An analysis on the aerodynamic attributes of motor vehicles has been carried out. The main idea of the analysis was to determine the influence of various surface features on the drag force that is acting on a vehicle.

A scale model of a Mercedes-Benz SLS AMG was used as a base model to be modified. The computer aided design (CAD) model of the SLS was created in Creo 2.0 using a surface modelling technique. A standard model of the car was created and then modified to reduce the drag force acting of the car. Certain features were added to the model as well as changing some of the more turbulence reducing shapes on the model.

The CAD models were both analysed with computational fluid dynamics (CFD) software to determine the drag coefficient of the base car and the modified model. In conjunction with the software analysis a diecast model of the SLS and a 3D printed model of the modified car were used in wind tunnel testing. The aim of the wind tunnel testing was to see how the software analysis corresponds to physical results of the drag force on the models.
