The UltraLight Steel Auto Suspension (ULSAS) Program is an initiative by a global consortium of 34 steel companies from 15 countries, who united to communicate the attributes of modern steel to their automotive customers. It is a showcase for the best automotive design technology that can be brought to bear on today's highly complex technical challenges, and is a primer on understanding and exploiting the properties of steel as they apply to automotive suspensions.

The objectives of the ULSAS study were to reduce the mass of a new steel design by at least 20 percent versus benchmarked conventional steel suspensions, without a cost penalty; and, to match the mass of a benchmarked aluminum system with a steel suspension system, while demonstrating a cost savings of at least 20 percent.
