<![CDATA[Given the energy challenges facing the world, particularly regarding fossil fuels, therefore, recent years, the demand for electric vehicles has increased. Electric vehicles are one of the innovations that have become environmentally friendly, as it decreases fuel consumption and reduce pollution. As LEVs play an increasingly important role in sustainable urban transport, optimizing their energy efficiency is essential. This study investigates the impact of vehicle weight variation on energy consumption in Light Electric Vehicles form change Weight 800Kg to 1400Kg (LEVs) across one of the drive cycles. Through simulation and modelling, we evaluate the impact of incremental changes in vehicle mass on energy demand during standard driving scenarios, including urban, suburban, and highway profiles. The model research was developed in MATLAB/Simulink. The analysis highlights that vehicle weight significantly affects energy consumption, particularly in stop-and-go urban environments where acceleration demands are higher. Results indicate that reducing LEV weight leads to measurable improvements in energy efficiency, thereby extending range and reducing battery strain. These findings support light-weighting strategies as a practical and impactful method for enhancing LEV performance and sustainability in real-world conditions, and change the energy consumption from 0.011 kWh to 0.017 kWh. These values highlight how increasing vehicle weight leads to higher energy consumption, even under the same driving cycle 500 sec.]]>
