Compare the2024 Lexus UXVS 2023 BMW X4

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 X4 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 X4 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 X4 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 X4’s side airbags don’t have smart features and will always deploy full force.

Both the UX and the X4 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.

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 X4 has not been tested, yet.

Lexus’ powertrain warranty covers the UX 2 years and 20,000 miles longer than BMW covers the X4. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the X4 ends after only 4 years or 50,000 miles.

On the EPA test cycle the UX gets better mileage than the X4:

To lower fuel costs and make buying fuel easier, the Lexus UX uses regular unleaded gasoline. The X4 requires premium, 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 BMW X4 (5 to 7). This means the UX produces up to 8 pounds less smog-producing pollutants than the X4 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 X4 doesn’t offer a CVT.

For better maneuverability, the UX’s turning circle is 5.6 feet tighter than the X4’s (34.2 feet vs. 39.8 feet).

The Lexus UX may be more efficient, handle and accelerate better because it weighs about 700 to 800 pounds less than the BMW X4.

The UX is 10.6 inches shorter than the X4, making the UX easier to handle, maneuver and park in tight spaces.

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.

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 X4 doesn’t offer an easy entry system.

To improve rear visibility by keeping the rear window clear, the UX has a standard rear wiper. The X4 doesn’t offer a rear wiper.

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 X4 doesn’t offer headlight washers.

The UX is available in both front-wheel drive and four-wheel drive configurations. The X4 doesn’t offer a two-wheel drive configuration.
