A new designed vehicle has to have a character which is describing itself. Factors forming the character of the car are its properties. Necessary modification has to be applied in the early design phases to achieve desired properties. But any re-design causes a feedback study in the design phase. The earlier these modifications are applied the shorten is the design phase and the lower are the costs invested for design. One of the most important method to reduce design and development time is to being able to analyze and optimize vehicle properties and being able to recognize the effects of the change of design parameters on properties even in early design phases. The optimization of vehicle properties such as comfort, economic, safety and performance form the most significant stage of the vehicle design. Nowadays, vehicles are expected to provide a lot of properties at the same time. But unfortunately, improving some properties is mostly resulted that other properties are affected in a negative way by this change. Parameters which form the properties of the vehicle can be changed in definite limits to keep some other properties in desired values. This kind of studies on this subject is forming an optimization problem. The common result which will be reached at the end of these researches is having a lot of alternative solutions due to the complex effects of vehicle properties with each other. Furthermore, if we examine vehicle properties, it is clear that there will be various solutions for each special goal. In other words it is clear that there can not be a unique reasonable solution for a vehicle design. Priority properties and rank of important of characteristics are being evaluated. These evaluations will be fruitful for us to determine which properties are much more essential in this stage. It is clear that, the more property the system has, the better solutions it will have. …
