A » The drag coefficient (Cd) of a vehicle quantifies aerodynamic resistance, directly influenced by its shape. Streamlined designs with smooth, rounded edges tend to have lower Cd values, reducing air resistance and improving fuel efficiency. Conversely, boxy or angular shapes increase the drag coefficient, leading to higher energy consumption. Thus, optimizing a vehicle's shape is crucial for achieving better aerodynamics and performance.
