The A6 e-tron’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Ioniq 6 doesn’t offer pre-crash pretensioners.
The Audi A6 e-tron has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help 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 Ioniq 6 doesn’t offer knee airbags.
In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Audi A6 e-tron achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Hyundai Ioniq 6 has not been tested.
The A6 e-tron 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 Ioniq 6 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.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The A6 e-tron has Car-to-X Services, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Ioniq 6 doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
The Audi A6 e-tron offers an optional Top View Cameras and it also offers an optional rear camera washer to make backing always safe, regardless of road dirt or grime, while the Hyundai Ioniq 6 doesn’t offer a camera washer, requiring manual cleaning.
Both the A6 e-tron and the Ioniq 6 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
The Audi A6 e-tron has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2026 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, a “Good” score in the revised pedestrian crash prevention test, and a “Good” score in the revised vehicle-to-vehicle crash prevention test. The Ioniq 6 has not yet been fully evaluated by the IIHS for 2026.
