Safety

For enhanced safety, the front and middle seat shoulder belts of the Lincoln Aviator have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Infiniti QX80 doesn’t offer pretensioners for the middle seat belts.

Both the Aviator and QX80 have child safety locks to prevent children from opening the rear doors. The Aviator has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The QX80’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The Aviator has standard Post Collision Braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The QX80 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

When descending a steep, off-road slope, the Aviator’s optional Hill Descent Control allows you to creep down safely. The QX80 doesn’t offer Hill Descent Control.

The Aviator’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The QX80 doesn’t offer a driver alert monitor.

For better protection of the passenger compartment, the Aviator uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The QX80 uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the Aviator and the QX80 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available all wheel drive and around view monitors.

Warranty

There are over 4 times as many Lincoln dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the Aviator’s warranty.

Reliability

The Lincoln Aviator’s engines use a cast iron block for durability, while the QX80’s engine uses an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

The Aviator has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The QX80 doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the truck’s engine.

To reliably power the ignition and other systems and to recharge the battery, the Aviator has a standard -amp alternator (250-amp - Aviator optional). The QX80’s 150-amp alternator isn’t as powerful.

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Lincoln vehicles are better in initial quality than Infiniti vehicles. J.D. Power ranks Lincoln fifth in initial quality, above the industry average. With 17 more problems per 100 vehicles, Infiniti is ranked 19th, below the industry average.

Engine

The Aviator’s optional 3.0 turbo V6 hybrid produces 94 more horsepower (494 vs. 400) and 217 lbs.-ft. more torque (630 vs. 413) than the QX80’s 5.6 DOHC V8.

Fuel Economy and Range

On the EPA test cycle the Aviator gets better fuel mileage than the QX80:

Regenerative brakes improve the Aviator Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The QX80 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the Aviator’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The QX80 doesn’t offer an automatic engine start/stop system.

The Aviator has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The QX80 doesn’t offer a cap-less fueling system.

Transmission

A 10-speed automatic is standard on the Lincoln Aviator, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the QX80.

Tires and Wheels

The Aviator’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the QX80’s standard 60 series tires.

Suspension and Handling

The Aviator offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The QX80’s suspension doesn’t offer adjustable shock absorbers.

For better maneuverability, the Aviator’s turning circle is 2.1 feet tighter than the QX80’s (39.2 feet vs. 41.3 feet).

Chassis

The Lincoln Aviator may be more efficient, handle and accelerate better because it weighs about 250 to 900 pounds less than the Infiniti QX80.

The Aviator is 10.9 inches shorter than the QX80, making the Aviator easier to handle, maneuver and park in tight spaces.

Unibody construction lowers the Aviator’s center of gravity significantly without reducing ground clearance. This contributes to better on the road handling and better off-road performance and stability. In addition, unibody construction makes the chassis stiffer, improving handling and reducing squeaks and rattles. The QX80 uses body-on-frame design instead.

The front grille of the Aviator uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The QX80 doesn’t offer active grille shutters.

The Aviator Grand Touring/Black Label uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The QX80 doesn’t offer active noise cancellation.

Passenger Space

The Aviator has 1.6 inches more front headroom, 3.4 inches more front legroom, .1 inches more third row headroom and .4 inches more third row legroom than the QX80.

Cargo Capacity

The Aviator’s cargo area provides more volume than the QX80.

To make loading groceries and cargo easier when your hands are full, the Aviator’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The QX80 doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Ergonomics

The Aviator (except Base) offers an available heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The QX80 doesn’t offer a heads-up display.

The Aviator’s power parking brake sets with one touch and releases with one touch or automatically. The QX80’s parking brake has to released manually.

The power windows standard on both the Aviator and the QX80 have locks to prevent small children from operating them. When the lock on the Aviator is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The QX80 prevents the driver from operating the other windows just as it does the other passengers.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Aviator’s exterior PIN entry system. The QX80 doesn’t offer an exterior PIN entry system, and its Infiniti Connection can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.

Optional air conditioned the front and second row seats keep the Aviator’s passengers comfortable and take the sting out of hot leather in summer. The QX80 doesn’t offer air-conditioned seats for the second row.

The Aviator (except Base)’s optional Active Park Assist Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The QX80 doesn’t offer an automated parking system.
