A motor vehicle refers to any self-propelled vehicle built for transporting passengers or goods on roadways. Typically powered by internal combustion engines or electric motors, motor vehicles encompass cars, trucks, motorcycles, and buses. They are essential to modern life, providing convenient and efficient transportation and supporting both personal mobility and economic activities such as freight transport. Technological advancements have resulted in hybrid and electric vehicles, which seek to lower emissions and reduce reliance on fossil fuels. Motor vehicles play a crucial role in research across various fields, significantly impacting transportation, environmental studies, and urban planning. Their importance lies in their contribution to mobility and economic development. Research on motor vehicles helps to study traffic patterns, leading to the creation of traffic management systems that improve safety and reduce congestion. Environmental studies, on the other hand, focus on the impact of motor vehicles, particularly concerning greenhouse gas emissions and air quality, to inform policies that encourage cleaner alternatives like electric and hybrid vehicles, addressing issues like climate change and pollution. " While various normalization methods can be applied in WSM, the results can vary depending on the chosen method. In contrast, the WPM eliminates the need for normalization by using multiplication rather than addition to combine the data. Toyota Corolla, Honda Civic, Ford Focus, and Hyundai Elantra, Tesla Model 3, Mazda 3, Volkswagen Golf, Chevrolet Cruze. Fuel Efficiency (km/L), Safety Rating, Comfort, Resale Value (%), Price ($) CO2 Emission (g/km), Maintenance Cost ($/Year). The findings indicate that Volkswagen achieved the highest rank, whereas Hyundai was placed at the lowest.
