A method and vehicle control system for controlling stiffness of at least one support structure of a vehicle includes at least one of an acceleration sensor, a braking sensor and a corner sensor for providing a driving condition of the vehicle. A controller obtains information from the sensors to determine the driving condition and control the stiffness of a support structure of the vehicle. A magnetic field generator provides a magnetic field to control the stiffness of the support structure having a magnetorheological fluid or elastomer. An electrical source provides electrical current to a support structure including an electrorheological fluid or a support structure including a meta-material. When a vehicle collision is predicted no energy is provided to the support structure to minimize the stiffness and maximize energy absorbance by the support structure in a collision.
