The 530e’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The ES Series doesn’t offer pre-crash pretensioners.
A passive infrared night vision system optional on the 530e helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The ES Series doesn’t offer a night vision system.
The 530e has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the ES Series’ blind spot costs extra.
To help make backing out of a parking space safer, the 530e has a standard cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Cross-path warning costs extra on the ES Series.
Both the 530e and the ES Series have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, rearview cameras, driver alert monitors and available all wheel drive.
The BMW 530e weighs 534 to 726 pounds more than the Lexus ES Series. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
