The Stinger has standard Active Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Headrests system moves the headrests forward to prevent neck and spine injuries. The Regal Sportback doesn’t offer a whiplash protection system.

The Stinger GT2 has a standard Surround 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 Stinger GT1/GT2’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 Stinger and the Regal Sportback have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height-adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, crash mitigating brakes and lane departure warning systems.

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, with its optional vehicle-to-vehicle front crash prevention system, with its optional vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Stinger 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 Stinger GT1/GT2’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Regal Sportback’s manually variable intermittent wipers have to be constantly adjusted.

Consumer Reports rated the Stinger’s headlight performance “Fair,” a higher rating than the Regal Sportback’s headlights, which were rated “Poor.”

While driving with high beams on, sensitive light sensors standard on the Stinger GT1/GT2 detect other vehicles which could be blinded and automatically switch to low beams. The Regal Sportback doesn’t offer automatic dimming high beams.

The Regal Sportback (except Base)’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The Stinger GT2’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

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

The Stinger has standard heated front seats. Heated front seats are only available on the Regal Sportback Essence/Avenir/GS. The Stinger GT2 also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Regal Sportback.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Kia Stinger has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Regal Sportback and isn’t available on the Regal Sportback Base/Preferred.
