Drag

Drag (also known as air resistance) is the force that opposes the motion of a car through the air. The higher the drag, the more power is needed to accelerate your car to a certain speed and maintain it. Drag is created by the displacement of air around the car and the frictional impact of that air on its surface. It counteracts your car's direction of motion and is dependent on its speed, front face area, the drag coefficient (cd), and the density of the air. The typically aerodynamic body style of our cars, allied to narrow shut lines, reduces air swirl, helping produce low levels of drag and delivering lower fuel consumption. The key influencing factor, though, is the car's speed, as a doubling of speed quadruples the drag.
