Abstract

Today’s most hot selling cars on the market are sedan. Thus, people have more expectations at the semi
drange budget cars. These expectations could be achieved by increasing the car performance such as
fuel economy, aesthetics and speed and reducing the drag force which is applied on it. Fuel economy
and speed could be easily achieved by decreasing the drag coefficient and drag forces. Drag plays one
of the major roles in fuel economy and speed of the vehicle. Thus, altering the car design would be
helpful in achieving such things. This project deals with the design and analysis of drag reduction of
an automobile. The drag force pulls the automobile from back to reduce the speed and about 50-60%
of total fuel energy is lost to overcome this drag force. So, for reducing this aerodynamic drag, we have
to optimize its shapes to ensure streamlining. We’ve chosen SUZUKI KIZASH. The model of the car is
developed in Autodesk Fusion 360 and analyzed in ANSYS Fluent by Computational Fluid Dynamics
(CFD Analysis). Modifications on vehicle body would be increases of drag. Based on Cl and Cd values,
optimal model will select.
