About This Item

This terminology document is intended to provide a common nomenclature for use in publishing road vehicle aerodynamics data and reports. This revision of the document includes the addition of an appendix to provide a suggested naming convention for typical components used on passenger cars and light trucks for aerodynamic purposes. Multiple naming conventions are in use, and this is meant to provide a recommended terminology for related literature and for use in the community of vehicle aerodynamicists. The contributions of the United States Council for Automotive Research Aerodynamics Working Group and the SAE Truck and Bus Aerodynamics and Fuel Economy Committee are gratefully acknowledged. The reader’s attention is also drawn to the previous revision to the axis system used so that x-positive is rearward and z-positive is upward. This change did not affect the positive sense of aerodynamic forces and moments.
