Description

The mass supported by this WheelCollider.

Vehicle simulation uses the sprung mass model where it would decompose the full mass of the car supported by all wheels at once into a set of sprung masses supported by each individual wheel. Then it would work out all the suspension and tire forces for each wheel-mass pair and, as the last step, it would integrate all forces applied to the vehicle's body. In the simplest case of a perfectly symmetric car with four wheels, all sprung masses would be equal to a quarter of the car's mass. This property is automatically computed based on the car's configuration.
