A flexible optical impact detection sensor is mounted on an outboard portion of the front bumper for signaling an offset rigid barrier impact event to a forward corner of a motor vehicle and deployment of a small offset rigid barrier airbag mounted on the front rail. The airbag is attached proximate a distal end of a front rail. The flexible optical impact detection sensor, attached to a rear surface of an outboard portion of the front bumper, generates a signal upon a corner impact event, whereby a controller processes the signal generated by the impact detection sensor and electrically actuates an inflator upon a predetermined impact severity. The airbag in the inflated condition acts against the offset rigid barrier to generate a lateral force against the offset rigid barrier to push the motor vehicle away from the barrier and thereby redirect impact energy by lateral movement of the motor vehicle.
