For enhanced safety, the front and rear seat shoulder belts of the Toyota bZ4X have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Hyundai Kona Electric doesn’t offer pretensioners for its rear seat belts.
The Toyota bZ4X 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 bZ4X has standard post collision braking, 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 bZ4X has standard Automatic Braking 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 bZ4X has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Kona Electric doesn’t offer all-wheel drive.
When descending a steep, off-road slope, the bZ4X AWD’s standard Downhill Assist Control allows you to creep down safely. The Kona Electric doesn’t offer Downhill Assist Control.
The bZ4X Limited has a standard Bird’s Eye View Camera 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 bZ4X and the Kona Electric have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, 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 Toyota bZ4X weighs 430 to 749 pounds more than the Hyundai Kona Electric. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
