Improvement of vehicle's drag coefficient in the wind tunnel

In order to optimize vehicles with regard to their speed characteristics and acceleration, fuel economy as well as handling, it is necessary to improve the vehicle’s drag coefficient (Cd). Drag is the force that impacts the vehicle in direction of the airflow. The drag coefficient is the main measurement of a vehicle’s aerodynamics. In research and development, manufacturers work on optimizing various performance characteristics in wind tunnel tests, including the drag coefficient.
