This study delves into a comparative analysis of electric vehicles (EVs) and diesel vehicles (DVs) across emissions, design, technology, and fuel consumption. One of the aims is to reveal the relationship between changes in form-based mass of the designed part, material selection influenced by production technologies, and the resulting production emissions and mass-based fuel consumption. The research aims to elucidate the environmental impact of EVs and DVs, particularly focusing on emissions stemming from raw materials of the production. Methodologically, the study employs theoretical analysis alongside practical assessments using Autodesk Fusion 360 and CCaLC2 software for mass determination and emissions calculation, respectively. Through an examination of key parameters such as vehicle design, material usage, and powertrain systems, the study sheds light on the nuances of emissions generated by each vehicle type's parts. The research contextualizes the growing importance of sustainable transportation solutions in the face of escalating environmental concerns, emphasizing the need for rigorous evaluation of alternative fuel vehicles. By comprehensively analyzing data on emissions, design, and fuel consumption, the study provides insights into the complexities of sustainability in the automotive industry. The findings underscore the critical role of industrial design in emissions reduction and offer recommendations for stakeholders to prioritize sustainability in vehicle production and consumption practices. Also, mentioning important notes for green consumers who are buying products according to environmental effects. The study contributes to advancing understanding in the field of sustainable transportation and underscores the importance of methodological rigor in evaluating environmental impacts.
