The i4’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Kona Electric doesn’t offer pre-crash pretensioners.
The BMW i4 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 Kona Electric doesn’t offer knee airbags.
The i4 has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Kona Electric 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.
Over 200 people are killed each year when backed over by motor vehicles. The i4 offers optional Active Park Distance Control that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Kona Electric doesn’t offer backup collision prevention brakes.
The i4 M50 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Kona Electric doesn’t offer all-wheel drive.
The i4 offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The Kona Electric 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.
Both the i4 and the Kona Electric 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, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.
The BMW i4 weighs 829 to 1303 pounds more than the Hyundai Kona Electric. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
