Vehicle Set Strategy (VSS) is a series of four automotive platforms developed by American manufacturer General Motors for their vehicles as part of an effort to consolidate their platform usage for the present and future. GM eventually plans to have the VSS platforms underpin over 75% of their models, the exceptions being the BEV3 platform used for electric vehicles and specialty vehicles like the Corvette.
