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 National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Mazda CX-30 is safer than the Lexus UX:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

The Insurance Institute for Highway Safety does 40 MPH moderate front offset crash tests on new cars. In this updated test, results indicate that the CX-30 is much safer than the UX:

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Mazda CX-30 is safer than the Lexus UX:

	CX-30	UX

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.

Warranty

There are over 2 times as many Mazda dealers as there are Lexus dealers, which makes it much easier should you ever need service under the CX-30’s warranty.

Engine

The CX-30’s standard 2.5 DOHC 4-cylinder produces 10 more horsepower (191 vs. 181) than the UX’s 2.0 DOHC 4-cylinder hybrid. The CX-30’s optional 2.5 turbo 4-cylinder produces 69 more horsepower (250 vs. 181) than the UX’s 2.0 DOHC 4-cylinder hybrid.

As tested in Motor Trend the Mazda CX-30 4 cyl. is faster than the Lexus UX:

	CX-30	UX
Zero to 60 MPH	7.8 sec	8.3 sec
Quarter Mile	16 sec	16.3 sec
Speed in 1/4 Mile	88.3 MPH	87.3 MPH

Fuel Economy and Range

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.

Brakes and Stopping

The CX-30 stops shorter than the UX:

	CX-30	UX
60 to 0 MPH	119 feet	128 feet	Motor Trend

Tires and Wheels

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.

Suspension and Handling

The CX-30 2.5 S Premium handles at .83 G’s, while the UX 250h F Sport Handling AWD pulls only .80 G’s of cornering force in a Motor Trend skidpad test.

The CX-30 2.5 S Premium executes Motor Trend’s “Figure Eight” maneuver quicker than the UX 250h F Sport Handling AWD (27.4 seconds @ .62 average G’s vs. 28.1 seconds @ .62 average G’s).

Chassis

The CX-30 is 4 inches shorter than the UX, making the CX-30 easier to handle, maneuver and park in tight spaces.

Passenger Space

The CX-30 has 3.7 cubic feet more passenger volume than the UX (94.1 vs. 90.4).

The CX-30 has .9 inches more front headroom, .8 inches more front hip room, .6 inches more front shoulder room, 2 inches more rear headroom, 3.2 inches more rear legroom, .9 inches more rear hip room and .7 inches more rear shoulder room than the UX.

Cargo Capacity

The CX-30 has a much larger cargo volume with its rear seat up than the UX (20.2 vs. 17.1 cubic feet).

Economic Advantages

Insurance will cost less for the CX-30 owner. The Complete Car Cost Guide estimates that insurance for the CX-30 will cost $395 to $2500 less than the UX over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Mazda CX-30 will be $2288 to $5890 less than for the Lexus UX.

Recommendations

Consumer Reports® recommends both the Mazda CX-30 and the Lexus UX, based on reliability, safety and performance.

The Mazda CX-30 outsold the Lexus UX by almost seven to one during 2023.
