Though I didn't really expect Mercedes to score any less than five stars when it comes to safety. Their standards are pretty high imo and buyers expect exceptional safety ratings. It even managed to get 80% mark for pedestrian protection, which seems amazing considering how much damage a pickup can do to a person.
