The all-new architecture incorporates a new design that not only improves distortion rigidity by 16 percent, it also incorporates a 30-percent increase in the use of ultra high-strength-tensile steel to improve collision energy management. High-strength steel also allows the suspension to work optimally and reduces weight. Ultra-high strength tensile sheet metal has also been applied to the outer door panels for the first time in the company’s history. In addition, anti-corrosion steel was applied to 70 percent of outer frame and floor structure.
New hot stamping and roll forming methods have also been applied to impact members, which provide added strength, reduces the number of body parts and makes the architecture lighter. The amount of structural adhesives has also been increased significantly for improved body rigidity, crashworthiness and durability.
