WebAerodynamics is the science of how air flows around and inside objects. More generally, it can be labeled “Fluid Dynamics” because air is really just a very thin type of fluid. Above slow speeds, the air flow around and through a vehicle begins to have a more pronounced effect on the acceleration, top speed, fuel efficiency and handling. Webcurve is below the VPI. A sag curve occurs when the arc is above the VPI. Typically, vertical curves are symmetrical.
