The center of gravity is a geometric property of any object. The center of gravity is the average location of the weight of an object. For a vehicle this is the point from which all forces created at the tires react too. It can be described as a certain point in the vehicle on an X, Y, Z coordinate. If you suspended a vehicle from this point it would rotate in all directions freely. A car’s weight distribution is often described by its center of gravity location. For example, a 60% rearward center of gravity would describe a car with 60% of it’s weight on the rear tires and 40% on the front.
