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 X1 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 X1 doesn’t offer height-adjustable seat belts.
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 X1’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 X1 doesn’t offer a whiplash protection system.
Both the UX and the X1 have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, 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.
