- Discussed in this paper are the aerodynamic features of the Western Michigan University Gamma passenger vehicle. The vehicle was designed and constructed for the 1980 Sea-to-Sea Econorallye II. Incorporated in the design were aerodynamic modifications, with special emphasis on front and rear body shapes.The main objective of the aerodynamic modifications was to reduce the drag coefficient of the vehicle. Methods of analysis were scale model wind tunnel testing and coastdown testing.A series of wind tunnel tests were performed with a 1/15th scale detailed model of the prototype. The forces which contribute to the resistance of the motion are discussed. Wind tunnel philosophy, techniques, and assumptions are also discussed.Coastdown tests were performed to determine the drag as measured on the road. The drag coefficient was determined by statistical analysis of the test data.
