Four more cars have received the “Top Safety Pick+” award from the Insurance Institute for Highway Safety (IIHS).

After releasing a rather worrying study about underperforming headlights, IIHS is now handing out a “Top Safety Pick+” award to the latest Toyota Prius, Nissan Sentra, Infiniti QX60, and the Kia Optima. In order to be eligible for this award, cars must receive good ratings in the small overlap front, moderate overlap front, side, roof strength, and head restraint tests. In addition, cars also must benefit from a front crash prevention system that must receive from IIHS an advanced or superior rating.

The all-new Prius aced the small overlap front test and the model was also praised for its optional front crash prevention system which grabbed a superior rating. As a reminder, the old Prius scored good ratings in four of the five tests and was rated acceptable in the small overlap protection.

Moving on, the 2016 Nissan Sentra (which we reviewed about a month ago) and the 2016 Infiniti QX60 both earned good ratings in all five crashworthiness tests, just like the 2015MY. Both recently received an optional front crash prevention system and IIHS also credited the two for the forward collision warning components in the crash prevention system which meets the National Highway Traffic Safety Administration (NHTSA) criteria.

Last but not least, the 2016 Kia Optima (which we also reviewed) earned good crashworthiness ratings across the board, while its optional front crash prevention system scored a superior rating. The 2015 Optima had a good rating in all tests, except for the small overlap front where it only managed to get an acceptable rating. It doesn’t come as a surprise the new Optima has obtained the “Top Safety Pick+” award, since sister model Hyundai Sonata also has it.
