The Ultralight Steel Auto Body (ULSAB) Programme is an intensive, multi-phase study to demonstrate steel's capability to reduce substantially the weight of a vehicle's body structure and, at the same time, ensure safety with improved comfort and driving performace, all at affordable cost. ULSAB resulted in the design and engineering of a lightweight, efficent steel body structure that achieves impressive mass savings and significant performance improvements, while retaining affordable cost to manufacture. ULSAB achieves:
- Mass savings of 25% over the benchmark at no cost penalty
- 80% improvement in torsional rigidity
- 52% improvement in bending rigidity
- 58% improvement in first body mode
- Meets all mandated crash requirements
