The Infiniti QX80 underwent one of the most significant changes in the model’s history when the redesigned generation arrived for the 2025 model year. The basic mission remained familiar: a large three-row luxury SUV with strong towing ability and commanding road presence. Nearly everything used to accomplish that mission changed, including the engine, transmission, suspension technology, cabin displays and driver-assistance features.
For shoppers, the comparison is not simply new versus old. A well-maintained previous-generation QX80 may offer proven mechanical familiarity and a much lower used price. The new generation provides more power, a more contemporary interior and technology that better matches current luxury competitors. The right choice depends on budget, tolerance for complexity, desired features and whether traditional V8 character matters.
The Biggest Mechanical Change
The previous QX80 used a 5.6-liter naturally aspirated V8 rated at 400 horsepower and 413 pound-feet of torque in its final model years. It was paired with a seven-speed automatic transmission. The engine delivered the smooth, predictable response many buyers associate with a large luxury SUV, and its design had years of real-world service history.
The redesigned QX80 uses a 3.5-liter twin-turbocharged V6 rated at 450 horsepower and 516 pound-feet of torque. A nine-speed automatic transmission replaces the previous seven-speed. The newer powertrain produces substantially more torque, which can make acceleration and passing feel easier despite the vehicle’s size. It also introduces turbochargers, additional heat-management demands and newer control systems that may be less familiar to owners accustomed to the V8.
Towing Capacity Remains a Core Strength
Both generations can be rated to tow up to 8,500 pounds when properly equipped, so the new model does not abandon the capability that made the QX80 useful for boats and trailers. The newer generation adds towing-focused technology such as trailer-related camera views and available trailer blind-spot monitoring, depending on trim and equipment.
Maximum ratings do not replace payload calculations. Passengers, luggage, accessories and trailer tongue weight all count against the vehicle’s available payload. Anyone who tows should verify the certification label, hitch equipment and owner’s manual for the exact vehicle rather than relying only on a promotional maximum.
Ride and Suspension Technology
The previous generation offered a comfortable, truck-based ride but retained noticeable body movement and traditional full-size SUV behavior. Its suspension can be easier for independent shops to understand, although age-related wear and certain hydraulic or load-leveling components can still be expensive.
The redesigned QX80 offers available electronic air suspension and Dynamic Digital Suspension. The air suspension can lower the vehicle for easier entry and raise it for additional ground clearance. These systems can improve comfort, control and convenience, but they also add sensors, actuators, air components and software. Buyers who prioritize long-term simplicity may prefer a less complex configuration, while those who value refinement may see the technology as a major advantage.
Exterior Size and Presence
The new QX80 remains unmistakably a full-size SUV. Its proportions are cleaner and more upright, with flush door handles, a broader visual stance and modern lighting. The redesign does not turn it into a crossover; it remains a substantial vehicle that requires attention in parking structures, narrow garages and older urban spaces.
Shoppers should compare actual garage clearance, mirror width and parking needs rather than assuming that familiar model names mean identical dimensions. The new model’s camera systems can make maneuvering easier, but they do not change the physical footprint.
Interior and Technology Transformation
The previous QX80’s interior is traditional, with physical controls and an infotainment design that evolved over many years. Later versions gained updated displays and smartphone integration, but the cabin architecture still reflects an earlier era. Some buyers appreciate its straightforward controls and familiar layout.
The redesigned QX80 moves to a far more digital environment with large displays, extensive camera views, available head-up information and newer connected services. Depending on trim, buyers can find premium Klipsch audio, biometric cooling technology and advanced seating features. The cabin feels more competitive with newer luxury SUVs, but the quantity of technology means a buyer should test every feature and understand subscription terms before purchase.
Passenger Space and Seating
Both generations provide three rows and configurations for seven or eight occupants. The newer cabin places greater emphasis on third-row comfort, power operation and climate management. It also offers a more modern approach to cargo and passenger technology.
Seat count alone does not show how a family will use the vehicle. Bring child seats, test access to the third row and check cargo space with all seats occupied. A seven-passenger configuration with captain’s chairs may be more comfortable, while an eight-passenger bench provides greater seating flexibility.
Safety and Driver Assistance
Older QX80 models may include adaptive cruise control, lane-related assistance, blind-spot systems and a surround-view camera, but availability varies by year and package. The redesigned model integrates newer versions of these technologies and adds more sophisticated parking and trailer views.
Driver-assistance technology should be treated as support, not autonomous driving. Buyers should read the owner’s manual, keep cameras and sensors clean and understand when a feature may not operate because of weather, road markings or visibility.
Ownership Cost and Long-Term Risk
A previous-generation QX80 usually costs much less to buy, but the savings can be offset by age, mileage, fuel use and deferred maintenance. A new-generation QX80 includes warranty coverage and modern features but carries a higher purchase price, more expensive insurance exposure and less long-term reliability history.
The older V8 is familiar and relatively proven, while the newer twin-turbo V6 is stronger and more efficient in design but mechanically more complex. Neither choice is automatically inexpensive. Tires, brakes, fuel and full-size SUV service remain major expenses across both generations.
Which QX80 Is the Better Choice?
Choose the previous generation when purchase value, traditional V8 response and established repair knowledge matter most. Look for complete records, matching tires, clean electronics and a thorough inspection. Avoid buying solely because the price is low.
Choose the new generation when modern technology, stronger torque, improved cabin presentation and advanced suspension or towing features justify the additional cost. The best decision comes from comparing specific vehicles and trims rather than judging the generations only by horsepower or screen size.
