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-3 doesn’t offer pretensioners for the rear seat belts.

The Lexus UX has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The CX-3 doesn’t offer knee airbags.

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-3’s 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-3 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.

Over 200 people are killed each year when backed over by motor vehicles. The UX offers optional Parking Support Brake that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The CX-3 doesn’t offer backup collision prevention brakes.

The UX offers optional Intuitive Parking Assist to help warn the driver about vehicles, pedestrians or other obstacles behind or in front of their vehicle. The CX-3 doesn’t offer a front parking aid.

The UX’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The CX-3 doesn’t offer a driver alert monitor.

Compared to metal, the UX’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Mazda CX-3 has a metal gas tank.

Both the UX and the CX-3 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, 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 and rear cross-path warning.

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 Lexus UX is safer than the Mazda CX-3:

	UX	CX-3
	Front Seat
STARS	5 Stars	5 Stars
HIC	52	183
Chest Movement	.8 inches	.8 inches
Abdominal Force	149 G’s	199 G’s
Hip Force	323 lbs.	334 lbs.
	Rear Seat
STARS	5 Stars	5 Stars
HIC	96	241
Spine Acceleration	46 G’s	85 G’s
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	12 inches	14 inches

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

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the UX its highest rating: “Top Pick Plus” for 2019, a rating granted to only 105 vehicles tested by the IIHS. The CX-3 is only a standard “Top Pick” for 2019.

Warranty

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-3’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-3. 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-3 ends after only 5 years or 60,000 miles.

The UX’s corrosion warranty is 1 year longer than the CX-3’s (6 vs. 5 years).

Reliability

J.D. Power and Associates rated the UX first among small premium suvs in their 2021 Initial Quality Study. The CX-3 isn’t in the top three in its category.

J.D. Power and Associates’ 2021 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 third in initial quality, above the industry average. With 33 more problems per 100 vehicles, Mazda is ranked 23rd, below the industry average.

J.D. Power and Associates’ 2021 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 first in reliability, above the industry average. With 40 more problems per 100 vehicles, Mazda is ranked 14th.

Engine

The UX 200’s standard 2.0 DOHC 4-cylinder produces 21 more horsepower (169 vs. 148) and 5 lbs.-ft. more torque (151 vs. 146) than the CX-3’s 2.0 DOHC 4-cylinder. The UX 250h’s standard 2.0 DOHC 4-cylinder hybrid produces 33 more horsepower (181 vs. 148) than the CX-3’s 2.0 DOHC 4-cylinder.

As tested in Motor Trend the Lexus UX is faster than the Mazda CX-3:

	UX 200	UX 250h	CX-3
Zero to 60 MPH	8.5 sec	8.3 sec	8.6 sec
Quarter Mile	16.5 sec	16.3 sec	16.6 sec
Speed in 1/4 Mile	85.6 MPH	87.3 MPH	83 MPH

Fuel Economy and Range

On the EPA test cycle the UX gets better mileage than the CX-3:

			MPG
UX
	FWD	2.0 DOHC 4-cyl.	29 city/37 hwy
	AWD	2.0 4-cyl. Hybrid	41 city/38 hwy
CX-3
	FWD	2.0 DOHC 4-cyl.	29 city/34 hwy
	AWD	2.0 DOHC 4-cyl.	27 city/32 hwy

Regenerative brakes improve the UX Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The CX-3 doesn’t offer a regenerative braking system.

In heavy traffic or at stop lights the UX Hybrid’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-3 doesn’t offer an automatic engine start/stop system.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Lexus UX higher (6 to 7 out of 10) than the Mazda CX-3 (3 to 7). This means the UX produces up to 24.5 pounds less smog-producing pollutants than the CX-3 every 15,000 miles.

Transmission

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-3 doesn’t offer a CVT.

Brakes and Stopping

For better stopping power the UX’s brake rotors are larger than those on the CX-3:

	UX	CX-3	CX-3 AWD
Front Rotors	12 inches	11 inches	11.6 inches

The UX stops much shorter than the CX-3:

	UX	CX-3
70 to 0 MPH	171 feet	181 feet	Car and Driver
60 to 0 MPH (Wet)	143 feet	148 feet	Consumer Reports

Tires and Wheels

For better traction, the UX has larger tires than the CX-3 (225/50R18 vs. 215/60R16).

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-3’s standard 60 series tires.

For better ride, handling and brake cooling the UX has standard 18-inch wheels. Only 16-inch wheels are available on the CX-3.

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-3 doesn’t offer run-flat tires.

Suspension and Handling

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-3 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-3’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-3’s suspension doesn’t offer a rear stabilizer bar.

For a smoother ride and more stable handling, the UX’s wheelbase is 2.7 inches longer than on the CX-3 (103.9 inches vs. 101.2 inches).

For better handling and stability, the track (width between the wheels) on the UX is 1 inch wider in the front and 1.1 inches wider in the rear than on the CX-3.

For better maneuverability, the UX’s turning circle is .6 feet tighter than the CX-3’s (34.2 feet vs. 34.8 feet).

Passenger Space

The UX has 2.8 cubic feet more passenger volume than the CX-3 (90.4 vs. 87.6).

The UX has .3 inches more front legroom, 1.5 inches more front hip room, 1.5 inches more front shoulder room, 3.3 inches more rear hip room and 2.5 inches more rear shoulder room than the CX-3.

Cargo Capacity

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the UX. The CX-3 doesn’t offer locking storage for small valuables.

To make loading and unloading groceries and cargo easier when your hands are full, the UX’s power liftgate can be opened or closed just by kicking your foot under the back bumper, leaving your hands completely free. The CX-3 doesn’t offer a power or hands-free opening liftgate.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Lexus service is better than Mazda. J.D. Power ranks Lexus second in service department satisfaction. With a 53% lower rating, Mazda is ranked 23rd.

Ergonomics

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-3 doesn’t offer a remote starting system.

When three different drivers share the UX (except Base), the optional memory system makes it convenient for all three. Each setting activates different, customized memories for the driver’s seat position, steering wheel position and outside mirror angle. The CX-3 doesn’t offer a memory system.

The UX’s optional 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-3 doesn’t offer an easy entry system.

The UX’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The CX-3’s passenger windows don’t open or close automatically.

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-3 can only operate the windows from inside the vehicle, with the ignition on.

Smart Access standard on the UX allows you to unlock the driver’s door, cargo door and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Mazda CX-3’s Pushbutton Start doesn’t unlock the doors or the cargo door.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The UX’s available headlights were rated “Good” by the IIHS, while the CX-3’s headlights are rated “Acceptable.”

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-3 doesn’t offer headlight washers.

The UX’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. The CX-3 doesn’t offer heated side mirrors.

When the UX with available tilt-down mirrors is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The CX-3’s mirrors don’t automatically adjust for backing.

The UX’s optional rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The CX-3 offers an automatic rear view mirror, but its side mirrors don’t dim.

The UX offers optional heated front seats, which keep the driver and front passenger extremely comfortable in the winter. Heated seats aren’t available in the CX-3.

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-3 doesn’t offer air-conditioned seats.

On extremely cold winter days, the UX’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The CX-3 doesn’t offer a heated steering wheel.

The UX’s 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. The CX-3 doesn’t offer dual zone air conditioning.

Both the UX and the CX-3 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-3 doesn’t offer rear air conditioning vents, only heat vents.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Lexus UX offers an optional wireless phone charging system (Qi) in the center console. The CX-3 doesn’t offer wireless personal charging.
