Using vehicle speed sensors and seat sensors, smart airbags in the Passport deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The Passport’s side airbags will shut off if a child is leaning against the door. The Acadia’s airbags don’t have smart features and will always deploy full force.
Both the Passport and the Acadia have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, 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, blind spot warning systems, rear parking sensors and rear cross-path warning.
For its top level performance in IIHS driver-side small overlap frontal, moderate overlap frontal, side impact, rear impact and roof-crush tests, its standard front crash prevention system, its “Acceptable” rating in the new passenger-side small overlap crash test, and its headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the Passport the rating of “Top Pick” for 2019, a rating granted to only 106 vehicles tested by the IIHS. The Acadia was last qualified as a “Top Pick” in 2017.
The Passport’s corrosion warranty is unlimited miles longer than the Acadia’s (unlimited vs. 100,000 miles).
The engine in the Passport has a single overhead cam for simplicity. The engines in the Acadia have dual overhead cams, which add to the number of moving parts and the complexity of the cylinder heads.
J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Honda vehicles are more reliable than GMC vehicles. J.D. Power ranks Honda 16th in reliability. With 15 more problems per 100 vehicles, GMC is ranked 22nd.
From surveys of all its subscribers, Consumer Reports’ December 2019 Auto Issue reports that Honda vehicles are more reliable than GMC vehicles. Consumer Reports ranks Honda 10 places higher in reliability than GMC.
The Passport’s 3.5 SOHC V6 produces 87 more horsepower (280 vs. 193) and 74 lbs.-ft. more torque (262 vs. 188) than the Acadia’s standard 2.5 DOHC 4-cylinder. The Passport’s 3.5 SOHC V6 produces 50 more horsepower (280 vs. 230) and 4 lbs.-ft. more torque (262 vs. 258) than the Acadia’s optional 2.0 turbo 4-cylinder.
An engine control system that can shut down some of the engine’s cylinders helps improve the Passport’s fuel efficiency. The Acadia doesn’t offer a system that can shut down part of the engine.
To lower fuel costs and make buying fuel easier, the Honda Passport uses regular unleaded gasoline. The Acadia with the 2.0 turbo 4-cylinder engine requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.
For better traction, the Passport has larger standard tires than the Acadia (245/50R20 vs. 235/65R18). The Passport Touring/Elite’s tires are larger than the largest tires available on the Acadia (265/45R20 vs. 255/65R17).
The Passport Sport/EX-L’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Acadia’s standard 65 series tires. The Passport Touring/Elite’s tires have a lower 45 series profile than the Acadia’s optional 55 series tires.
For better ride, handling and brake cooling the Passport has standard 20-inch wheels. Smaller 17-inch wheels are standard on the Acadia.
For better handling and stability, the average track (width between the wheels) on the Passport is 2.3 inches wider in the front and 2.3 inches wider in the rear than the track on the Acadia.
For greater off-road capability the Passport has a greater minimum ground clearance than the Acadia (8.1 vs. 7.2 inches), allowing the Passport to travel over rougher terrain without being stopped or damaged. The Passport’s minimum ground clearance is .3 inch higher than on the Acadia All Terrain (8.1 vs. 7.8 inches).
A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Passport. The Acadia doesn’t offer locking storage for small valuables.
The Passport’s standard towing capacity is much higher than the Acadia’s (3500 vs. 1000 pounds). Maximum trailer towing in the GMC Acadia is only 4000 pounds. The Passport AWD offers up to a 5000 lbs. towing capacity.
The Passport’s front power windows 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 Acadia’s front passenger window doesn’t close automatically.
If the windows are left open on the Passport 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 Acadia can only operate the windows from inside the vehicle, with the ignition on.
The Passport Elite’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.
The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The Passport’s headlights were rated “Acceptable” by the IIHS, while the Acadia’s headlights are rated “Marginal” to “Poor.”
