The Turbulence Generation System designed and built in Pininfarina in the years 1999-2002, has been in operation since the beginning of 2003. The purpose of this device is to reproduce in the wind tunnel a flow condition more similar to that found by the cars on the road, in terms of velocity profile and turbulence intensity/length scale.The paper reports an updated description of its mechanical and aerodynamic characteristics.Then it reports examples of results measured on some cars, in the condition of turbulent flow, regarding: The differences between these results and those measured in standard low-turbulence conditions are presented.In addition a description of some techniques that are used for these time-dependent measurements is reported.
