The CX-30 has standard Whiplash-Reducing Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash-Reducing Headrests system moves the headrests forward to prevent neck and spine injuries. The Encore GX doesn’t offer a whiplash protection system.
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 use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The Encore GX doesn’t offer backup collision prevention brakes.

Both the CX-30 and Encore GX have Rear Cross Traffic Alert, but the CX-30 Turbo Premium Plus has Smart Braking Support - Rear Crossing (automatically applies the brakes) to better prevent a collision when backing near traffic. The Encore GX’s Rear Cross Traffic Alert doesn’t automatically brake.
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 Encore GX doesn’t offer a driver alert monitor.
Both the CX-30 and the Encore GX have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the CX-30 is 2.4% to 3.8% less likely to roll over than the Encore GX.
The Mazda CX-30 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The Encore GX is not even a standard “Top Safety Pick” for 2024.
