The Corolla has standard Whiplash Injury Lessening Seats, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Injury Lessening Seats system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The Sonata doesn’t offer a whiplash protection system.
The Corolla 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 Sonata 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.
Both the Corolla and the Sonata have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, driver alert monitors, available blind spot warning systems and rear cross-path warning.
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 Corolla the rating of “Top Safety Pick” for 2023, a rating granted to only 98 vehicles tested by the IIHS. The Sonata has not been tested, yet.
