Compare the2025 Chevrolet SuburbanVS 2024 Infiniti QX80

The Suburban (except LS with front bench seat) 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 Suburban 4WD’s optional Hill Descent Control allows you to creep down safely. The QX80 doesn’t offer Hill Descent Control.

Both the Suburban 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, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and available all wheel drive.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

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 Suburban’s warranty.

The Suburban 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 Suburban has a standard 220-amp alternator (250-amp - Suburban Diesel). The QX80’s 150-amp alternator isn’t as powerful.

J.D. Power and Associates’ 2024 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 second in initial quality, above the industry average. With 27 more problems per 100 vehicles, Infiniti is ranked 14th.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the 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 45 more problems per 100 vehicles, Infiniti is ranked 22nd.

The Suburban’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.

The Suburban’s 3.0 turbo diesel produces 82 lbs.-ft. more torque (495 vs. 413) than the QX80’s 5.6 DOHC V8.

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

An engine control system that can shut down some of the engine’s cylinders helps improve the Suburban V8’s fuel efficiency. The QX80 doesn’t offer a system that can shut down part of the engine.

In heavy traffic or at stoplights the Suburban’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.

The Suburban has 2.3 gallons more fuel capacity than the QX80 (28.3 vs. 26 gallons), for longer range between fill-ups.

The Suburban 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.

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

For better stopping power the Suburban’s front brake rotors are larger than those on the QX80:

The Suburban stops shorter than the QX80:

For better traction, the Suburban RST’s optional tires are larger than the largest tires available on the QX80 (285/40R24 vs. 275/60R20).

The Suburban RST’s optional tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the QX80 Premium Select/Sensory’s 50 series tires.

For better ride, handling and brake cooling the Suburban RST offers optional 24-inch wheels. The QX80’s largest wheels are only 22-inches.

The Suburban 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 a smoother ride and more stable handling, the Suburban’s wheelbase is 13 inches longer than on the QX80 (134.1 inches vs. 121.1 inches).

For greater off-road capability the Suburban Z71 Air Ride has a greater minimum ground clearance than the QX80 (10 vs. 9.2 inches), allowing the Suburban to travel over rougher terrain without being stopped or damaged.

The front grille of the Suburban 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 Suburban offers optional seating for 9 passengers; the QX80 can only carry up to 8.

The Suburban has 18.3 cubic feet more passenger volume than the QX80 (170.8 vs. 152.5).

The Suburban has 2.4 inches more front headroom, 4.9 inches more front legroom, 2.3 inches more front hip room, 1.7 inches more front shoulder room, 1 inch more rear legroom, 2.9 inches more rear hip room, 1.1 inches more rear shoulder room, 1.4 inches more third row headroom, 7.9 inches more third row legroom, .6 inches more third row hip room and 2.3 inches more third row shoulder room than the QX80.

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

To make loading groceries and cargo easier when your hands are full, the Suburban Premier/High Country’s available liftgate can be opened just by waiting momentarily behind 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.

The Suburban 4WD with optional equipment can be flat towed on all four wheels (dinghy towed), allowing recreational vehicle owners to bring it with them on the road. When they reach their destination, the Suburban can be unhitched and driven around locally. The QX80 can’t be towed flat on the ground.

The Suburban (except LS) offers an available heads-up display that projects speed, warning and navigation instruction 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 Suburban’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 Suburban and the QX80 have locks to prevent small children from operating them. When the lock on the Suburban 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 Suburban’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 Suburban’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 Suburban’s Enhanced Automatic Parking Assist 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.

Insurance will cost less for the Suburban owner. The Complete Car Cost Guide estimates that insurance for the Suburban will cost $3250 to $5580 less than the QX80 over a five-year period.

The Suburban will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Suburban will retain 54.17% to 56.59% of its original price after five years, while the QX80 only retains 51% to 51.42%.

According to The Car Book by Jack Gillis, the Suburban is less expensive to operate than the QX80 because typical repairs cost much less on the Suburban than the QX80, including $159 less for a starter, $11 less for front struts, $50 less for a timing belt/chain and $746 less for a power steering pump.

The Chevrolet Suburban outsold the Infiniti QX80 by over four to one during 2023.
