The rise of electric vehicles (EVs) has become a cornerstone of sustainable mobility in modern society. The foundation of this revolutionary change is mechanical design and simulation, which play a key role in optimising the performance and increasing the sustainability of EVs. As part of this effort, a simulation was conducted to investigate the potential effects of replacing an internal combustion engine-based powertrain with an electric one on the fundamental parameters of the vehicle. Within this framework, aspects such as estimated range and vehicle acceleration, among others, could be examined. The simulation helps to determine the ideal parameters of the powertrain during the design process before the prototype is implemented. This article examines the possibilities of electrifying a passenger vehicle with a conventional drive train using simulation. In the research, the transformation was carried out using two different methods, and then the two methods (Matlab Simulink Simscape and Matlab Simulink) were compared.
