A vehicle frame (10) including longitudinally extending side rails (12). Each of the side rails (12) has a hollow beam structure and includes a series of sets of corner divots (24) along the corners (22). Each corner divot (26) extends along one side (20) a distance (L) and along an adjacent side (20) a shorter distance (S). The long and short portions of each corner divot 26 are oriented opposite to the corner divots (26) on either side of it along the same corner (22), and the long portion (L) is located on a side where it and the adjacent corner divot both have their respective long portion (L) on this side (20). This forms an asymmetrical pattern of divots on each of the frame rails (12), providing improved crush characteristics along the frame rails (12).
