The mudguard in an automobile is used to prevent sand, mud, rocks, liquid and other materials being throne into air by the rotation motion of the tire. In electric vehicles such as Ecoist vehicles will try to reduce the weight of the body part and increase the aerodynamic efficiency by good designs. The purpose of this project is to design a mudguard for this vehicle with more aerodynamic efficiency in a light weight material. In this thesis work a mudguard has been designed in a light weight material and also designed a supporting bracket for the easy installation of the mudguard as well as the tyre to the vehicle.
