The weight of a aluminum intensive vehicle(AIV) can be generally reduced to about 30 percents than conventional steel vehicle without the loss of crash energy absorbing capability. In this paper, energy absorbing characteristics of aluminum extrusions are investigated from the axial and bending collapse test results. Using the crush test and analysis results, the design concepts for the effective energy absorber of aluminum extrusions are suggested. Full car crush/crash simulation of AIV are performed based on the FMVSS 208 regulations and the improved safety design concepts of AIV are evaluated in comparison to the conventional steel monocoque vehicle
