Hyundai developing safety system calibrated for 'secondary impacts'

There is an inherent flaw with how traditional airbags are used and deployed: They can only reply to one impact. The Hyundai Motor Group wants to address this with a new "multi-collision airbag system" that focuses on impacts that occur after the first point of contact. Hyundai defines multi-collision accidents as "those in which the primary impact is followed by collisions with secondary objects, such as trees, electrical posts or other vehicles." In a press release, Hyundai noted that about 30 percent of roughly 56,000 accidents between 2000 and 2012 in North America involved these types of multi-collisions, according to the National Highway Traffic Safety Administration (NHTSA)'s National Automotive Sampling System Crashworthiness Data System division. The airbag systems in today's cars don't always go off when the first accident occurs, and when a car goes through a secondary impact, the airbags may no longer provide the best safety. Hyundai's new system can read the positions of the car's occupants and react in a more beneficial way. It can quickly recalibrate after the first impact based on readings from the vehicle and the people inside, which allows the second part of the crash to trigger the airbags. As of now the system is still in development, but Hyundai Motor Group is planning to use it in both Kia and Hyundai vehicles in the future. Which models and which markets it will apply to first are yet to be determined. Related Video:

2018 Kia Rio is the only subcompact car to earn IIHS highest safety rating

If you're looking for a new subcompact car, and safety is your priority, there is one clear choice now: the 2018 Kia Rio. The littlest Kia has been awarded the highest safety rating from the IIHS, the Top Safety Pick +, and it is the only car in the subcompact segment to earn the score. In addition, only two other models earn the second highest rating Top Safety Pick, sans plus, the Hyundai Accent and the Mini Cooper. The Rio's rating is an increase from the sans plus version because Kia updated and improved the headlights for the 2018 model. There is a caveat, though. Only the optional LED projector headlights, available as an option on the midlevel S trim, are rated "Good," the highest IIHS rating. The standard halogen headlights are still rated "Poor." The Rio's forward collision prevention system that earned full marks is also only available as standard equipment on the top-level EX trim. Still, even lower-trim Rios with the less capable headlights and no automatic emergency braking boast strong crash test scores. Every test except for the passenger-side small overlap test resulted in Good ratings. The passenger-side small overlap test garnered the second-highest rating of "Acceptable." And on top of that, it's a car that has impressed us every time we've driven it. Related Video:
