We report an experimental investigation about the aerodynamics of a simplified road vehicle, the so-called square-back Ahmed body, under rainfall conditions. A particular emphasis is put on the evolution of the body base pressure distribution with respect to the operating conditions. It is found that rainfall significantly damps both mean base pressure drag and wake dynamics in comparison to dry conditions.
