The demand for economic lightweight design for a body-in-white intensifies the competition of materials. In order to meet the market's requirements the steel industry started to develop new steel grades. The high and ultrahigh strength steel grades offer the possibility to reduce the components' weight by reducing the material gauge. The development of a body-in-white with the intensive use of high strength steel was realized with the ULSAB-project in 1998. The weight reduction was achieved by a reduction of the material thickness. The reduction of the material gauge in combination with an upgrading of the material grade was used intensively till the technical boundary conditions of the conventional manufacturing technologies were obtained. These results were brought forward to further projects and were presented in ULSAB-AVC, a lightweight design concept with a holistic approach. Such an entire approach is necessary to confirm that the fuel consumption will be sustainably reduced, so that the future emission requirements will be adhered. Both projects presented intensive use of modern multiphase steel and innovative manufacturing and joining technologies. The NSB - NewSteelBody boasts the same goals and advances the innovative use of modern steel grades and technologies. In comparison to ULSAB and ULSAB-AVC the NSB is a further step in the intelligent use of closed section profiles and conventional shell design. Overall, the NSB concept is the future basis for a lightweight construction with good performances as an important cost efficient alternative to aluminum cars in areas where maximum weight reduction is the target.
