The Toyota Corolla Hybrid has a standard driver’s knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelt or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Clarity Plug-In Hybrid doesn’t offer a front passenger side knee airbag.
The Corolla Hybrid 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 Clarity Plug-In Hybrid doesn’t offer a whiplash protection system.
The Corolla Hybrid 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 Clarity 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.
To help make backing out of a parking space safer, the Corolla Hybrid’s optional cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Clarity Plug-In Hybrid doesn’t offer a cross-path warning system.
The Corolla Hybrid’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Clarity Plug-In Hybrid doesn’t offer a driver alert monitor.
Both the Corolla Hybrid and the Clarity Plug-In Hybrid have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, rearview cameras and available blind spot warning systems.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the Corolla Hybrid the rating of “Top Pick” for 2017, a rating granted to only 213 vehicles tested by the IIHS. The Clarity Plug-In Hybrid has not been tested, yet.
