Abstract: The optimization of aerodynamics plays a pivotal role in enhancing fuel efficiency in passenger vehicles. With rising fuel costs and increasing environmental concerns, improving vehicle design for minimal drag becomes crucial in reducing fuel consumption and carbon emissions. This study explores the impact of various aerodynamic modifications on fuel efficiency, focusing on design elements such as vehicle shape, airflow management, and the integration of advanced aerodynamic components. Through the use of computational fluid dynamics (CFD) simulations and wind tunnel testing, this research quantifies the effectiveness of different aerodynamic strategies. The findings suggest that drag reduction strategies, including the refinement of the vehicle's body shape and the introduction of aerodynamic components such as spoilers and diffusers, lead to significant improvements in fuel efficiency. The study further compares the impact of traditional aerodynamic techniques with the adoption of emerging technologies, such as active aerodynamic systems and lightweight materials, in enhancing overall vehicle performance. This paper concludes by identifying potential areas for future research, including the integration of new materials, the use of AI-based optimization models, and the exploration of aerodynamics in larger vehicle classes. These findings contribute to the broader automotive design efforts aimed at reducing fuel consumption and promoting sustainability.
