Does the size of a bus's frontal area affect the aerodynamic drag it experiences when moving?

Question

DentroTest · Accepted Answer

Aerodynamic drag is the force exerted by the air opposing the vehicle's forward motion. This force depends directly on several key factors: the air density, the aerodynamic coefficient of the body (Cx), the square of the speed at which the vehicle is traveling and the frontal area (the projected area that strikes the wind). On heavy and bulky vehicles such as buses, a large frontal area displaces a large mass of air, which noticeably increases the resistance to forward motion and raises fuel consumption. Therefore, the frontal area does decisively affect that resistance.
