The e-tron GT’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.
Both the e-tron GT and Ioniq 6 have child safety locks to prevent children from opening the rear doors. The e-tron GT has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Ioniq 6’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
The Audi e-tron GT 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 Ioniq 6 doesn’t offer knee airbags.
The e-tron GT 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.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the e-tron GT. But it costs extra on the Ioniq 6.
Both the e-tron GT 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 and available around view monitors.
The Audi e-tron GT weighs 444 to 1204 pounds more than the Hyundai Ioniq 6. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
