This study aims to integrate the aerodynamic characteristics of high performance sports cars into next generation energy management strategies. Two dimensional (2D) computational fluid dynamics (CFD) analyses were performed using a three-element rear wing featuring the S1223 airfoil geometry. Going beyond the conventional Drag Reduction System (DRS) concept, two novel operational modes were tested: an innovative "Aircraft Mode" featuring a 180-degree inverted flap to neutralize downforce and reduce rolling resistance, and an "Airbrake" mode designed to support instantaneous deceleration. Based on the results obtained from an ultra-fine mesh structure (103,675 elements), the drag and lift coefficients in the baseline high downforce mode were measured as c_d = 0.0883 and , c_l = -3.7916 respectively. The Aircraft Mode reduced the aerodynamic load on the rear axle, with the lift coefficient decreasing to c_l = -0.290, while substantially reducing the drag coefficient to c_d = 0.0239 . Conversely, the Airbrake mode increased the c_d value to 0.5683, generating an aerodynamic braking effect. The results suggest that multi-mode active aerodynamic configurations may support MGU-K-based energy management strategies by simultaneously managing aerodynamic drag and downforce across different driving conditions.
