Recently, the high speed limit and high performance of cars have been advanced. Then it is necessary to adapt them to environmental problems and improve passengers' comfort. Therefore, the aerodynamic characteristics have more importance. Car companies have devised the shapes of bodies and parts, and reduced the drag and lift. The purpose of the present research is the investigation of the effects of the spats and strakes on the aerodynamic characteristics. A wind tunnel with a moving belt was used to measure the drag and lift. As a result, the drag is decreased when the spats are attached on the wheelhouses, but is not very much when the strakes are attached on the underfloor.
