Automotive design with economy, safety and aesthetics have been a great challenge to design engineers. Augmenting to these factors today environment impact is an upcoming research area. The safety of the passengers during vehicle crashes can be ensured to a certain limit by using good bumpers. At the same time these automotive parts should not be massive in terms of weight contributing to the increase in total the weight of the vehicle. In this work, a bumper used for low passenger vehicle, Ambassador car is modelled by using the software CATIA V5R18. Then this model is imported into FEM package of ABAQUS 6.10 impact as well as static analysis. Again modal analysis and analysis under dynamic loading done for the same model using ANSYS Workbench 11.0. The materials used for these analyses are Aluminum B390 alloy, Chromium coated mild steel and carbon composite. During static analysis, Carbon composite shows the lowest deformation and maximum von mises stress value. After the impact analysis, the composite shows the highest stress value, lowest deformation and the lowest strain value on compared with above materials. The analysis under the dynamic loading shows this carbon composite has the maximum stress value and it having the highest strength to weight ratio and producing low deformation. From all these analysis, it can concluded that carbon composite is the best material which can use as the bumper material among all the other materials used here.
