2018 will be much heavier, bigger, with poorer visibility thanks to huge crash and rollover resistant A, B and C pillars. It will also have passed the pedestrian impact tests and have enormously better brakes and handling. So even though heavier it'll stop a lot quicker, and do less serious damage to a pedestrian at town speeds. That's quite apart from any safety features like air bags or ABS.
