Abstract: A vehicle front body structure containing an upper longitudinal beam and a upper fender rail for supporting a fender of the vehicle, said upper fender rail extending in a longitudinal direction substantially parallel to the upper longitudinal beam and having a front end and a rear end spaced apart along the longitudinal direction.
The resistance to plastic deformation of the upper fender rail increases from the front end of the upper fender rail to the rear end of the upper fender rail. The yield strength of the material of the rear section is greater than the yield strength of the material of the front section and/or the rear section has a greater wall thickness than the wall thickness of the front section.-
