For enhanced safety, the front and rear seat shoulder belts of the Mazda CX-30 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Fiat 500X doesn’t offer pretensioners for its rear seat belts.
The Mazda CX-30 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The 500X doesn’t offer a front passenger side knee airbag.
The Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 6 points, IIHS rates the Smart Brake Support in the CX-30 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-30 Turbo Premium Plus has standard Rear Smart Brake Support 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-30’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-30 Turbo Premium Plus has a standard 360° View 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-30’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-30 and the 500X have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available blind spot warning systems and rear cross-path warning.
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-30 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 101 vehicles tested by the IIHS. The 500X last would have qualified as only a standard “Top Safety Pick” in 2017.
