For enhanced safety, the front and second-row seat shoulder belts of the Infiniti QX80 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Chevrolet Suburban doesn’t offer pretensioners for its second-row seat belts.

The QX80 Sensory’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Suburban doesn’t offer pre-crash pretensioners.

The Infiniti QX80 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Suburban doesn’t offer knee airbags.

The QX80 has standard Active Head Restraints (AHR), which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the AHR system moves the headrests forward to prevent neck and spine injuries. The Suburban doesn’t offer a whiplash protection system.

The QX80 has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the Suburban’s blind spot costs extra.

To help make backing out of a parking space safer, the QX80 has standard Rear Cross Traffic Alert and Back-up Collision Intervention automatically engages the brakes to help avoid a collision. Chevrolet charges extra for Rear Cross Traffic Alert on the Suburban and the Suburban’s Rear Cross Traffic Alert does not include automatic braking.

Both the QX80 and the Suburban have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, 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, rearview cameras and available all wheel drive.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Infiniti QX80 is safer than the Chevrolet Suburban:

	QX80	Suburban
	Front Seat
STARS	5 Stars	5 Stars
Abdominal Force	81 lbs.	111 lbs.
	Rear Seat
STARS	5 Stars	5 Stars
HIC	31	88
Spine Acceleration	21 G’s	24 G’s
Hip Force	151 lbs.	248 lbs.
	Into Pole
STARS	5 Stars	5 Stars
Hip Force	684 lbs.	764 lbs.

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

Warranty

The QX80 comes with a full 4-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Suburban’s 3-year/36,000-mile basic warranty expires 1 year or 24,000 miles sooner.

Infiniti’s powertrain warranty covers the QX80 1 year and 10,000 miles longer than Chevrolet covers the Suburban. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Suburban ends after only 5 years or 60,000 miles.

The QX80’s corrosion warranty is 1 year and unlimited miles longer than the Suburban’s (7/unlimited vs. 6/100,000).

Infiniti pays for scheduled maintenance on the QX80 for 3 years and 45000 miles. Infiniti will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Chevrolet only pays for the first scheduled maintenance visit on the Suburban.

Reliability

For smoother operation, better efficiency and fewer moving parts, the QX80 has an overhead cam design, rather than the old pushrod design of some of the engines in the Suburban.

To reliably start during all conditions and help handle large electrical loads, the QX80 has a 780-amp battery. The Suburban only offers a standard 730-amp battery.

Engine

The QX80’s 5.6 DOHC V8 produces 45 more horsepower (400 vs. 355) and 30 lbs.-ft. more torque (413 vs. 383) than the Suburban’s standard 5.3 V8.

As tested in Motor Trend the Infiniti QX80 is faster than the Chevrolet Suburban 5.3 V8:

	QX80	Suburban
Zero to 60 MPH	6.1 sec	7.6 sec
Quarter Mile	14.8 sec	15.7 sec
Speed in 1/4 Mile	93.9 MPH	89.6 MPH

Fuel Economy and Range

The QX80 has a standard locking fuel door which locks and unlocks with the power locks. The fuel filler door is not lockable on the Suburban. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

Brakes and Stopping

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

	QX80	Suburban
Front Rotors	13.8 inches	13.5 inches
Rear Rotors	13.8 inches	13.6 inches

The QX80 stops shorter than the Suburban:

	QX80	Suburban
60 to 0 MPH	139 feet	145 feet	Consumer Reports

Tires and Wheels

For better traction, the QX80 has larger tires than the Suburban (275/60R20 vs. 265/65R18).

The QX80 Luxe’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the Suburban’s standard 65 series tires.

For better ride, handling and brake cooling the QX80 Luxe has standard 20-inch wheels. Smaller 18-inch wheels are standard on the Suburban.

Suspension and Handling

The rear suspension of the QX80 uses air springs for a smoother, controlled ride than the Suburban, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The QX80 AWD handles at .72 G’s, while the Suburban High Country 4WD pulls only .53 G’s of cornering force in a Car and Driver skidpad test.

The QX80 AWD executes Motor Trend’s “Figure Eight” maneuver 2.6 seconds quicker than the Suburban Z71 4WD (28.3 seconds @ .64 average G’s vs. 30.9 seconds @ .5 average G’s).

For better maneuverability, the QX80’s turning circle is 1 foot tighter than the Suburban’s (41.3 feet vs. 42.3 feet). The QX80’s turning circle is 2 feet tighter than the Suburban w/20-22 inch wheels’ (41.3 feet vs. 43.3 feet).

For greater off-road capability the QX80 has a 1.2 inches greater minimum ground clearance than the Suburban (9.2 vs. 8 inches), allowing the QX80 to travel over rougher terrain without being stopped or damaged.

Chassis

The QX80 is 1 foot, 3.5 inches shorter than the Suburban, making the QX80 easier to handle, maneuver and park in tight spaces.

Passenger Space

For enhanced passenger comfort on long trips the QX80’s middle and third row seats recline. The Suburban’s third row seats don’t recline.

Cargo Capacity

A low lift-over cargo hatch design makes loading and unloading the QX80 easier. The QX80’s cargo hatch lift-over height is 35.8 inches, while the Suburban’s liftover is 37 inches.

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

	QX80	Suburban
Length to seat (3rd/2nd/1st)	18.4”/48”/81”	n.a./n/a
Max Width	50”	49.5”
Min Width	49.8”	49.4”
Height	36”	36.5”

The QX80 has a standard third row seat which folds flat into the floor. This completely clears a very large cargo area quickly. The Suburban doesn’t offer seats that fold into the floor.

Towing

The QX80’s standard towing capacity is much higher than the Suburban’s (8500 vs. 7600 pounds).

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than Chevrolet. J.D. Power ranks Infiniti 9th in service department satisfaction (above the industry average). With a 10% lower rating, Chevrolet is ranked 16th.

Ergonomics

The QX80’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Suburban’s rear power window switches have to be held the entire time to close them fully.

If the windows are left open on the QX80 the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the Suburban can only close the windows from inside the vehicle, with the ignition on.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The QX80 Sensory has standard headlight washers to keep headlight output high. The Suburban doesn’t offer headlight washers.

To help drivers see further while navigating curves, the QX80 Sensory has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Suburban doesn’t offer cornering lights.

The QX80 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the Suburban.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Infiniti QX80 has a standard wireless phone charging system (Qi) in the center console. Only the Suburban LT/RST/Z71/Premier/High Country offers wireless charging.

Economic Advantages

Insurance will cost less for the QX80 owner. The Car Book by Jack Gillis rates the QX80 with a number “5” insurance rate while the Suburban is rated higher at a number “10” rate.

According to The Car Book by Jack Gillis, the QX80 is less expensive to operate than the Suburban because it costs $200 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the QX80 than the Suburban, including $70 less for a water pump, $201 less for a muffler, $28 less for front brake pads, $44 less for fuel injection and $171 less for a fuel pump.
