A spokeswoman for Buick said that the Encore GX will be built on a Buick-specific platform not shared with any other brand, including the seemingly related Chevy Trailblazer. GM hinted Wednesday that the common components were flexible enough to scale up or down within vehicle classes and between brands and give GM unique architectures for seemingly related products. VSS-S will be used for crossovers including the Encore GX and Trailblazer, and VSS-T will underpin body-on-frame vehicles such as the Sierra 1500 and Yukon. The VSS-F platforms will be used for front-drive cars such as the Malibu.

The VSS-R platforms will be the basis for rear-wheel drive cars such as the next-generation Camaro. VSS will serve as the basis for four main platforms that will use similar components, such as HVAC, electrical architecture including infotainment, and substructures. Last year, GM announced that VSS and dedicated EV platforms would serve as the basis for more than 75 percent of its vehicles early next decade. The components that feed into four main platforms, which should eventually include front- and rear-wheel drive vehicles, crossovers, and body-on-frame trucks and SUVs, were announced five years ago as a cost-saving measure that could save GM billions in production and development expenditures. The Trailblazer and Encore GX are the first vehicles to arrive with GM's new unified common components, dubbed Vehicle Set Strategy.
