For enhanced safety, the front and rear seat shoulder belts of the Audi A4 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 Envista doesn’t offer pretensioners for its rear seat belts.
The A4 Allroad’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Envista doesn’t offer pre-crash pretensioners.
For enhanced safety, the front seat shoulder belts of the Audi A4 Allroad are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Buick Envista doesn’t offer height-adjustable seat belts.
The Audi A4 Allroad 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 Envista doesn’t offer knee airbags.
The A4 Allroad has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Envista 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.
The A4 Allroad has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Envista doesn’t offer all-wheel drive.
The A4 Allroad Premium Plus/Prestige has a standard Top View Camera System to allow the driver to see objects all around the vehicle on a screen. The Envista only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.
Both the A4 Allroad and Envista offer rear cross-traffic warning, but the A4 Allroad with Rear Cross-Traffic Assist also has Automatic Brake Activation (automatically applies the brakes) to better prevent a collision when backing near traffic. The Envista’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the A4 Allroad and the Envista have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available blind spot warning systems.
The Audi A4 Allroad weighs 732 to 817 pounds more than the Buick Envista. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the A4 Allroad the rating of “Top Safety Pick” for 2022, a rating granted to only 174 vehicles tested by the IIHS. The Envista has not been tested, yet.
