The performance and consumption, driving behavior, and comfort of a car are significantly influenced by its aerodynamic properties. A low drag coefficient, for example, is essential for achieving ambitious fuel consumption targets. This book is aimed at students of mechanical engineering, automotive engineering, physics, and other related fields, as well as automotive engineers in industry, research, and education, and in technical monitoring associations and authorities. It is intended for vehicle technicians, designers, testing and calculation engineers, as well as aerodynamicists from other industries. Additionally, it targets designers, specialized journalists, and automotive enthusiasts passionate about technology.
