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 uses rear sensors to monitor and automatically apply the brakes to prevent a rear 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 Trekking/Sport/Trekking Plus.
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 which 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 a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Only the 500X Trekking/Sport/Trekking Plus offers a rear cross-path warning system and it costs extra.
The CX-5 Turbo Signature’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The 500X doesn’t offer a driver alert monitor.
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, daytime running lights and rearview cameras.
The Mazda CX-5 weighs 423 to 562 pounds more than the Fiat 500X. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the CX-5 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 93 vehicles tested by the IIHS. The 500X last would have qualified as only a standard “Top Safety Pick” in 2017.
