Over the last several decades aerodynamic development has become an increasingly important component of the automotive design process. Reducing the force required to push a body through the air has tangible benefits for fuel efficiency. When done right, it also has a side benefit of reducing the amount of wind noise heard in the cabin while driving. Traditionally, the wind tunnel has been one of the most important tools in this process, but taking a car into a wind tunnel is and expensive and time consuming process so Ford has developed a way to bring the tunnel to the cars.
