Typically, when two vehicles share the same underlying platform, they will also have the same specs with regard to wheelbase length. However, that’s not the case for the 2021 Chevrolet Trailblazer and 2021 Buick Encore GX, which actually have different wheelbase lengths despite the fact both subcompact crossovers are based on the GM VSS-F architecture.
For those who may be unaware, VSS-F, or Vehicle Strategy Set – Front, is an automotive architecture used to underpin front-wheel-drive and front-wheel-drive-based all-wheel-drive GM vehicles. The VSS-F platform can more appropriately be called a “vehicle set,” as it is part of GM’s strategy to consolidate its various architectures in an effort to reduce overall production complexity and simplify engineering.
As such, the VSS-F vehicle set underpins both the 2021 Chevrolet Trailblazer and the 2021 Buick Encore GX. However, thanks to the flexibility afforded by these new vehicle sets, the two subcompacts have different wheelbase measurements, with the Trailblazer measuring in with a 103.9-inch wheelbase, and the Encore GX measuring in with a 102.2-inch wheelbase.
To note, both the 2021 Chevrolet Trailblazer and the 2021 Buick Encore GX are assembled on the same production line, specifically the GM Bupyeong facility in South Korea.
Going forward, the VSS-F vehicle set is also expected to underpin the next-generation Chevrolet Equinox and next-generation GMC Terrain. As we covered previously, GM President Mark Reuss previously underscored GM’s efforts to streamline its product offerings, with both the future Chevrolet Equinox and future GMC Terrain cutting the available build combinations from over 200, to 100.
“We will reduce total trim levels on Equinox and Terrain from eight to six, reduce engine variants from 11 to five, reduce build combinations from more than 200 to less than 100 per program, and see significant cost savings of an already paid-for architecture that took the mass out, helping us self-fund electrification programs,” Reuss said earlier this year.
