Compare the2023 Infiniti QX55VS 2023 GMC Acadia

For enhanced safety, the front and rear seat shoulder belts of the Infiniti QX55 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 GMC Acadia doesn’t offer pretensioners for its second-row seat belts.

The Infiniti QX55 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 Acadia doesn’t offer a front passenger side knee airbag.

Over 200 people are killed each year when backed over by motor vehicles. The QX55 has standard Rear Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Acadia doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the QX55. But it costs extra on the Acadia.

Both the QX55 and the Acadia have standard driver and passenger frontal airbags, front side-impact airbags, driver knee 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, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Infiniti QX55 is safer than the GMC Acadia:

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

The QX55 comes with a full 4-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Acadia’s 3-year/36,000-mile basic warranty expires 1 year or 24,000 miles sooner.

Infiniti’s powertrain warranty covers the QX55 1 year and 10,000 miles longer than GMC covers the Acadia. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Acadia ends after only 5 years or 60,000 miles.

The QX55’s corrosion warranty is 1 year and unlimited miles longer than the Acadia’s (7/unlimited vs. 6/100,000).

Infiniti pays for scheduled maintenance on the QX55 for 3 years and 36,000 miles. Infiniti will pay for oil changes, lubrication and any other required maintenance. GMC only pays for the first scheduled maintenance visit on the Acadia.

To reliably start during all conditions and help handle large electrical loads, the QX55 has a standard 720-amp battery. The Acadia’s 660-amp battery isn’t as powerful.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that Infiniti vehicles are more reliable than GMC vehicles. Consumer Reports ranks Infiniti 5 places higher in reliability than GMC.

The QX55’s 2.0 turbo 4-cylinder produces 40 more horsepower (268 vs. 228) and 22 lbs.-ft. more torque (280 vs. 258) than the Acadia’s standard 2.0 turbo 4-cylinder. The QX55’s 2.0 turbo 4-cylinder produces 9 lbs.-ft. more torque (280 vs. 271) than the Acadia’s optional 3.6 DOHC V6.

On the EPA test cycle the QX55 gets better mileage than the Acadia:

The QX55 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 Acadia doesn’t offer a CVT.

For better stopping power the QX55’s front brake rotors are larger than those on the Acadia:

For better traction, the QX55 has larger tires than the Acadia (255/45R20 vs. 235/65R18).

The QX55’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Acadia SLE/SLT’s standard 65 series tires. The QX55’s tires are lower profile than the Acadia’s optional 55 series tires.

For better ride, handling and brake cooling the QX55 has standard 20-inch wheels. Smaller 17-inch wheels are standard on the Acadia AT4.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the QX55 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Acadia doesn’t offer run-flat tires.

For better maneuverability, the QX55’s turning circle is 2.3 feet tighter than the Acadia’s (36.4 feet vs. 38.7 feet).

For greater off-road capability the QX55 has a 1.4 inches greater minimum ground clearance than the Acadia (8.6 vs. 7.2 inches), allowing the QX55 to travel over rougher terrain without being stopped or damaged.

The QX55 is 7.1 inches shorter than the Acadia, making the QX55 easier to handle, maneuver and park in tight spaces.

The front step up height for the QX55 is .6 inches lower than the Acadia (17.4” vs. 18”). The QX55’s rear step up height is 1.2 inches lower than the Acadia’s (17.8” vs. 19”).

The QX55 has a much larger cargo volume than the Acadia with its rear seat up (26.9 vs. 12.8 cubic feet).

A low lift-over cargo hatch design makes loading and unloading the QX55 easier. The QX55’s cargo hatch lift-over height is 29.9 inches, while the Acadia’s liftover is 32 inches.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the QX55. The Acadia doesn’t offer locking storage for small valuables.

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than GMC. J.D. Power ranks Infiniti 9th in service department satisfaction (above the industry average). With a 9% lower rating, GMC is ranked 15th.

The QX55’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 Acadia’s rear power window switches have to be held the entire time to open them fully. Only its driver’s window closes automatically.

If the windows are left open on the QX55 the driver can close them all at the outside door handle. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Acadia can only operate the windows from inside the vehicle, with the ignition on.

The QX55 has a standard locking fuel door with a remote release located convenient to the driver. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank. The Acadia doesn’t offer a locking fuel door.

The QX55 Essential/Sensory’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Acadia’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

To help drivers see further while navigating curves, the QX55 Essential/Sensory has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Acadia doesn’t offer cornering lights.
