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 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.


The Suburban’s standard 5.3 V8 produces 60 more horsepower (355 vs. 295) and 113 lbs.-ft. more torque (383 vs. 270) than the QX60’s 3.5 DOHC V6. The Suburban’s optional 6.2 V8 produces 125 more horsepower (420 vs. 295) and 190 lbs.-ft. more torque (460 vs. 270) than the QX60’s 3.5 DOHC V6.

Fuel Economy and Range

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.

Brakes and Stopping

For better stopping power the Suburban’s brake rotors are larger than those on the QX60:



Front Rotors

13 inches

12.6 inches

Rear Rotors

13.6 inches

12.13 inches

Tires and Wheels

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 (56.4% to 43.6%). 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.

Passenger Space

The Suburban offers optional seating for 9 passengers; the QX60 can only carry 7.

The Suburban has 2.1 inches more front headroom, 3.1 inches more front legroom, 4 inches more front hip room, 4.5 inches more front shoulder room, .9 inches more rear headroom, 4.5 inches more rear hip room, 4.7 inches more rear shoulder room, 2 inches more third row headroom, 3.7 inches more third row legroom, 7.3 inches more third row hip room and 5.5 inches more third row shoulder room than the QX60.

Cargo Capacity

The Suburban’s cargo area provides more volume than the QX60.



Behind Third Seat

39.3 cubic feet

16 cubic feet

Third Seat Folded

76.7 cubic feet

40.5 cubic feet

Second Seat Folded

121.1 cubic feet

76.2 cubic feet

The Suburban’s cargo area is larger than the QX60’s in every dimension:



Length to seat (3rd/2nd/1st)



Min Width






Pressing a switch automatically lowers the Suburban’s (except LS) optional second and third row seats, to make changing between passengers and cargo easier. The QX60 doesn’t offer automatic folding second row seats.

The Suburban’s rear cargo window opens separately from the rest of the liftgate door to allow quicker loading of small packages. The QX60’s rear cargo window doesn’t open.


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 an 8300 lbs. towing capacity.

Servicing Ease

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.

Economic Advantages

Insurance will cost less for the Suburban owner. The Complete Car Cost Guide estimates that insurance for the Suburban will cost $930 to $1360 less than the QX60 over a five-year period.

According to The Car Book by Jack Gillis, the Suburban is less expensive to operate than the QX60 because typical repairs cost much less on the Suburban than the QX60, including $3 less for a muffler, $167 less for a starter, $41 less for fuel injection, $139 less for front struts and $862 less for a power steering pump.
