In automotive development, the main characteristics of a new car model are determined in the initial phases of product generation. Since the conceptual definition has to consider various, partially conflicting boundary conditions and requirements, the resulting vehicle concept always represents an outcome of intensive optimization processes. This multidisciplinary optimization requires a high flexibility from the tools, methods and processes applied. In the present approach, an integration of computer - aided design (CAD) and computer - aided engineering (CAE) disciplines form an easy - to - handle tool to support and maintain the entire conceptual full - vehicle process. This starts with initial ideas, sketches and specifications, continues with 3D - CAD representation of boundary conditions, forming preliminary and eventually final vehicle concept geometries, and finally provides functional layout procedures for weight estimation, propulsion layout, driving dynamics behaviour and aerodynamic characteristics.
