As a result of the massive outgrowth in the computer aided engineering field, there exist a number of tools and techniques for determining the characteristic response for the body-in-white dynamics. Furthermore, there are as many analytical techniques for investigating various ways to enhance vehicle dynamic response based on analytical results from a body-in-white. The paper describes a tri-stage analytical approach aims at achieving a body-in-white model with dynamic characteristics that are optimized for better vehicle performance. The Tri-stage approach is based on the finite element method with varied degree of utilization at each stage. The first stage in the approach involves the use of the classical finite element technique to investigate possible structural modifications. This approach while proven accurate, has it's own limitations and disadvantages.
