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 Nexo doesn’t offer pretensioners for its rear seat belts.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Leaf are reminded to check the back seat if they opened the rear door before starting out. The Nexo doesn’t offer a back seat reminder.
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 Nexo doesn’t offer knee airbags.
The Leaf has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Nexo doesn’t offer a whiplash protection system.
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 Nexo doesn’t offer backup collision prevention brakes.
Both the Leaf and the Nexo 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, around view monitors and driver alert monitors.
