Abstract
A motor vehicle body structure has a vertically oriented front door latch pillar. The pillar is formed of a light metal alloy. The pillar has an upper end joined to a side roof rail and a lower end joined to a side sill. At a transition point between the upper and lower ends, the pillar defines a boundary between an upper structure portion and a lower structure portion. The upper structure portion extends between the upper end and the predetermined point. The lower structure portion extends between the predetermined point and the lower end. The upper and lower structure portions implement reinforcement and deformation permission measures, respectively.
