The Acadia Denali’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The QX50 doesn’t offer pre-crash pretensioners.

For enhanced safety, the GMC Acadia’s middle seat shoulder belts have child comfort guides to move the belt to properly fit children. A better fit can prevent injuries and the increased comfort also encourages children to buckle up. The Infiniti QX50 doesn’t offer comfort guides on its middle seat belts.

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 Acadia are reminded to check the back seat if they opened the rear door before starting out. The QX50 doesn’t offer a back seat reminder.

The Acadia 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 QX50 doesn’t offer front seat center airbags.

Both the Acadia and the QX50 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front-wheel drive, 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, around view monitors and rear cross-path warning.

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 Acadia the rating of “Top Pick” for 2017, a rating granted to only 154 vehicles tested by the IIHS. The QX50 has not been tested, yet.

GMC pays for the first scheduled maintenance on the Acadia. GMC will pay for the first oil change, lubrication and any other required maintenance in the first year. Infiniti doesn’t pay scheduled maintenance for the QX50.

There are over 8 times as many GMC dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the Acadia’s warranty.

To reliably power the ignition and other systems and to recharge the battery, the Acadia has a standard 150-amp alternator (155-amp - Acadia V6 and 170 V6). The QX50’s 130-amp alternator isn’t as powerful.

The Acadia’s optional 3.6 DOHC V6 produces 42 more horsepower (310 vs. 268) than the QX50’s 2.0 turbo 4 cyl.

In heavy traffic or at stoplights the Acadia 4 cyl.’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The QX50 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the GMC Acadia uses regular unleaded gasoline. The QX50 requires premium, which can cost 20 to 55 cents more per gallon.

The Acadia FWD’s standard fuel tank has 3.4 gallons more fuel capacity than the QX50 (19.4 vs. 16 gallons), for longer range between fill-ups. The Acadia AWD’s standard fuel tank has 5.7 gallons more fuel capacity than the QX50 (21.7 vs. 16 gallons).

The Acadia has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The QX50 doesn’t offer a cap-less fueling system.

The GMC Acadia’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Infiniti QX50 only has 5 wheel lugs per wheel.

The Acadia SLE/SLT/Denali has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the QX50; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

Suspension and Handling

The Acadia 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 QX50’s suspension doesn’t offer adjustable shock absorbers.

For a smoother ride and more stable handling, the Acadia’s wheelbase is 2.3 inches longer than on the QX50 (112.5 inches vs. 110.2 inches).

The Acadia’s front to rear weight distribution is more even (56.5% to 43.5%) than the QX50’s (58.8% to 41.2%). This gives the Acadia more stable handling and braking.

The front grille of the Acadia FWD 4 cyl. uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The QX50 doesn’t offer active grille shutters.

The power windows standard on both the Acadia and the QX50 have locks to prevent small children from operating them. When the lock on the Acadia is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The QX50 prevents the driver from operating the other windows just as it does the other passengers.

The Acadia’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Infiniti only offers heated mirrors on the QX50 Essential.

The Acadia SLT/Denali has standard automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The QX50 offers an automatic rear view mirror, but its side mirrors don’t dim.

Both the Acadia and the QX50 offer available heated front seats. The Acadia also offers optional heated second row seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the QX50.

Standard smartphone integration for the Acadia allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations and other connected activities without taking their eyes off the road or their hands from the wheel. The QX50 doesn’t offer factory integrated smartphone program access.

The Acadia SLT/Denali has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The QX50 doesn’t offer a house-current electrical outlet.
