The Light Truck Structure (LTS) Program explores the benefits of steel lightweight design in the high-volume light truck market. The American Iron and Steel Institute (AISI) commissioned Porsche Engineering Services, Troy, Michigan, to develop this design concept. The Program applies the clean-sheet approach used by the Ultra Light Steel Auto Body (ULSAB) to demonstrate significant weight and cost savings for a mid-size car body-in-white (BIW). The LTS goes one step further in examining both the body and chassis frame elements for compact light trucks. This concept specifically capitalizes on the design, performance and manufacturing strengths of steel.
