Experimental investigations were carried out aiming at the reduction of the total aerodynamic drag of a generic car model by means of active flow control. Considering the complexity of the near wake of the car model the actuation system consists of steady blowing to influence streamwise vortices, while periodic perturbations were used to control shear layer vortices. This study describes a successful approach for active drag reduction of a generic car model using these different types of actuation simultaneously. A slope-seeking controller is used to find the optimal forcing parameters in order to reduce the overall drag.
