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 Envision’s airbags don’t have smart features and will always deploy full force.
The Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 6 points, IIHS rates the Collision Mitigation Braking System in the Passport as “Superior.” The Envision scores at most only 4 points and is rated only “Advanced.”
Both the Passport and the Envision 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, 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 Envision has not been fully tested, yet.
The engine in the Passport has a single overhead cam for simplicity. The engines in the Envision have dual overhead cams, which add to the number of moving parts and the complexity of the cylinder heads.
From surveys of all its subscribers, Consumer Reports’ December 2019 Auto Issue reports that Honda vehicles are more reliable than Buick vehicles. Consumer Reports ranks Honda 6 places higher in reliability than Buick.
The Passport’s 3.5 SOHC V6 produces 83 more horsepower (280 vs. 197) and 70 lbs.-ft. more torque (262 vs. 192) than the Envision’s standard 2.5 DOHC 4-cylinder. The Passport’s 3.5 SOHC V6 produces 28 more horsepower (280 vs. 252) than the Envision Premium’s standard 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 Envision 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 Envision Premium requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.
The Passport has 2.2 gallons more fuel capacity than the Envision (19.5 vs. 17.3 gallons), for longer range between fill-ups.
The Passport 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 Envision doesn’t offer a cap-less fueling system.
The Passport stops shorter than the Envision:
60 to 0 MPH (Wet)
For better traction, the Passport has larger standard tires than the Envision (245/50R20 vs. 225/60R18). The Passport Touring/Elite’s tires are larger than the largest tires available on the Envision (265/45R20 vs. 235/50R19).
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 Envision’s standard 60 series tires. The Passport Touring/Elite’s tires have a lower 45 series profile than the Envision Premium’s 50 series tires.
For better ride, handling and brake cooling the Passport has standard 20-inch wheels. Smaller 18-inch wheels are standard on the Envision. The Envision’s largest wheels are only 19-inches.
The Passport 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 Envision doesn’t offer variable-assist power steering.
For a smoother ride and more stable handling, the Passport’s wheelbase is 2.6 inches longer than on the Envision (110.9 inches vs. 108.3 inches).
For better handling and stability, the average track (width between the wheels) on the Passport is 4.8 inches wider in the front and 4.8 inches wider in the rear than the track on the Envision.
The Passport has 15.3 cubic feet more passenger volume than the Envision (115.9 vs. 100.6).
The Passport has .1 inches more front headroom, 4.7 inches more front hip room, 5 inches more front shoulder room, 1.6 inches more rear headroom, 2.1 inches more rear legroom, 4.2 inches more rear hip room and 6.1 inches more rear shoulder room than the Envision.
The Passport has a much larger cargo volume with its rear seat up than the Envision with its rear seat up (41.2 vs. 26.9 cubic feet). The Passport has a much larger cargo volume with its rear seat folded than the Envision with its rear seat folded (77.9 vs. 57.3 cubic feet).
A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Passport. The Envision doesn’t offer locking storage for small valuables.
The Passport’s standard towing capacity is much higher than the Envision’s (3500 vs. 1500 pounds). Maximum trailer towing in the Buick Envision is only 1500 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 Envision’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 Envision can only operate the windows from inside the vehicle, with the ignition on.
The Passport’s standard speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The Envision’s standard manually variable intermittent wipers have to be constantly adjusted.
Consumer Reports rated the Passport’s headlight performance “Very Good,” a higher rating than the Envision’s headlights, which were rated “Good.”
