The contribution of aerodynamics for the durable and safety development in automotive is presented and argued from research tasks intended to control the flows to reduce consumption and to improve dynamic stability. The results reveal the complexity of the physical phenomena and the problems to solve to be able to act on the appearance mechanisms, development, interaction and on the stability of the unsteady separated three-dimensional structures. This complexity confirms the need for developing co-operations in order to improve comprehension of the physical phenomena and to seek solutions which make it possible to control separated flows associated or not with transient configurations.
