Abstract

In recent times, electric vehicle adoption has become more prominent as engineering diverts towards sustainability. A considerable share of the globe's energy consumption is reviewed to be from the transportation industry, which directly translate, to a significant quantity of emissions into the atmosphere from burning the fossil fuels. Therefore, global energy consumption and greenhouse gas emissions have the loudest voice over automobile design considerations for sustainability. This have also led to the deployment of more stringent environmental regulations to most automotive manufacturers. Automobile industry is researching and creating innovative technologies to cut down on fuel usage and increase vehicle efficiency whilst reducing the carbon emissions simultaneously. The main objective of the current research is to identify and analyze the aerodynamic drag resistance with the change in the vehicle dynamics. Reduction of the drag coefficient will significantly reduce power consumption and increase vehicle efficiency. Electric vehicles currently being designed need to achieve greater efficiency, superior stability and safety even at higher vehicle speeds with considerably long driving range. This study focusses on the analysis of energy consumption of a car model focussing more on the significance of aerodynamic drag.
