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 Hornet are reminded to check the back seat if they opened the rear door before starting out. The 500X doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The Hornet offers optional Rear Park-Assist with Stop that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The 500X doesn’t offer backup collision prevention brakes.
The Hornet’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the 500X and is only available on 500X Sport.
The Hornet offers an optional 360° Surround View Camera to allow the driver to see objects all around the vehicle on a screen. The 500X 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 Hornet 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 500X’s blind spot costs extra.
To help make backing out of a parking space safer, the Hornet has standard Rear Cross Traffic Alert, helping the driver avoid collisions. Fiat charges extra for Rear Cross Path Detection on the 500X, and only on the Sport.
Both the Hornet and the 500X have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras and available driver alert monitors.
The Dodge Hornet weighs 410 to 835 pounds more than the Fiat 500X. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
