For enhanced safety, the front and second-row seat shoulder belts of the Lexus LX have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The BMW X6 doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Lexus LX 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 X6 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 LX are reminded to check the back seat if they opened the rear door before starting out. The X6 doesn’t offer a back seat reminder.
Both the LX and X6 have rear cross-traffic warning, but the LX has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The X6’s Cross Traffic Warning doesn’t automatically brake.
Both the LX and the X6 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, all wheel drive, 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 and driver alert monitors.
The Lexus LX weighs 540 to 1090 pounds more than the BMW X6. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
