MIT scientists and colleagues have reported new mathematical and experimental work for predicting where aerodynamic separation will occur. Aerodynamic Separation occurs. for instance, when a car accelerates up and down a hill then slows to follow a hairpin turn: the airflow around it cannot keep up and detaches from the vehicle. This aerodynamic separation creates additional drag that slows the car and forces the engine to work harder. The same phenomenon affects other vehicles as well. (source: web.mit.edu)
