The Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 6 points, IIHS rates the Smart City Brake Support in the CX-5 as “Superior.” The 500X scores only 4 points and is rated only “Advanced.”
Over 200 people are killed each year when backed over by motor vehicles. The CX-5 Turbo Signature has standard Smart Brake Support-Rear that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The 500X doesn’t offer backup collision prevention brakes.
The CX-5’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 CX-5 Turbo Signature has a standard 360° Monitor 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 CX-5 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 CX-5 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 CX-5 and the 500X have standard driver and passenger frontal airbags, front side-impact 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 Mazda CX-5 weighs 478 to 551 pounds more than the Fiat 500X. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, and daytime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the CX-5 the rating of “Top Safety Pick” for 2023, a rating granted to only 98 vehicles tested by the IIHS. The 500X last would have qualified as a “Top Safety Pick” in 2017.
