Simulation analysis is the main part of CAE for car vehicle design/development and has been mainly utilized to decrease the number of cycles of detail design, prototype building, and testing. However, recently it is also used for the upper process of design and development such as planning for vehicle performance and now this situation has stronger effect on vehicle development. So, excellent accuracy of analysis is required, but as the simulation technique and hardware such as super-computer and workstation become satisfactory, it becomes realized drastically. And to utilize these simulation technique efficiently in design process, excellent analysis systems are required. So, in this paper, the conditions and the examples of analysis systems will be described such as analysis of vehicle and engine structure, crash analysis, vibration-sound analysis, aerodynamics quality analysis which use those analysis systems. The problems in near future are the construction of analysis expert systems, the extension of simulation analysis to manufacture and material development and decrease of time for making model for simulation analysis.
