For enhanced safety, the front and rear seat shoulder belts of the Lexus RX 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 RX 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 RX 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.
Both the RX and X3 have rear cross-traffic warning, but the RX has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The X3’s Cross Traffic Warning doesn’t automatically brake.
Both the RX and the X3 have standard driver and passenger frontal airbags, front 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 around view monitors.
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, results indicate that the Lexus RX is safer than the BMW X3:
