For enhanced safety, the front and rear seat shoulder belts of the Toyota Prius 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 Hyundai Elantra Hybrid doesn’t offer pretensioners for its rear seat belts.
The Prius has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Elantra Hybrid doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
The Prius has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Elantra Hybrid doesn’t offer all-wheel drive.
The Prius Limited offers an optional Panoramic View Monitor to allow the driver to see objects all around the vehicle on a screen. The Elantra Hybrid only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.
Both the Prius and the Elantra Hybrid have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, 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 its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 43 vehicles tested by the IIHS. The Elantra Hybrid was last a “Top Safety Pick Plus” in 2019 but no longer qualifies.
