Chronology
Predecessor

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.[1] 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.[2]

VSS-F

VSS-F is to be GM's primary front-wheel drive (F) platform, considered a successor to the Gamma, Delta, and Epsilon platforms. It is planned to underpin many subcompact to fullsize cars as well as GM's smaller crossovers in the future, a pattern established by the first models to use it, the Chevrolet Trailblazer and Buick Encore GX.[3] The platform can also be used for all-wheel drive vehicles.

Of the four, this platform has the most developed implementation plan, with three variants already established:[4] which are VSS-F A for minicompact cars (i.e. Chevrolet Spark), VSS-F B/C for subcompact and compact cars and crossovers (e.g. Buick Encore and Chevrolet Sonic), and VSS-F D/E for midsize and fullsize cars (i.e. Chevrolet Malibu and Impala).

Applications

VSS-R

VSS-R GM's planned rear-wheel drive (R) platform, considered a successor to both the Alpha and Omega platforms. Vehicles slated to be underpinned by this platform include the second generations of the Cadillac CT4, CT5, and CT6, as well as future models of the Chevrolet Camaro.[5][6][7]

VSS-S

VSS-S GM's planned secondary (S) front-wheel drive platform, also capable of all-wheel drive. GM intends to utilize this platform for vehicles ranging in size between compact and fullsize. Vehicles slated to be underpinned by this platform include the Buick Enclave and Chevrolet Equinox.[8]

VSS-T

VSS-T is GM's planned body-on-frame SUV and pickup truck (T) platform, considered a successor to the long-standing GMT platform and capable of all-wheel drive. It is to be capable of supporting midsize and fullsize truck dimensions, and will underpin both the fifth generation Chevrolet Silverado/GMC Sierra and the fourth generation Chevrolet Colorado/GMC Canyon.[9]
