ultralights by voestalpine are steels optimized for a wide range of applications. The "best of" compilation shows how much weight can be saved in only a few components. The SLIMulations compare the original steels of actual components with voestalpine steels, and corresponding crash tests are simulated. The baseline represents a 5-star-safety mid-size car (source: NCAP).
