Abstract	Vehicle response and stability plays important role in ensuring superior handling characteristics, especially on diverse and challenging Indian road conditions. This paper focuses on parametric benchmarking of vehicle response and stability, giving a systematic approach to analyze these parameters as well as to set performance target during initial stages of vehicle development. In this paper, key parameter like front and rear roll steer coefficient, front and rear compliance steer, tire cornering stiffness, vehicle characteristic speed and yaw rate gain are analyzed using data measured from vehicle dynamics test bench. By analyzing the relation between these parameters, this paper aims to provide insights that will be helpful in decision making for vehicle development. The findings from this study will assist readers how to use data from vehicle dynamics test bench for benchmarking as well as to analyze the vehicle handling performance.
Keywords	Vehicle dynamics, response and stability, yaw rate gain, slip angle gradient, understeer gradient, compliance steer, roll steer, tire cornering stiffness, vehicle characteristics speed, benchmarking, target setting, handling performance, twist beam, multi-link suspension
