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 are reminded to check the back seat if they opened the rear door before starting out. The Regal Sportback doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The Sonata Limited has standard Reverse Collision-Avoidance Assist that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Regal Sportback doesn’t offer backup collision prevention brakes.

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

The Sonata’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 Regal Sportback doesn’t offer a driver alert monitor.

Both the Sonata and the Regal Sportback 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, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available blind spot warning systems and rear cross-path warning.

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 the rating of “Top Pick” for 2020, a rating granted to only 30 vehicles tested by the IIHS. The Regal Sportback has not been fully tested, yet.

The Sonata’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 Regal Sportback’s manually variable intermittent wipers have to be constantly adjusted.

While driving with high beams on, sensitive light sensors standard on the Sonata detect other vehicles which could be blinded and automatically switch to low beams. The Regal Sportback doesn’t offer automatic dimming high beams.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Sonata SEL/SEL Plus/Limited has standard extendable sun visors. The Regal Sportback doesn’t offer extendable visors.

The Sonata Limited’s Remote Smart Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Smart Parking Assist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Regal Sportback doesn’t offer an automated parking system.
