Hi together, stumble just over the remark “… the roof of the XC90 is composed of Boron steel, which Volvo notes is four times stronger than conventional steel.” I find it interesting that the roof of the XC90 4x is more stable than that of an XC70. However, since the entire XC90 roof construction is larger and in case of an overlay it must carry more own weight of the XC90 body, I guess the impact on the passenger cell will remain similar (hopefully be i both XCs always sufficient).Tschau Torsten – the XC fan (and talking foreign today)
