For enhanced safety, the front seat shoulder belts of the Acura RDX 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 Acura RDX 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 RDX has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Envista doesn’t offer all-wheel drive.
The RDX Advance has a standard Surround-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.
To help make backing out of a parking space safer, the RDX has standard Rear Cross Traffic Monitor, helping the driver avoid collisions. Buick charges extra for Rear Cross Traffic Alert on the Envista.
Both the RDX and the Envista have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems and rearview cameras.
The Acura RDX weighs 899 to 1028 pounds more than the Buick Envista. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
The Acura RDX achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Envista has not yet been evaluated by the IIHS for 2024.
