With its standard Toyota Safety Sense 3.0 with Pre-Collision, the Toyota Prius Plug-In Hybrid is better at preventing collisions with pedestrians than the Hyundai Ioniq 5, according to the Insurance Institute for Highway Safety:

The Prius Plug-In 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 Ioniq 5 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 Prius Plug-In Hybrid and the Ioniq 5 have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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 National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Toyota Prius Plug-In Hybrid is safer than the Hyundai Ioniq 5:

	Prius Plug-In Hybrid	Ioniq 5
	Passenger
STARS	5 Stars	4 Stars

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Toyota Prius Plug-In Hybrid is safer than the Hyundai Ioniq 5:

	Prius Plug-In Hybrid	Ioniq 5
	Rear Seat

Spine Acceleration	42 G’s	60 G’s
Hip Force	612 lbs.	741 lbs.

The Toyota Prius Plug-In Hybrid may be more efficient, handle and accelerate better because it weighs about 700 to 1300 pounds less than the Hyundai Ioniq 5.

The Prius Plug-In Hybrid is 4.5 inches shorter than the Ioniq 5 N, making the Prius Plug-In Hybrid easier to handle, maneuver and park in tight spaces.

The design of the Toyota Prius Plug-In Hybrid amounts to more than styling. The Prius Plug-In Hybrid offers aerodynamic coefficients of drag from .27 to .29 Cd (depending on bodystyle and options). That is lower than the Ioniq 5 (.282 to .313) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Prius Plug-In Hybrid get better fuel mileage.

The Prius Plug-In Hybrid’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Ioniq 5’s standard passenger windows don’t open or close automatically.

If the windows are left open on the Prius Plug-In Hybrid the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (This window function must be activated by your Toyota service department.) The driver of the Ioniq 5 can only close the windows from inside the vehicle, with the ignition on.

The Prius Plug-In Hybrid’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Ioniq 5’s standard manually variable intermittent wipers have to be constantly adjusted.

Consumer Reports rated the Prius Plug-In Hybrid’s headlight performance “Good,” a higher rating than the Ioniq 5’s headlights, which were rated “Fair.”

The Prius Plug-In Hybrid has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel is only available on the Ioniq 5 SEL/Limited/XRT/N.
