The 2014 Mercedes-Benz E-Class, which the Insurance Institute for Highway Safety classifies as a "large luxury car," has received the institute's highest safety honor, Top Safety Pick Plus. Helping to put it over the top, the E-Class earned a score of good in the small-overlap front crash test and offers standard front crash prevention technology. The vehicle also scored good in the other four testing areas: moderate overlap front, side, roof strength and head restraint.
IIHS added the small overlap evaluation in 2012 to replicate what happens when the front corner of a vehicle strikes another vehicle, tree or utility pole. To earn Plus status, a vehicle must receive a good or acceptable rating in this test, at least good on the other four crashworthiness evaluations, and basic, advanced or superior for front crash protection. The E-Class' standard Collision Prevention Assist scored a rating of basic for front crash protection, but when equipped with the optional Pre-Safe Brake system, that score is bumped up to superior.
