The EQE Sedan’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 Mercedes EQE Sedan has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps 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 EQE Sedan has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Ioniq 6 doesn’t offer front seat center airbags.
The EQE Sedan’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The Ioniq 6 doesn’t offer a whiplash protection system.
The EQE Sedan has a standard Post Collision Brake, 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 EQE Sedan has Car-to-X Communication, 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.
Both the EQE Sedan and the Ioniq 6 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear 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 driver alert monitors.
The Mercedes EQE Sedan weighs 719 to 1599 pounds more than the Hyundai Ioniq 6. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
