Abstract The primary objective of this study is to experimentally measure the aerodynamic properties of various commonly used vehicle add-ons (police siren, advertising sign, taxi sign and roof rack) and roof load (e.g., ladder and barrel) under a range of vehicle operating speeds and yaw angles using RMIT Industrial Wind Tunnel. The study was conducted using a reduced scale (25%) detailed model of a production car manufactured in Australia. The results show that the vehicle add-ons have notable impact on aerodynamic drag as the can generate 5 to 40% more aerodynamic drag depending on yaw angles. The taxi sign has minimum impact and the advertising sign has highest impact on aerodynamic drag. Also roof load such as ladder and barrel can significantly increase the drag. Furthermore, the aerodynamic drag was related to a range of commonly used fuels e.g., petrol, diesel, compressed natural gas (CNG), liquefying petroleum gas (LPG) consumption and their relative greenhouse gas emiisions.
