For enhanced safety, the front and rear seat shoulder belts of the Nissan Leaf 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 Hyundai Kona Electric doesn’t offer pretensioners for the rear seat belts.
The Nissan Leaf 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.
Over 200 people are killed each year when backed over by motor vehicles. The Leaf has standard Rear 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 Leaf (except S) offers an optional Around View® Monitor 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 Leaf 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, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, available daytime running lights and driver alert monitors.
