The aerodynamic effect plays a major role in the fuel efficiency and stability of the vehicle. The contact patch loads between the tire and road also play a vital role in the stability and fuel efficiency and are directly related to the vehicle load. In this research, lift force generated because of an additional wing attached to the car is studied. While the vehicle moves around 40–130 kmph. Upward vertical lift force produced from aerodynamics reduces the weight of the car virtually. The wing or airfoil is attached to use the gap between the car’s top surfaces to the lower surface of the wing to cause a Venturi-like effect. Lightweight car will be able to make more efficient use of its tires than a heavier car. Computational fluid dynamics (CFD) analyses are done with ANSYS Fluent. The validation of airflow characteristics, lift and drag forces from simulations, is done with data from wind tunnel testing. The study was carried out by varying parameters such as height between the upper surface of the car and the lower surface of the wing, and wingspan. The result obtained shows that the weight of the car can be reduced by 11% virtually with the wing forces, and the payload could increase by 11% or improve the fuel efficiency by 10–15%.
