For enhanced safety, the front seat shoulder belts of the Hyundai Nexo 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.
The Nexo Limited has a standard Surround View Monitor to allow the driver to see objects all around the vehicle on a screen. The 500e only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The Nexo 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 and moves the vehicle back into its lane. A system to reveal vehicles in the 500e’s blind spot costs extra.
To help make backing out of a parking space safer, the Nexo 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 Nexo and the 500e have standard driver and passenger frontal airbags, front side-impact 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 and driver alert monitors.
The Hyundai Nexo weighs 1038 to 1165 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.
