For enhanced safety, the front and rear seat shoulder belts of the Toyota Rav4 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 Hyundai Ioniq Plug-In Hybrid doesn’t offer pretensioners for the rear seat belts.
The Rav4 Prime 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 Ioniq Plug-In 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.
Over 200 people are killed each year when backed over by motor vehicles. The Rav4 Prime XSE offers optional Parking Assist with Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Ioniq Plug-In Hybrid doesn’t offer backup collision prevention brakes.
The Rav4 Prime has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Ioniq Plug-In Hybrid doesn’t offer all-wheel drive.
The Rav4 Prime XSE offers an optional Bird’s Eye View Camera to allow the driver to see objects all around the vehicle on a screen. The Ioniq Plug-In Hybrid 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.
To help make backing out of a parking space safer, the Rav4 Prime has a standard rear 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. Rear cross-path warning costs extra on the Ioniq Plug-In Hybrid.
Both the Rav4 Prime and the Ioniq Plug-In Hybrid have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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 and rearview cameras.
The Toyota Rav4 Prime weighs 917 to 982 pounds more than the Hyundai Ioniq Plug-In Hybrid. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Rav4 Prime the rating of “Top Pick” for 2021, a rating granted to only 145 vehicles tested by the IIHS. The Ioniq Plug-In Hybrid has not been fully tested, yet.
