  OBJECTIVES • Reducing Drag •Influencing the way that how a car cuts through air • Reducing wind noise • To provide vents for engine cooling ,etc.. • Preventing undesired lift forces at high speeds. • For providing better downforce for good traction.

  DRAG • Also calledas air resistance • It depends on velocity • Advantages when reducing drag 1. Better fuel economy 2. Good performance

  Types of drag •Pressure drag • Friction drag
