The objective of this project is to model the vehicle body design and do analysis of a practical, fuel efficiency city concept car and from the result obtained, studies will be carried on to increase the fuel efficiency of the base model which is PeroduaMyvi by the means of changing the body design of the carfocusing to reduce the drag coefficient and the coefficient of lift of the vehicle. The PeroduaMyvi is one of the leading local cars in its class due to its fuel efficient and lightweight. However, there are always rooms for improvement forMyvi body design so that the fuel efficiency can be increased. The scope of study of this project will be as follow: · Study about ways to reduce drag coefficient and rolling resistanceby changing the design of the body. This includes the factors like the material used for the body and aerodynamic design. Study and construct the model and simulate it using Catia and ANSYS fluent software to measure drag coefficient and coefficient of lift under different driving condition. Analyze the obtained results and propose some potential improvements that can be implemented to obtained fuel efficiency car. The methodology for this project basically has more emphasis on using the CATIA and Fluent software. Some equation will be used to calculate the relationship between aerodynamic design and fuel consumption to enable the objective of this project to obtain high fuel efficiency based on the vehicle body design.
