Safety

The QX60 Luxe’s optional 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.

Over 200 people are killed each year when backed over by motor vehicles. The QX60 Luxe offers an optional Backup Collision Intervention that use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Suburban doesn’t offer backup collision prevention brakes.

The QX60 Luxe offers an optional Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The Suburban only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

For better protection of the passenger compartment, the QX60 uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The Suburban uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the QX60 and the Suburban 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 and lane departure warning systems.

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

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the QX60 the rating of “Top Pick” for 2017, a rating granted to only 157 vehicles tested by the IIHS. The Suburban has not been tested, yet.

Warranty

The QX60 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 and 24,000 miles sooner.

Infiniti’s powertrain warranty covers the QX60 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 QX60’s corrosion warranty is 1 year and unlimited miles longer than the Suburban’s (7/unlimited vs. 6/100,000).

Reliability

For smoother operation, better efficiency and fewer moving parts, the QX60 has an overhead cam design, rather than the old pushrod design of the engines in the Suburban.

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 QX60’s reliability 11 points higher than the Suburban.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Infiniti vehicles are more reliable than Chevrolet vehicles. Consumer Reports ranks Infiniti 17 places higher in reliability than Chevrolet.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Infiniti QX60 higher (5 out of 10) than the Chevrolet Suburban (3). This means the QX60 produces up to 16.5 pounds less smog-producing pollutants than the Suburban every 15,000 miles.

The QX60 has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The Suburban doesn’t offer a CVT.

Brakes and Stopping

The QX60 stops much shorter than the Suburban:

Consumer Reports

Suspension and Handling

For superior ride and handling, the Infiniti QX60 has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Chevrolet Suburban has a solid rear axle, with a non-independent rear suspension.

The QX60 has standard front and rear stabilizer bars, which help keep the QX60 flat and controlled during cornering. The Suburban’s suspension doesn’t offer a rear stabilizer bar.

The QX60 AWD handles at .76 G’s, while the Suburban Premier 4WD pulls only .75 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the QX60’s turning circle is 4.3 feet tighter than the Suburban’s (38.7 feet vs. 43 feet).

Chassis

The Infiniti QX60 may be more efficient, handle and accelerate better because it weighs about 1200 to 1250 pounds less than the Chevrolet Suburban.

The QX60 is 1 foot, 11.8 inches shorter than the Suburban, making the QX60 easier to handle, maneuver and park in tight spaces.

Unibody construction lowers the QX60’s center of gravity significantly without reducing ground clearance. This contributes to better on the road handling and better off-road performance and stability. In addition, unibody construction makes the chassis stiffer, improving handling and reducing squeaks and rattles. The Suburban uses body-on-frame design instead.

Passenger Space

For enhanced passenger comfort on long trips the QX60’s middle and third row seats recline. The Suburban’s third row seats don’t recline.

The front step up height for the QX60 is 3.8 inches lower than the Suburban (18.2” vs. 22”).

Cargo Capacity

A low lift-over cargo hatch design makes loading and unloading the QX60 easier. The QX60’s cargo hatch lift-over height is 30.6 inches, while the Suburban’s liftover is 34.1 inches.

The QX60 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.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than Chevrolet. J.D. Power ranks Infiniti fourth in service department satisfaction. With a 33% lower rating, Chevrolet is ranked 13th.

Ergonomics

The QX60’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Suburban’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the QX60 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 operate the windows from inside the vehicle, with the ignition on.

The QX60 has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent vandalism, such as sugar in the tank and fuel theft. The Suburban doesn’t offer a locking fuel door.

Consumer Reports rated the QX60’s headlight performance “Very Good,” a higher rating than the Suburban’s headlights, which were rated “Good.”

Economic Advantages

Insurance will cost less for the QX60 owner. The Car Book by Jack Gillis rates the QX60 with a number “8” insurance rate while the Suburban is rated higher at a number “10” rate.

The QX60 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the QX60 will retain 54.7% to 54.76% of its original price after five years, while the Suburban only retains 52.55% to 53.03%.

According to The Car Book by Jack Gillis, the QX60 is less expensive to operate than the Suburban because it costs $191 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost less on the QX60 than the Suburban, including $121 less for a water pump, $47 less for front brake pads, $147 less for a fuel pump and $164 less for a timing belt/chain.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Infiniti QX60 will be $4305 to $14129 less than for the Chevrolet Suburban.
