expensive to fix as some of its German rivals.
New vs. Used: A Smart Way to Save
The data strongly suggests that buying a used QX80 can save you a significant amount of money. Since the car depreciates so quickly in the first few years, you can avoid the steepest part of the cost curve.
For example, the 2025 QX80 PURE, which may have a sticker price around $83,000, could be found on the used market for significantly less . Depreciation calculators show the value after just two or three years can drop by nearly half . This is why many experts recommend looking at a gently used QX80—you get the luxury and capability but at a much lower initial cost .
