Due to stricter emissions standards of carbon dioxide production, automobile manufacturers are forced to search innovative solutions. An eventuality to reduce emission production is to reduce the weight of a car body. This weight reduction can be achieved by replacing material used in production of outer car body parts. The subject of this article is use of dual phase steel with tensile strength higher than 500 MPa for outer car body parts. Stampings used in experiment come from current models of ŠKODA AUTO, a.s. Due to lack of experience, material cards and feasibility of these parts were evaluated. Attention was paid primarily on crack initiation, wrinkling and springback.Keywords: Sheet Metal Forming, High Strength Steel, Outer Car Body Parts, Dual-Phase Steel, Springback
