Both the Suburban and QX60 have child safety locks to prevent children from opening the rear doors. The Suburban 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 QX60’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 Suburban are reminded to check the back seat if they opened the rear door before starting out. The QX60 doesn’t offer a back seat reminder.

The Suburban 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 QX60 doesn’t offer front seat center airbags.

When descending a steep, off-road slope, the Suburban Z71’s standard Hill Descent Control allows you to creep down safely. The QX60 doesn’t offer Hill Descent Control.

Both the Suburban and the QX60 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 Chevrolet Suburban weighs 1034 to 1419 pounds more than the Infiniti QX60. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Chevrolet Suburban is safer than the Infiniti QX60:

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 QX60 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 start during all conditions and help handle large electrical loads, the Suburban has a standard 720-amp battery. The QX60’s 550-amp battery isn’t as powerful.

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.

An engine control system that can shut down half of the engine’s cylinders helps improve the Suburban’s fuel efficiency. The QX60 doesn’t offer a system that can shut down part of the engine.

The Suburban has 11.5 gallons more fuel capacity than the QX60 (31 vs. 19.5 gallons), for longer range between fill-ups.

For better traction, the Suburban has larger standard tires than the QX60 (265/65R18 vs. 235/65R18). The Suburban’s optional tires are larger than the largest tires available on the QX60 (285/45R22 vs. 235/65R18).

The Suburban’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 QX60 Luxe’s optional 55 series tires.

For better ride, handling and brake cooling the Suburban offers optional 22-inch wheels. The QX60’s largest wheels are only 20-inches.

The Chevrolet Suburban’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Infiniti QX60 only has 5 wheel lugs per wheel.

The Suburban 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 QX60 doesn’t offer vehicle monitored tire inflation.

The Suburban has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the QX60, it requires you to depend on a temporary spare, which limits mileage and speed before replacement.

Suspension and Handling

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 QX60’s suspension doesn’t offer adjustable shock absorbers.

The Suburban offers an optional automatic rear load leveling suspension to keep ride height level with a heavy load or when towing. The QX60 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Suburban’s wheelbase is 15.8 inches longer than on the QX60 (130 inches vs. 114.2 inches).

For better handling and stability, the track (width between the wheels) on the Suburban is 3 inches wider in the front and 3 inches wider in the rear than on the QX60.

The Suburban’s front to rear weight distribution is more even (52% to 48%) than the QX60’s (56.3% to 43.7%). This gives the Suburban more stable handling and braking.

The Suburban Premier handles at .77 G’s, while the QX60 AWD pulls only .76 G’s of cornering force in a Motor Trend skidpad test.

The Suburban Premier executes Motor Trend’s “Figure Eight” maneuver 1.5 seconds quicker than the QX60 AWD (27.8 seconds @ .62 average G’s vs. 29.3 seconds @ .56 average G’s).

For greater off-road capability the Suburban has a 1.4 inches greater minimum ground clearance than the QX60 (7.9 vs. 6.5 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 QX60 doesn’t offer active grille shutters.

The Suburban’s minimum standard towing capacity is much higher than the QX60’s (6000 vs. 5000 pounds). Maximum trailer towing in the Infiniti QX60 is only 5000 pounds. The Suburban offers up to a 8300 lbs. towing capacity.

The Suburban 4WD 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 QX60 can’t be towed flat on the ground.

The engine in the Suburban is mounted longitudinally (North-South), instead of sideways, as in the QX60. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

The Suburban’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The QX60 does not have an oil pressure gauge.

The Suburban 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 QX60 doesn’t offer a heads-up display.

The power windows standard on both the Suburban and the QX60 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 QX60 prevents the driver from operating the other windows just as it does the other passengers.

The Suburban’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The QX60’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Chevrolet Suburban Premier has a standard wireless phone charging system (Qi) for the front seat. The QX60 doesn’t offer wireless personal charging.
