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

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 Yukon doesn’t offer a whiplash protection system.

The QX80 offers optional Intelligent Brake Assist, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Yukon doesn't offer collision warning or crash mitigation brakes.

The QX80’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The Yukon doesn’t offer a lane departure warning system.

The QX80 has a standard Around View Monitor to allow the driver to see objects all around the vehicle on a screen. The Yukon only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

Both the QX80 and the Yukon 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 and available all wheel drive.

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 Yukon’s 3 year/36,000 mile basic warranty expires 1 year and 24,000 miles sooner.

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

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

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

To reliably start during all conditions and help handle large electrical loads, the QX80 has a standard 780 amp battery. The Yukon’s 660 amp battery isn’t as powerful.

For better traction, the QX80 has larger tires than the Yukon (275/60R20 vs. 265/70R17).

The QX80’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 Yukon’s standard 70 series tires.

For better ride, handling and brake cooling the QX80 has standard 20-inch wheels. Smaller 17-inch wheels are standard on the Yukon.

For superior ride and handling, the Infiniti QX80 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 GMC Yukon has a solid rear axle, with a non-independent rear suspension.

The QX80 has standard front and rear gas-charged shocks for better control over choppy roads. The Yukon’s suspension doesn’t offer gas-charged shocks.

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

The QX80 offers an available active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. GMC doesn’t offer an active suspension on the Yukon.

The QX80 has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Yukon doesn’t offer variable-assist power steering.

For a smoother ride and more stable handling, the QX80’s wheelbase is 5.1 inches longer than on the Yukon (121.1 inches vs. 116 inches).

The QX80 AWD handles at .74 G’s, while the Yukon SLT 4x4 pulls only .69 G’s of cornering force in a Motor Trend skidpad test.

For greater off-road capability the QX80 has a greater minimum ground clearance than the Yukon (9.2 vs. 9 inches), allowing the QX80 to travel over rougher terrain without being stopped or damaged.

The QX80 has .8 inches more rear headroom, 2 inches more rear legroom and 3.2 inches more third row legroom than the Yukon.

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

The QX80 has a standard third row seat which folds flat into the floor. This completely clears a very large cargo area quickly, without having to lift, carry or store heavy seats, like in the Yukon.

Both the QX80 and the Yukon offer second row automatic folding seats. The QX80’s third row seats also fold up or down at the press of a button. The Yukon doesn’t offer automatic folding third row seats.

The QX80’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the Yukon, and is not available on all models.

The QX80’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 Yukon’s power window switches have to be held the entire time to close them fully. Only its driver’s window opens automatically.

If the windows are left down on the QX80 the driver can raise them all using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the Yukon can only operate the windows from inside the vehicle, with the ignition on.

Infiniti Intelligent Key standard on the QX80 allows you to unlock the doors, cargo door and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The GMC Yukon doesn’t offer an advanced key system.

The QX80 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 Yukon doesn’t offer a locking fuel door.

The QX80’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 Yukon’s manually variable intermittent wipers have to be constantly adjusted.

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 AWD offers available headlight washers to keep headlight output high. The Yukon doesn’t offer headlight washers.

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

A built-in pollen filter removes pollen, exhaust fumes and other pollutants from the QX80’s passenger compartment. This helps prevent lung and/or sinus irritation, which can trigger allergies or asthma. The Yukon doesn’t offer a filtration system.

To keep a safe, consistent following distance, the QX80 offers an optional Intelligent Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Yukon doesn’t offer an adaptive cruise control.

The QX80 offers an optional 115 volt a/c outlet in the center console, allowing you to recharge a laptop or run small household appliances without special adapters which can break or get misplaced. The Yukon doesn’t offer a house-current electrical outlet.

The QX80 will cost the buyer less in the long run because of its superior resale value. Kiplinger’s estimates that the QX80 will retain 40% of its original price after five years, while the Yukon only retains 34% to 37%.

According to The Car Book by Jack Gillis, the QX80 is less expensive to operate than the Yukon because it costs $154 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the QX80 than the Yukon, including $361 less for a water pump, $521 less for an alternator, $101 less for front brake pads and $121 less for a fuel pump.
