Compare the2025 Lexus UXVS 2025 Mazda CX-30

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.

Both the UX and the CX-30 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, 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.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the UX’s reliability 17 points higher than the CX-30.

J.D. Power and Associates rated the UX first among small premium suvs in their 2024 Initial Quality Study. The CX-30 isn’t in the top three in its category.

The UX’s 2.0 DOHC 4-cylinder hybrid produces 5 more horsepower (196 vs. 191) than the CX-30’s standard 2.5 DOHC 4-cylinder.

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 on average about 84.9 cents more per gallon.

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/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 offers an available driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The CX-30’s suspension doesn’t offer adjustable shock absorbers.

The UX AWD handles at .80 G’s, while the CX-30 2.5 S 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 36% lower rating, Mazda is ranked 14th.

The UX F Sport Handling’s standard easy entry system raises the steering wheel and 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.

The UX’s standard Smart Access allow you to unlock the doors from either front door handle, unlock the cargo door, and start the engine, all without removing the key from the pocket or purse. Pushbutton Start standard on the CX-30 only offers hands-free access for the ignition, none to unlock the vehicle. Pushbutton Start is not available on the CX-30 Select/Preferred/Carbon/Premium.

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 Select/Preferred/Carbon/Premium.

Standard air-conditioned seats in the UX Premium/F Sport 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.

The UX will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the UX will retain 58.35% to 60.33% of its original price after five years, while the CX-30 only retains 54.31% to 55.58%.

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