  • Abstract:
  • This research investigates the impact of integrating rear wing spoilers with NACA 4-Series airfoils on the petrol consumption and fuel efficiency of a sedan car at 100 km/h. The study evaluates the effects of NACA 0012, 2412, 4412, and 6412 airfoils at angles of attack of 0°, 5°, and 10° on the downforce, drag, and lift coefficients of the vehicle. Computational fluid dynamics (CFD) simulations using ANSYS Fluent software were conducted to analyze the airflow around the sedan, specifically a Hyundai Verna, equipped with various rear wing configurations. The findings indicate that the rear wing with NACA 2412 airfoil at a 0° angle of attack significantly improves aerodynamic efficiency, resulting in a 7.8% reduction in power consumption and an 8.5% increase in fuel economy, thereby enhancing the Verna's fuel efficiency from 19.2 kmpl to 21 kmpl. This study underscores the potential of aerodynamic modifications to significantly enhance vehicle mileage.
