The 3H closed body structure of Chery A5 is highly integral, with firm frame, chassis connection, roof and support structure. As the intensity between each connecting rod is high, with little deformation, and there is supporting seat for the specially reinforced steel of B pillar, the body can bear the pressure from top to keep the frame stability. The side wall (A, B and C pillars) and front & rear bottom boards are of super strong structures, which can accommodate to the side collision well.
