BODY STRUCTURE


  1. FUNCTION


    1. Impact Absorbing Structure for Front Collision


      1. To help minimize the deformation of the cabin in case of a front collision, the following parts effectively dissipate the energy of the impact applied to the front of the vehicle: the front bumper reinforcement, front side member sub-assemblies, under-floor members, front panel member, floor tunnel side members, rockers, front body pillars, center body pillar reinforcement sub-assemblies, door inner reinforcements and front door side impact protect beam.

      2. The load box reduces the time needed to transfer the impact energy to the underbody at the moment of collision.
