The requirement on the automotive industry to continually improve vehicle safety and fuel economoy while reducing the costs and environmental footprint are the driving factors in automotive design and material selection. These goals are conflicting in nature and solutions will be realized by innovative design, advanced material processing and advanced materials. Advanced high strength steels are engineered materials that provide a remarkable combination of formability, strength, ductility, strain-rate sensivity and strain hardening characteristics essential to meeting the goals of automotive design. These characteristics act as enablers to the design and manufacturing aspects of the process. Cost and mass increases are the primary concern of simultaneously achieving the increased safety and fuel economy goals. The ULSAB-AVC program demonstrates a solution to these conflicting goals and the advantages that are possible with the utilization of the advance high strength steels and, like the ULSAB program, a predictor of the material content of future body structures. The ULSAB-AVC program focused on the development of steel applications for vehicles for the year 2004 and beyond. In its execution, concepts were developed for the popular European C-Class, or so-called Golf Class, and the North American Midsize Clas, which is the target for the PNGV program, hereafter refered to as PNGV-Class vehicle. Therefore, the vehicle body structures employ the unique advantages of advanced steel grades, which provide heightened strength with excellent part forming. ULSAB-AVC vehicle body structure uses 100 percent high-strength steel gades, of which over 80 percent are advanced high-strength steels. These steels are combined with the most advanced manufacturing and joining technologies. The ULSAB program results demonsrated a 25 % reduction at no cost relative to the range of 32 benchmark vehicles of the same class.
