Aerodynamic development and testing have become fundamental to successful motorsport and road vehicle programs. The aerodynamic development of the vehicle is fully integrated within the complete design cycle. A mix of development techniques are used throughout the process, where the exact selection of the development tool depends on many factors ranging from performance to accessibility and economics. For example, the wind tunnel provides efficient and fast results of the full vehicle design concept. Computational fluid dynamics (CFD) provides insightful iterations and optimizations of vehicle sub-systems, and provides visual cues that resonate well with production car stylists. However, recent advances bring more capabilities to each of the tools, and provide aerodynamicists with enhanced options to optimize aerodynamic performance parameters. For example, advancements in robotic particle image velocimetry (PIV) and pressure probe measurements provide detailed flow field visualizations. Advancements in computational power and algorithms allow for more advanced full vehicle analysis.
