For enhanced safety, the front and rear seat shoulder belts of the Kia Niro EV have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Fiat 500e doesn’t offer pretensioners for its rear seat belts.
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.
The Niro EV has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the 500e’s blind spot costs extra.
To help make backing out of a parking space safer, the Niro EV has standard Rear Cross-Traffic Collision Warning and Rear Cross-Traffic Collision-Avoidance Assist automatically engages the brakes to help avoid a collision. Fiat charges extra for Rear Cross Path Detection on the 500e and the 500e’s Rear Cross Path Detection does not include automatic braking.
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 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 to 851 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.
