The stricter guidelines focus on how well passengers in the front seat are protected in frontal collisions that simulate hitting a tree or pole, which the IIHS calls the small-overlap test. And this year the IIHS is making the criteria more hard for automakers to earn a top grade.
The number was actually down from past year and the new crash tests were not the only reason why.
"Doesn't mean that vehicles have gotten less safe, it really just reflects that we've raised the bar", IIHS President Adrian Lund told CBS.
This year, of the 15 vehicles to earn the Top Safety Pick+ (TSP+), the highest safety rating available, four of them were Subaru models. This institute conducts crash tests and evaluates automobile safety standards. It began measuring both how well low and high beams illuminated the road and the amount of glare they produce for oncoming vehicles as part of its ratings in 2016. Previously, only the vehicle's performance in the driver's side was tested.
An additional 47 vehicles earned a Top Safety Pick rating.
Vehicles the IIHS studied included small cars, midsize cars, large luxury cars, midsize SUVs and midsize luxury SUVs. It has no commercial relationship with any advertiser or sponsor on this site.
