UltraLight Steel Auto Closures Overview

The UltraLight Steel Auto Closure (ULSAC) Program demonstrates the effective use of steel in producing lightweight, structurally sound automotive closure panels that are manufacturable in high volume. ULSAC began as a concept development program, producing innovative concept designs for doors, hoods, decklids and hatches that are up to 32 percent lighter than benchmarked averages and 10 percent lighter than best-in-class, while meeting stringent structural performance targets.

The ULSAC Program was commissioned by an international consortium of 31 sheet steel producers to assist their automotive customers with viable lightweighting solutions. The ULSAC Consortium contracted Porsche Engineering Services, Inc. (PES), to provide design and engineering management for both the concept and validation phases of the program.
