To earn the Top Safety Pick+ award also requires high marks in automatic emergency braking and headlight testing. The IIHS gave the GLC the highest "Superior" rating for the collision avoidance system both on the standard model and the one with optional pedestrian recognition, since both systems brought the car to a stop, avoiding a crash, at speeds of 12 mph and 25 mph. The standard model did lose a point for not having an adequate driver warning system.
Among the three types of headlights available on the GLC crossover, two of them were good enough for the Top Safety Pick+ rating. Both of these headlight types are optional equipment and use LEDs. The basic optional headlight earned the second-highest rating of "Acceptable," while the more high-end headlight earned the "Good" rating. The GLC's standard halogen headlights earned the second-worst rating of "Marginal." So if you want a GLC with the best safety equipment possible, opt for the LED lights.
