This review paper reveals about the lightweight materials impacting the economy, efficiency and the performance of the automobile. Carbon fiber and aluminum has a tendency to be a lighter material when contrasted with different metals like steel and has a more extensive scope of utilization in the automotive field. High quality steel materials can be recyclable which makes the material to be financially productive. Carbon fiber has high obstruction against destructiveness when contrasted and the ongoing materials utilized in the automotive industry. High quality steel materials are cost effective. The consistently developing enthusiasm for carbon fiber in vehicles is associated with the one of a kind arrangement of their properties. The utilization of carbon fiber in the structure of vehicles is impeded by two components, to be specific, the expense of fiber materials, or, in other words than that of different steels utilized in the car business, and the troubles in assembling auto bodies under the states of present day huge scale creation. Nonetheless, the proficiency of a structure ought not be assessed just regarding the expense of the material without considering different implies that give this productivity, i.e., hierarchical, operational, assembling, and plan ones.
