A removable, deformable energy absorbing steering wheel rim 5 is maintained in a rigid state under normal conditions by a number of wheel rim core link rods 4. Under impact during accident conditions the wheel rim core link rods 4 are retracted by a number of electro magnets (8 see fig 1) to allow the wheel rim 5 to deform in an energy absorbing manner by means of energy absorbing flexible sections of wheel rim core 3, an energy absorbing elastic wheel rim outer sheath 10 and other external energy absorbing components, namely an energy absorbing wheel rim restrictor fin 11 and an energy absorbing instrument cluster hood 12. Removing a number of withdrawable wheel rim retaining pins 7 allows a number of detachable wheel rim cradles 6 to be removed releasing the steering wheel rim 5 from the wheel hub 1.
