a Modern hatch has the active safety electronics, but the older euro possibly has the passive crumple zone engineering. one would think a design to surpass a standard would be better than one which was designed to merely achieve a minimum standard.
Really though, accidents are unpredictable and can go seriously fatal in millimeters. I have seen a e34 5er flip in crosswinds (at possible extralegal speeds) and the chap who walked away was very lucky to have lived, as the initial impact hit soft earth, missing the hard concrete highway surface by a mere 500mm.
