For enhanced safety, the front and rear seat shoulder belts of the Audi Allroad 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 Buick Envision doesn’t offer pretensioners for the rear seat belts.
The Allroad’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Envision doesn’t offer pre-crash pretensioners.
The Allroad has a standard Audi Backguard System, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Audi Backguard System moves the headrests forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The Envision doesn’t offer a whiplash protection system.
The Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 6 points, IIHS rates the Audi Pre Sense City in the Allroad as “Superior.” The Envision scores at most only 4 points and is rated only “Advanced.”
The Allroad has standard Secondary Collision Brake Assist, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Envision doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Allroad. But it costs extra on the Envision.
Both the Allroad and the Envision have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height-adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.
The Allroad’s corrosion warranty is 6 years longer than the Envision’s (12 vs. 6 years).
The Audi Allroad’s engine uses a cast iron block for durability, while the Envision’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.
From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Buick vehicles. Consumer Reports ranks Audi 12 places higher in reliability than Buick.
The Allroad’s 2.0 turbo 4 cyl. produces 51 more horsepower (248 vs. 197) and 81 lbs.-ft. more torque (273 vs. 192) than the Envision’s standard 2.5 DOHC 4 cyl.
The Allroad offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Envision doesn’t offer an SMG or a conventional manual transmission.
The Allroad’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Envision doesn’t offer launch control.
For better stopping power the Allroad’s brake rotors are larger than those on the Envision:
The Allroad’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Envision are solid, not vented.
The Allroad stops shorter than the Envision:
60 to 0 MPH
For better traction, the Allroad has larger tires than the Envision (245/45R18 vs. 225/60R18). The Allroad’s tires are larger than the largest tires available on the Envision (245/45R18 vs. 235/50R19).
The Allroad’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Envision’s standard 60 series tires. The Allroad’s tires are lower profile than the Envision Premium’s 50 series tires.
The Allroad has a standard 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. The Envision’s suspension doesn’t offer adjustable shock absorbers.
The Allroad 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 Allroad’s wheelbase is 2.6 inches longer than on the Envision (110.9 inches vs. 108.3 inches).
The Allroad Premium Plus executes Motor Trend’s “Figure-Eight” maneuver 1.2 seconds quicker than the Envision Premium (26.3 seconds @ .69 average G’s vs. 27.5 seconds @ .63 average G’s).
The Allroad is 8 inches shorter in height than the Envision, making the Allroad much easier to wash and garage and drive (lower center of gravity).
The Allroad has a larger cargo volume with its rear seat folded than the Envision with its rear seat folded (58.5 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 Allroad. The Envision doesn’t offer locking storage for small valuables.
The engine in the Allroad is mounted longitudinally (North-South), instead of sideways, as in the Envision. This makes it easier to service and maintain, because the accessory belts are in front.
J.D. Power and Associates surveys of service recipients show that Audi service is better than Buick. J.D. Power ranks Audi third in service department satisfaction. With a 21% lower rating, Buick is ranked 9th.
The Allroad’s front and rear power windows all 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 passenger windows don’t close automatically.
If the windows are left open on the Allroad the driver can close them all at the outside door handle. On a hot day the driver can also lower the windows the same way. The driver of the Envision can only operate the windows from inside the vehicle, with the ignition on.
The Allroad 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 Envision doesn’t offer a locking fuel door.
The Allroad’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 Envision’s standard manually variable intermittent wipers have to be constantly adjusted.
Heated windshield washer nozzles are standard on the Allroad to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Envision doesn’t offer heated windshield washer nozzles.
In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Allroad has standard headlight washers to keep headlight output high. The Envision doesn’t offer headlight washers.
To help drivers avoid possible obstacles, the Allroad has standard cornering lights to illuminate around corners when the turn signals are activated. The Envision doesn’t offer cornering lights.
