Abstract: A powertrain mount includes a resilient mount that is connected to a powertrain component by a connecting arm. The resilient mount is moveable by an actuator member relative to a structural member of a motor vehicle in an opposite direction to a predicted displacement of the connecting arm so as to reduce the displacement of the powertrain component relative to a fixed point on the motor vehicle when the predicted displacement occurs. This reduces the final displacement of the powertrain component relative to a fixed point on the motor vehicle when the predicted displacement occurs and allows the use of a softer resilient mount than would otherwise be the case.
