The objective of this work is an attempt to understand the potential for aerodynamic improvements by the application of different underfloor panels that might be masked by traditional fixed-ground wind tunnel testing. The coastdown method is chosen to determine drag coefficients on the road which could then be compared with wind tunnel data. Of prime importance were the simplicity and practicability of the developed analysis method, with particular emphasis on industrial applicability. As a result of the investigations, the resolution of the new method and an astonishing conformity of the identification of small changes in the underfloor configuration of the test vehicle with wind tunnel tests are demonstrated.
