To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the CX-30. But it costs extra on the UX.

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 UX 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.

Both the CX-30 and UX have rear cross-traffic warning, 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 UX’s Rear Cross-Traffic Alert doesn’t automatically brake.

Both the CX-30 and the UX 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 driver alert monitors.

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 UX is only a standard “Top Safety Pick” for 2024.

An engine control system that can shut down some of the engine’s cylinders helps improve the CX-30 (except Turbo)’s fuel efficiency. The UX doesn’t offer a system that can shut down part of the engine.

The CX-30 has 2.1 gallons more fuel capacity than the UX (12.7 vs. 10.6 gallons), for longer range between fill-ups.

The CX-30 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the UX; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.
