The Enclave has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The QX80 doesn’t offer front seat center airbags.

For better protection of the passenger compartment, the Enclave 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 Enclave and the QX80 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and around view monitors.

Warranty

There are over 5 times as many Buick dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the Enclave’s warranty.

Reliability

To reliably power the ignition and other systems and to recharge the battery, the Enclave has a standard 170-amp alternator. The QX80’s 150-amp alternator isn’t as powerful.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Enclave’s reliability 25 points higher than the QX80.

J.D. Power and Associates rated the Enclave second among midsize suvs in their 2023 Initial Quality Study. The QX80 isn’t in the top three in its category.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Buick vehicles are better in initial quality than Infiniti vehicles. J.D. Power ranks Buick fourth in initial quality, above the industry average. With 50 more problems per 100 vehicles, Infiniti is ranked 29th, below the industry average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the statistics that show that Buick vehicles are more reliable than Infiniti vehicles. J.D. Power ranks Buick second in reliability, above the industry average. With 81 more problems per 100 vehicles, Infiniti is ranked 23rd.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Buick vehicles are more reliable than Infiniti vehicles. Consumer Reports ranks Buick 1 place higher in reliability than Infiniti.

Fuel Economy and Range

On the EPA test cycle the Enclave gets better mileage than the QX80:

			MPG
Enclave
	FWD	3.6 DOHC V6	18 city/26 hwy
	AWD	3.6 DOHC V6	17 city/25 hwy
QX80
	RWD	5.6 DOHC V8	14 city/20 hwy
	AWD	5.6 DOHC V8	13 city/19 hwy

In heavy traffic or at stoplights the Enclave’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. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The QX80 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Buick Enclave uses regular unleaded gasoline. The QX80 requires premium for maximum efficiency, which can cost on average about 82.8 cents more per gallon.

The Enclave 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.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Buick Enclave higher (6 out of 10) than the Infiniti QX80 (5). This means the Enclave produces up to 6.9 pounds less smog-producing pollutants than the QX80 every 15,000 miles.

Transmission

A nine-speed automatic is standard on the Buick Enclave, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the QX80.

Brakes and Stopping

The Enclave stops shorter than the QX80:

	Enclave	QX80
70 to 0 MPH	176 feet	185 feet	Car and Driver
60 to 0 MPH	130 feet	139 feet	Consumer Reports
60 to 0 MPH (Wet)	141 feet	155 feet	Consumer Reports

Suspension and Handling

The Enclave 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.

The Enclave Avenir AWD handles at .83 G’s, while the QX80 AWD pulls only .72 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the Enclave’s turning circle is 2.3 feet tighter than the QX80’s (39 feet vs. 41.3 feet).

Chassis

The Buick Enclave may be more efficient, handle and accelerate better because it weighs about 1350 to 1400 pounds less than the Infiniti QX80.

The Enclave is 5.4 inches shorter than the QX80, making the Enclave easier to handle, maneuver and park in tight spaces.

Unibody construction lowers the Enclave’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 doesn’t use unibody construction, but a body-on-frame design.

The front grille of the Enclave 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 Enclave 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 Enclave has 4.8 cubic feet more passenger volume than the QX80 (157.3 vs. 152.5).

The Enclave has 2.7 inches more front headroom, 1.6 inches more front legroom, .8 inches more third row headroom and 4.7 inches more third row legroom than the QX80.

The front step up height for the Enclave is 4.4 inches lower than the QX80 (18” vs. 22.4”). The Enclave’s rear step up height is 4.1 inches lower than the QX80’s (18.7” vs. 22.8”).

Cargo Capacity

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

	Enclave	QX80
Behind Third Seat	23.6 cubic feet	16.6 cubic feet
Third Seat Folded	57.7 cubic feet	49.6 cubic feet
Second Seat Folded	97.4 cubic feet	95.1 cubic feet

A low lift-over cargo hatch design makes loading and unloading the Enclave easier. The Enclave’s cargo hatch lift-over height is 30.5 inches, while the QX80’s liftover is 35.8 inches.

The Enclave’s cargo area is larger than the QX80’s in almost every dimension:

	Enclave	QX80
Length to seat (3rd/2nd/1st)	26.2”/54”/90”	18.4”/48”/81”
Max Width	52.7”	50”
Min Width	48.5”	49.8”
Height	30.8”	36”

To make loading groceries and cargo easier when your hands are full, the Enclave’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.

Servicing Ease

The Enclave has a maintenance free battery for long life without checking the battery’s water level. The QX80 doesn’t have a maintenance free battery, so the water level in the battery’s cells must be checked often to prevent damage.

J.D. Power and Associates surveys of service recipients show that Buick service is better than Infiniti. J.D. Power ranks Buick fifth in service department satisfaction. With a 10% lower rating, Infiniti is ranked 9th.

Ergonomics

The Enclave Premium/Avenir has a standard heads-up display that projects speed and tachometer 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 Enclave’s power parking brake sets with one touch and releases with one touch or automatically. The QX80’s parking brake has to be released manually.

The power windows standard on both the Enclave and the QX80 have locks to prevent small children from operating them. When the lock on the Enclave 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 Enclave’s available exterior PIN entry system. The QX80 doesn’t offer an exterior PIN entry system, and its Emergency Call with Automatic Collision Notification can’t unlock the doors if the vehicle doesn’t have cell phone reception or the driver can’t contact the service.

The Enclave’s standard Keyless Access allow you to unlock the doors from any outside door handle, open the cargo door, and start the engine, all without removing the key from the pocket or purse. Infiniti Intelligent Key standard on the QX80 doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door.

The Enclave Premium/Avenir has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the QX80.

Economic Advantages

Insurance will cost less for the Enclave owner. The Complete Car Cost Guide estimates that insurance for the Enclave will cost $3110 to $5840 less than the QX80 over a five-year period.

According to The Car Book by Jack Gillis, the Enclave is less expensive to operate than the QX80 because typical repairs cost much less on the Enclave than the QX80, including $74 less for a starter, $66 less for front struts and $500 less for a timing belt/chain.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Buick Enclave will be $28879 to $31715 less than for the Infiniti QX80.
