Abstract
A vehicle includes a rocker support that extends in a vehicle longitudinal direction. A side roof rail structure extends in a vehicle longitudinal direction along a vehicle roof assembly. A front pillar assembly is coupled to and extends upward from the rocker support to the side roof rail structure. The front pillar assembly includes a first panel that extends along a height of the front pillar assembly at a front side of the front pillar assembly. A second panel extends along the height of the front pillar assembly that is connected to the first panel at least partially defining an enclosed cavity that extends along the height of the front pillar assembly. The first panel is formed of a material having a lower minimum tensile strength than a material forming the second panel thereby forming a zone of reduced minimum tensile strength along the front side of the front pillar assembly.
