Mazda Motor Corporation, working separately with Nippon Steel & Sumitomo Metal Corporation and JFE Steel Corporation, has developed the world’s first cold-stamped vehicle body parts made from 1 310 MPa-class high-strength steel. The parts are used in Mazda’s new-generation Skyactiv vehicle architecture, which will underpin upcoming models, starting from the all-new Mazda3. High-strength steel enables automakers to make parts from thinner sheet metal, while retaining the necessary yield strength. This results in a lighter vehicle body, which contributes to improved handling stability and fuel economy. A strong body is also essential to ensure crash safety performance.
