Compare the2023 Lexus UXVS 2023 Mazda CX-50

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-50 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-50 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-50’s side airbags don’t have smart features and will always deploy full force.

The UX has standard Whiplash Injury Lessening Front Seatbacks, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Injury Lessening Front Seatbacks system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The CX-50 doesn’t offer a whiplash protection system.

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-50 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-50 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, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available all wheel drive and rear parking sensors.

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Lexus UX is safer than the CX-50:

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the UX its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 29 vehicles tested by the IIHS. The CX-50 is only a standard “Top Safety Pick” for 2023.

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-50’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-50. 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-50 ends after only 5 years or 60,000 miles.

The UX’s corrosion warranty is 1 year longer than the CX-50’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-50’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-50 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.

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.

From surveys of all its subscribers, Consumer Reports’ January 2023 Auto Issue reports that Lexus vehicles are more reliable than Mazda vehicles. Consumer Reports ranks Lexus second in overall reliability. Mazda is ranked fourth.

As tested in Consumer Reports the Lexus UX is faster than the Mazda CX-50 4 cyl.:

On the EPA test cycle the UX gets better mileage than the CX-50:

Regenerative brakes improve the UX’s fuel efficiency by converting inertia back into energy instead of wasting it. The CX-50 doesn’t offer a regenerative braking system.

To lower fuel costs and make buying fuel easier, the Lexus UX uses regular unleaded gasoline. The CX-50 with the 2.5 turbo 4-cylinder engine requires premium for maximum efficiency, which can cost on average about 82.8 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-50 (3 to 7). This means the UX produces up to 24.5 pounds less smog-producing pollutants than the CX-50 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-50 doesn’t offer a CVT.

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-50’s standard 65 series tires.

For better ride, handling and brake cooling the UX has standard 18-inch wheels. Smaller 17-inch wheels are standard on the CX-50.

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-50 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-50 has a rear torsion beam axle, with a semi-independent rear suspension.

The UX has standard front and rear stabilizer bars, which help keep the UX flat and controlled during cornering. The CX-50’s suspension doesn’t offer a rear stabilizer bar.

For better maneuverability, the UX’s turning circle is 1.8 feet tighter than the CX-50’s (34.2 feet vs. 36 feet).

The Lexus UX may be more efficient, handle and accelerate better because it weighs about 200 to 300 pounds less than the Mazda CX-50.

The UX is 8.8 inches shorter than the CX-50, making the UX easier to handle, maneuver and park in tight spaces.

The UX has .4 inches more front legroom, .2 inches more front hip room and .2 inches more rear hip room than the CX-50.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the UX. The CX-50 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-50 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 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The CX-50 doesn’t offer a remote starting system.

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-50 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-50 can only close the windows from inside the vehicle, with the ignition on.

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-50 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-50 Preferred/Premium/Turbo.

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-50 Select/Preferred/Premium/Turbo.

Both the UX and the CX-50 offer rear vents. For greater rear passenger comfort, the UX has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The CX-50 doesn’t offer rear air conditioning vents, only heat vents.

The UX is available in both front-wheel drive and four-wheel drive configurations. The CX-50 doesn’t offer a two-wheel drive configuration.

Consumer Reports® recommends both the Lexus UX and the Mazda CX-50, based on reliability, safety and performance.
