Safety

Both the Tahoe and QX80 have child safety locks to prevent children from opening the rear doors. The Tahoe 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.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Tahoe are reminded to check the back seat if they opened the rear door before starting out. The QX80 doesn’t offer a back seat reminder.

The Tahoe 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.

When descending a steep, off-road slope, the Tahoe Z71’s standard Hill Descent Control allows you to creep down safely. The QX80 doesn’t offer Hill Descent Control.

Both the Tahoe and the QX80 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems, front parking sensors and rear cross-path warning.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Chevrolet Tahoe is safer than the Infiniti QX80:

Warranty

There are over 14 times as many Chevrolet dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the Tahoe’s warranty.

Reliability

The Tahoe 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.

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 Tahoe’s reliability 12 points higher than the QX80.

J.D. Power and Associates rated the Tahoe first among large SUVs in their 2019 Initial Quality Study. The QX80 isn’t in the top three in its category.

J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Chevrolet vehicles are better in initial quality than Infiniti vehicles. J.D. Power ranks Chevrolet 6th in initial quality, above the industry average. With 16 more problems per 100 vehicles, Infiniti is ranked 19th, below the industry average.

J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Chevrolet vehicles are more reliable than Infiniti vehicles. J.D. Power ranks Chevrolet fourth in reliability, above the industry average. With 13 more problems per 100 vehicles, Infiniti is ranked 11th.

Engine

The Tahoe’s optional 6.2 V8 produces 20 more horsepower (420 vs. 400) and 47 lbs.-ft. more torque (460 vs. 413) than the QX80’s 5.6 DOHC V8.

Consumer Reports

Tires and Wheels

For better traction, the Tahoe’s optional tires are larger than the largest tires available on the QX80 (285/45R22 vs. 275/60R20).

The Tahoe’s optional tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the QX80’s optional 50 series tires.

The Tahoe has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The QX80 doesn’t offer vehicle monitored tire inflation.

Suspension and Handling

The Tahoe 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 handling and stability, the track (width between the wheels) on the Tahoe is 1.2 inches wider in the front and .8 inches wider in the rear than on the QX80.

The Tahoe Premier 4x4 handles at .79 G’s, while the QX80 AWD pulls only .72 G’s of cornering force in a Car and Driver skidpad test.

The Tahoe LT executes Motor Trend’s “Figure Eight” maneuver quicker than the QX80 AWD (27.9 seconds @ .72 average G’s vs. 28.6 seconds @ .57 average G’s).

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

Chassis

The Chevrolet Tahoe may be more efficient, handle and accelerate better because it weighs about 300 pounds less than the Infiniti QX80.

The Tahoe is 6.2 inches shorter than the QX80, making the Tahoe easier to handle, maneuver and park in tight spaces.

The front grille of the Tahoe 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.

Passenger Space

The Tahoe offers optional seating for 9 passengers; the QX80 can only carry up to 8.

The Tahoe has 2.9 inches more front headroom, 5.7 inches more front legroom, 1.6 inches more front hip room, 1 inch more front shoulder room, 1.9 inches more rear hip room, 1.6 inches more rear shoulder room, 1.3 inches more third row headroom, .5 inches more third row hip room and 2.1 inches more third row shoulder room than the QX80.

Cargo Capacity

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

The Tahoe’s rear cargo window opens separately from the rest of the liftgate door to allow quicker loading of small packages. The QX80’s rear cargo window doesn’t open.

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

Towing

Maximum trailer towing in the Infiniti QX80 is limited to 8500 pounds. The Tahoe offers up to a 8600 lbs. towing capacity.

Servicing Ease

The Tahoe 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.

Ergonomics

The Tahoe Premier offers an optional 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 power windows standard on both the Tahoe and the QX80 have locks to prevent small children from operating them. When the lock on the Tahoe 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.

Economic Advantages

Insurance will cost less for the Tahoe owner. The Complete Car Cost Guide estimates that insurance for the Tahoe will cost $3520 to $5520 less than the QX80 over a five-year period.

The Tahoe will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Tahoe will retain 50.08% to 50.55% of its original price after five years, while the QX80 only retains 43.69% to 48.1%.

According to The Car Book by Jack Gillis, the Tahoe is less expensive to operate than the QX80 because typical repairs cost much less on the Tahoe than the QX80, including $158 less for a starter, $17 less for front struts, $50 less for a timing belt/chain and $747 less for a power steering pump.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Chevrolet Tahoe will be $19590 to $30947 less than for the Infiniti QX80.

Recommendations

The Chevrolet Tahoe outsold the Infiniti QX80 by over five to one during 2018.
