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 BMW X3 doesn’t offer pretensioners for its rear seat belts.

For enhanced safety, the front seat shoulder belts of the Lexus UX are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW X3 doesn’t offer height-adjustable 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 X3 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 X3’s side airbags don’t have smart features and will always deploy full force.

Both the UX and the X3 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, 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 and into a post at 20 MPH, results indicate that the Lexus UX is safer than the BMW X3:

	UX	X3
	Front Seat
STARS	5 Stars	5 Stars
HIC	52	64
Abdominal Force	149 lbs.	153 lbs.
	Rear Seat
STARS	5 Stars	5 Stars
HIC	96	133
Hip Force	633 lbs.	794 lbs.
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	12 inches	13 inches

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

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the UX is 3.1% to 3.2% less likely to roll over than the X3.

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 X3 has not been fully tested, yet.

Warranty

Lexus’ powertrain warranty covers the UX 2 years and 20,000 miles longer than BMW covers the X3. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the X3 ends after only 4 years or 50,000 miles.

Reliability

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 X3’s battery is in the hot engine compartment.

J.D. Power and Associates rated the UX second among small premium suvs in their 2023 Initial Quality Study. The X3 isn’t in the top three in its category.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Lexus vehicles are better in initial quality than BMW vehicles. J.D. Power ranks Lexus above average in initial quality. With 21 more problems per 100 vehicles, BMW 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 BMW 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, BMW is rated lower.

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

Fuel Economy and Range

On the EPA test cycle the UX gets better mileage than the X3:

			MPG
UX
	FWD	2.0 4-cyl. Hybrid	43 city/41 hwy
	AWD	2.0 4-cyl. Hybrid	41 city/38 hwy
X3
	RWD	2.0 turbo 4-cyl.	23 city/29 hwy
	AWD	2.0 turbo 4-cyl.	21 city/28 hwy
		3.0 turbo 6-cyl. Hybrid	21 city/26 hwy

To lower fuel costs and make buying fuel easier, the Lexus UX uses regular unleaded gasoline. The X3 requires premium, which can cost on average about 82.8 cents more per gallon.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Lexus UX higher (7 out of 10) than the BMW X3 (5 to 7). This means the UX produces up to 8 pounds less smog-producing pollutants than the X3 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 X3 doesn’t offer a CVT.

Suspension and Handling

For better maneuverability, the UX’s turning circle is 5.2 feet tighter than the X3’s (34.2 feet vs. 39.4 feet).

Chassis

The Lexus UX may be more efficient, handle and accelerate better because it weighs about 600 to 800 pounds less than the BMW X3.

The UX is 8.9 inches shorter than the X3, making the UX easier to handle, maneuver and park in tight spaces.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Lexus service is better than BMW. J.D. Power ranks Lexus first in service department satisfaction. With a 31% lower rating, BMW is ranked 7th.

Ergonomics

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 X3 doesn’t offer an easy entry system.

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 X3 only has an intermittent setting, so in a hard rain visibility isn’t as good.

Consumer Reports rated the UX’s headlight performance “Good,” a higher rating than the X3’s headlights, which were rated “Fair.”

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 X3 doesn’t offer headlight washers.

Recommendations

Consumer Reports® recommends both the Lexus UX and the BMW X3, based on reliability, safety and performance.
