For enhanced safety, the front and rear seat shoulder belts of the Hyundai Ioniq 6 N 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 BMW i5 doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Hyundai Ioniq 6 N 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 BMW i5 doesn’t offer height-adjustable seat belts.
Both the Ioniq 6 N and i5 have child safety locks to prevent children from opening the rear doors. The Ioniq 6 N 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 i5’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.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Ioniq 6 N. But it costs extra on the i5.
Both the Ioniq 6 N and the i5 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, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.
