What is?
is a mathematical parameter drag coefficient determined by wind tunnel tests and experiments decline.

Function
It can be used to calculate the air resistance during running of automobiles. Drag coefficient depends on the size of shape of the vehicle. The greater the drag coefficient, the greater the air resistance. By this important parameter, can effectively reduce the air resistance of the cars, the automobile speed smoothly, and reduce fuel consumption. Known raindrop minimum drag coefficient is about 0.05, while today’s automotive drag coefficient typically between 0.3 to 0.5.

Did you know?
the vehicle is traveling, to overcome the resistance of the resistance loss of organic elements, generated by the tire rolling resistance (also called channel resistance) and air resistance. With the speed increase of the air resistance is becoming the main traveling resistance, than when the vehicle speed of 200km / h, the air resistance accounts for almost 85 percent of all of the traveling resistance. The resistance of automotive appearance is the most important source of air resistance. Exo vacuum zone created by the resistance from the rear of the vehicle, the greater the vacuum zone, the greater the resistance. In general, good resistance to San Xiangshi sedan smaller than the hatchback and MPV.
