A critical requirement for product design and development is meeting vehicle dynamic performance. Customers changing needs puts tremendous pressure on automotive businesses to launch new vehicles within short durations of time. This makes it mandatory to have a wide-ranging virtual simulation and vigorous validation process to provide best in class ride and handling performance of vehicles. Physical testing of prototypes is the most time-consuming activity, so there is a need of front loading to substitute these requirements at the initial stage of the development cycle. This paper summarizes the overall process for front loading vehicle dynamics requirements during basic architecture definition using virtual simulation. Basic dimensions, CG, weight distribution and steer angle of the new vehicle are derived using concept calculations based on benchmark vehicles. Vehicle dynamics trials are then done for the benchmark vehicles.
