For enhanced safety, the front and rear seat shoulder belts of the Lexus ES 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 i5 doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Lexus ES 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 i5 doesn’t offer height-adjustable seat belts.
Both the ES and the i5 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 around view monitors.
For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, and daytime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the ES the rating of “Top Safety Pick” for 2023, a rating granted to only 98 vehicles tested by the IIHS. The i5 has not been tested, yet.
