Changing criteria for headlights is holding back many cars from getting top marks from the Insurance Institute for Highway Safety.
IIHS, which evaluates passenger vehicles for its Top Safety Pick and Top Safety Pick+ awards, gave 23 vehicles its Top Safety Pick+ award, down seven from the 2019 model year. IIHS President David Harkey told Automotive News that the decrease came from more stringent criteria for headlights.
Headlights, produced with polycarbonate and other engineering plastics, must have "good" or "acceptable" ratings from IIHS to be considered for safety designations. They must also offer "advanced" or "superior" front-crash prevention systems.
Only one Detroit 3 vehicle made the list: the Cadillac XT6, for models built after October 2019. The California-built Tesla Model 3 also qualified. The designation plays a part when consumers shop for vehicles, according to dealers.
