An energy absorbing and distributing side impact system for use with a vehicle is provided, the system utilizing a collapsible side sill assembly along with multiple vehicle cross-members to achieve the desired level of vehicle side impact resistance, the combination of these elements absorbing and distributing the impact load throughout the vehicle structure. The collapsible side sill assembly includes a side sill insert, the insert divided into a collapsible portion designed to absorb impact energy and a reacting portion designed to distribute the impact energy to the vehicle cross-members.
