There are numerous parameters that affect the handling characteristics of ground vehicles. Among those, lateral and torsional body stiffness plays a major role. Increasing the body stiffness not only improves the handling characteristics, [1] but also other properties like crashworthiness, [6], Noise Vibration & Harshness [NVH], and durability, [2], [3]. But a body with high stiffness, demands a higher weight and cost because of the increased panel thickness required and reinforcement members. Car manufactures try to reduce the vehicle weight to improve the fuel efficiency, because this is one of the primary criteria based on which customers purchase vehicles. In the process of achieving a light weight body, the body stiffness may suffer. As a result of many earlier studies, it is known that increase in stiffness of the vehicle body improves the handling of the vehicle, [2].
