Passive safety features include: crumple zones in 1957 (
vehicle body structure absorbs the force of impact); collapsible steering column (prevents the steering column from protruding into the cabin during accidents),
strengthened occupant cell enhanced
occupant protection during severe impacts (rollovers); pre-accident seatbelt tensioning (tightens seatbelts prior to impact), and sandwich platforms (allows the engine to slide under the
occupants in a head - on collision).
