- The transition from traditional gasoline-powered automobiles to electric vehicles (EVs) has taken time, two major challenges of engine- powered vehicles are greenhouse gas emissions and fuel economy. Electric cars require less maintenance. A lot of money can be saved while also helping the environment. In today's world, working with lightweight materials have emerged as a key area for improvement in the automotive industry. The most efficient method for increasing power output is to reduce the weight of vehicle components. Composite materials have benefited greatly from research and development because they are stronger, more recyclable, and easier to integrate into vehicles. The primary goal of this research is to design the body and chassis frame of a two-seater electric car. A CFD analysis was performed to determine the drag coefficient of the body along with structural analysis to obtain the frontal impact and torsional rigidity of the chassis to develop an effective electric car design. The design was carried out with the help of CATIA V5 software, while the analysis was performed using ANSYS 19.2. A comparative analysis of the chassis was undertaken by incorporating three different materials namely, traditional steel i.e., Stainless Steel 304L, Aluminium Alloy 7075-T6, T300 Carbon Fibre composite. The energy efficiency of the car for the three materials are also computed.
