For enhanced safety, the front and rear seat shoulder belts of the Toyota Prius Prime 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 Toyota Prius Prime 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.
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 Prius Prime are reminded to check the back seat if they opened the rear door before starting out. The 530e doesn’t offer a back seat reminder.
The Prius Prime XSE Premium offers an optional Panoramic View Monitor 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 Prius Prime and 530e have rear cross-traffic warning, but the Prius Prime offers optional 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 Prius Prime and the 530e have standard driver and passenger frontal airbags, front side-impact 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 and driver alert monitors.
For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Prius Prime the rating of “Top Safety Pick Plus” for 2023, a rating granted to only 36 vehicles tested by the IIHS. The 530e has not been fully tested, yet.
