For enhanced safety, the front and rear seat shoulder belts of the Lexus LS 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 530e doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Lexus LS 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 530e doesn’t offer height-adjustable seat belts.
The LS offers an optional Panoramic View Camera to allow the driver to see objects all around the vehicle on a screen. The 530e only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
Both the LS and 530e have rear cross-traffic warning, but the LS has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The 530e’s Cross Traffic Warning doesn’t automatically brake.
Both the LS and the 530e 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 and available all wheel drive.
