Fig. 8.3. Mazda 6 car body frame: 1 – body frame; 2 – front bumper reinforcement; 3 – casing panel
The body frame (Fig. 8.3) is designed to increase rigidity and reduce impact on the body, thereby increasing safety. Crumple zone, H-shaped design (triple H-shaped construction), absorbs the impact energy and prevents injury to passengers. The steel bumper reinforcement also serves to increase safety. The use of a polymer casing panel improves repairability.
