Noted for its four bi-parting side doors that open to provide a clear aperature of 55.5 inches, the structure of the Element eliminates the B-pillars by reinforcing and enlarging the side sills, floor and roof cross members, and providing five bulkheads per side. The rear door structure have a reinforced vertical beam and, when closed, connect to the body side sill via a hook and catch system, effectively creating a B-pillar. The rear-hinged rear side doors can open only after the forward doors.
