Using the advanced ring-shaped reinforcements throughout the Subaru Outback bodyshell enhances collision safety and resistance to impacts from all directions. In addition, the newly adopted sub-frame mounting system contributes to an enlarged front-end crush zone, further improving occupant protection.

During a front-end collision, the new front sub-frame deforms in a controlled manner and pushes the power unit to the rear and downwards. As a result, the rearward movement of such a large mass dissipates impact energy and assists the efficient absorption of collision energy by the main body structure.

To enhance side-impact protection, ultra-high-strength steel plate (980 Mpa level) is used for the B-pillar and side sill structures to improve the local cabin area rigidity. In addition, two door impact beams are placed within each front and rear door. By optimally positioning the beams in relation to the door's internal structure, a sufficient crush space is ensured to minimise intrusion. Furthermore, a 'door catcher' is fitted to prevent the bottom of the rear door from deforming into the cabin - particularly in rear impacts.

Despite the relatively short rear overhang, the Subaru Outback's structure is optimised so that rear impact energy is efficiently absorbed by controlled and gradual crushing of the rear sub-frames.
