A non-linear stiffness actuator for a suspension corner employed in a vehicle includes an actuator housing and an actuator shaft configured to transmit an actuator force to the road wheel. The actuator also includes a primary elastic member assembly arranged between the actuator housing and the actuator shaft and configured to exert a primary elastic member force along the actuator shaft. The actuator additionally includes a secondary elastic member assembly configured to exert a variable secondary elastic member force acting between the actuator housing and the actuator shaft. The variable secondary elastic member force is configured to selectively contribute to and subtract from the primary elastic member force to thereby facilitate the non-linear stiffness of the actuator. A vehicle having such a non-linear stiffness actuator is also provided.
