For enhanced safety, the front seat shoulder belts of the Kia Niro EV 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 Fiat 500e doesn’t offer height-adjustable 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 Niro EV are reminded to check the back seat if they opened the rear door before starting out. The 500e doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The Niro EV Wave has standard Parking Collision-Avoidance Assist that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The 500e doesn’t offer backup collision prevention brakes.
Both the Niro EV and the 500e have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, driver alert monitors and available front parking sensors.
The Kia Niro EV weighs 769 pounds more than the Fiat 500e. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
