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 Sonata 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 Sonata 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 Sonata Hybrid doesn’t offer all-wheel drive.
Both the Prius and the Sonata Hybrid have standard driver and passenger frontal airbags, front and rear 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, driver alert monitors and available around view monitors.
The Insurance Institute for Highway Safety does 40 MPH moderate front offset crash tests on new cars. In this updated test, results indicate that the Prius is much safer than the Sonata Hybrid:

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Toyota Prius is safer than the Sonata Hybrid:

The Toyota Prius has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned an “Acceptable” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The Sonata Hybrid was last only a “Top Safety Pick” in 2023 but no longer qualifies.
