In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Sonata Hybrid are reminded to check the back seat if they opened the rear door before starting out. The Prius doesn’t offer a back seat reminder.

The Sonata Hybrid Limited has a standard Around View Monitor to allow the driver to see objects all around the vehicle on a screen. The Prius 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.

Both the Sonata Hybrid and the Prius 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 driver alert monitors.

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 Sonata Hybrid the rating of “Top Pick” for 2020, a rating granted to only 30 vehicles tested by the IIHS. The Prius last would have qualified as a “Top Pick” in 2019.

When two different drivers share the Sonata Hybrid Limited, the memory system makes it convenient for both. Each setting activates different, customized memories for the driver’s seat position, outside mirror angle, climate settings and radio stations. The Prius doesn’t offer a memory system.

The Sonata Hybrid’s power parking brake sets with one touch and releases with one touch or automatically. The Prius’ parking brake has to released manually.

The power windows standard on both the Sonata Hybrid and the Prius have locks to prevent small children from operating them. When the lock on the Sonata Hybrid is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Prius prevents the driver from operating the other windows just as it does the other passengers.

The Sonata Hybrid’s power window and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Prius’ cruise control switches are unlit, making them difficult to find at night and operate safely.

The Sonata Hybrid’s speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The Prius L Eco/LE’s standard manually variable intermittent wipers have to be constantly adjusted.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The Sonata Hybrid’s available headlights were rated “Good” by the IIHS, while the Prius’ headlights are rated “Acceptable.”

The Sonata Hybrid has a standard automatic headlight on/off feature. When the ignition is on, the headlights automatically turn on at dusk and off after dawn. The Prius has an automatic headlight on/off feature standard only on the XLE/Limited.

When the Sonata Hybrid Limited is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Prius’ mirrors don’t automatically adjust for backing.

Standard air-conditioned seats in the Sonata Hybrid Limited keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Prius doesn’t offer air-conditioned seats.

The Sonata Hybrid’s standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. The Prius doesn’t offer dual zone air conditioning.

Both the Sonata Hybrid and the Prius offer rear vents. For greater rear passenger comfort, the Sonata Hybrid SEL/Limited has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter.
