The cost of fuel and the desire for fuel efficiency continue to drive automobile manufacturers to invest in and to prioritize vehicle designs and performance. There has long been a fundamental understanding that aerodynamic efficiency (drag) has an effect on this phenomenon. The focus of this paper is to demonstrate how emergent aerodynamic performance calculation tools can be efficiently and effectively utilized for realizing improvements to vehicle performance, thereby enhancing customer satisfaction and societal acceptance. These tools include Computational Fluid Dynamic analysis (CFD) which further includes visualization techniques, shape deformation, DOE, and optimization methods, among others.
