Compare the2023 Lexus UXVS 2022 Mazda CX-30

For enhanced safety, the front and rear seat shoulder belts of the Lexus UX have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Mazda CX-30 doesn’t offer pretensioners for its rear seat belts.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the UX are reminded to check the back seat if they opened the rear door before starting out. The CX-30 doesn’t offer a back seat reminder.

Using vehicle speed sensors and seat sensors, smart airbags in the UX deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The UX’s side airbags will shut off if a child is leaning against the door. The CX-30’s side airbags don’t have smart features and will always deploy full force.

The UX has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The CX-30 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

The UX 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 and moves the vehicle back into its lane. Only the CX-30 Select/Preferred/Carbon/Turbo/Premium offers a blind spot warning system.

To help make backing out of a parking space safer, the UX 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 CX-30 Select/Preferred/Carbon/Turbo/Premium has a rear cross-path warning system.

Both the UX and the CX-30 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, 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, rearview cameras, driver alert monitors, available all wheel drive and rear parking sensors.

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, results indicate that the Lexus UX is safer than the Mazda CX-30:

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

The UX comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The CX-30’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

Lexus’ powertrain warranty covers the UX 1 year and 10,000 miles longer than Mazda covers the CX-30. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the CX-30 ends after only 5 years or 60,000 miles.

The UX’s corrosion warranty is 1 year longer than the CX-30’s (6 vs. 5 years).

The battery on the UX is in the trunk, which protects it from hot underhood temperatures that can degrade battery life. By keeping the UX’s battery 20 to 30 degrees cooler, its life is increased by years. The CX-30’s battery is in the hot engine compartment.

J.D. Power and Associates rated the UX second among small premium suvs in their 2022 Initial Quality Study. The CX-30 isn’t in the top three in its category.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Lexus vehicles are better in initial quality than Mazda vehicles. J.D. Power ranks Lexus above average in initial quality. With 23 more problems per 100 vehicles, Mazda is rated lower.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Lexus vehicles are more reliable than Mazda vehicles. J.D. Power ranks Lexus above average in long-term dependability. With 33 more problems per 100 vehicles in the first three years of ownership, Mazda is rated lower.

On the EPA test cycle the UX gets better mileage than the CX-30:

Regenerative brakes improve the UX’s fuel efficiency by converting inertia back into energy instead of wasting it. The CX-30 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the UX’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. The CX-30 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Lexus UX uses regular unleaded gasoline. The CX-30 with the 2.5 turbo 4-cylinder engine requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Lexus UX higher (7 out of 10) than the Mazda CX-30 (5 to 7). This means the UX produces up to 8 pounds less smog-producing pollutants than the CX-30 every 15,000 miles.

The UX has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The CX-30 doesn’t offer a CVT.

For better stopping power the UX’s brake rotors are larger than those on the CX-30:

The UX stops shorter than the CX-30:

For better traction, the UX has larger tires than the CX-30 (225/50R18 vs. 215/65R16).

The UX’s tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the CX-30 2.5 S’ standard 65 series tires. The UX’s tires are lower profile than the CX-30 Select/Preferred/Carbon/Turbo/Premium’s 55 series tires.

For better ride, handling and brake cooling the UX has standard 18-inch wheels. Smaller 16-inch wheels are standard on the CX-30 2.5 S.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the UX can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The CX-30 doesn’t offer run-flat tires.

For superior ride and handling, the Lexus UX has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Mazda CX-30 has a rear torsion beam axle, with a semi-independent rear suspension.

The UX has standard front and rear gas-charged shocks for better control over choppy roads. The CX-30’s suspension doesn’t offer gas-charged shocks.

The UX has standard front and rear stabilizer bars, which help keep the UX flat and controlled during cornering. The CX-30’s suspension doesn’t offer a rear stabilizer bar.

The UX 250h F Sport Handling AWD handles at .80 G’s, while the CX-30 Premium pulls only .79 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the UX’s turning circle is .6 feet tighter than the CX-30’s (34.2 feet vs. 34.8 feet).

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the UX. The CX-30 doesn’t offer locking storage for small valuables.

To make loading groceries and cargo easier when your hands are full, the UX’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The CX-30 doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

J.D. Power and Associates surveys of service recipients show that Lexus service is better than Mazda. J.D. Power ranks Lexus first in service department satisfaction. With a 41% lower rating, Mazda is ranked 11th.

The UX’s optional easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The CX-30 doesn’t offer an easy entry system.

If the windows are left open on the UX the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (This window function must be activated by your Lexus service department.) The driver of the CX-30 can only operate the windows from inside the vehicle, with the ignition on.

To improve rear visibility by keeping the rear window clear, the UX has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the CX-30 only has an intermittent setting, so in a hard rain visibility isn’t as good.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The UX offers available headlight washers to keep headlight output high. The CX-30 doesn’t offer headlight washers.

The UX’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Mazda only offers heated mirrors on the CX-30 Carbon/Turbo.

Optional air-conditioned seats in the UX keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The CX-30 doesn’t offer air-conditioned seats.

The UX has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning is only available on the CX-30 Select/Preferred/Carbon/Turbo/Premium.

The UX is available in both front-wheel drive and four-wheel drive configurations. The CX-30 doesn’t offer a two-wheel drive configuration.
