Abstract: Disclosed is a hydraulic energy absorbing bumper system for vehicles that includes a bumper with two variable stroke hydraulic buffers affixed to the ends. Both the stroke and the resistance of the buffers vary in response to the impact received by the bumper, however the resistance presented by either buffer during any given stroke is constant throughout the length of the stroke. Torsion hinges coupling the buffers to the bumper allow the buffers to stroke unevenly during oblique impact yet remain parallel. The bumpers are hydraulically interconnected so that the total energy absorbed during uneven stroking in response to the oblique impact is the same as the total energy absorbed during a normal impact of the same velocity.
