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.
