VSS-T, or Vehicle Strategy Set – Truck, is the name of an upcoming automotive architecture that will underpin next-generation, rear-wheel-drive and rear-wheel-drive-based four-wheel-drive pickup trucks and sport utility vehicles (SUVs) from General Motors.
Contrary to its name, the VSS-T will also underpin sport utility vehicles built using a body-on-frame construction. Meanwhile, unibody SUVs (technically crossover utility vehicles or CUVs) will ride on the GM VSS-S platform set.
It is also probable that VSS-T will underpin body-on-frame vans.
Overview
The VSS-T platform, or more appropriately the VSS-T vehicle set, is part of GM’s objective to consolidate platforms, reduce complexity, and simplify engineering and manufacturing processes in order to realize significant cost savings and enable the company to deliver better-differentiated designs more quickly to customers around the world. In that capacity, the VSS-T platform would replace all of GM’s rear-drive, longitudinal-engined, body-on-frame platforms with a single set. This single set that will, in turn, have several subsets for differently sized vehicles.
GM’s vehicle sets will employ common components and structures, which will save engineering, purchasing and tooling costs. In theory, the undertaking will also enable GM to better tailor individual models to regional markets and specific sectors. For instance, a Chevrolet Silverado full-size pickup truck would share a significant amount of basic parts but not sheet metal with the GMC Canyon mid-size pickup truck.
Development
Development of the Vehicle Set strategy was started in the 2013-2014 timeframe by GM CEO Mary Barra when she headed GM’s product development department before succeeding Dan Akerson as CEO in January 2016. The project is currently lead by GM Executive Vice President of Product Development, Mark Reuss.
Subsets
It is believed that the VSS-T set will have several subsets to underpin differently-sized vehicles. It is currently unclear what these subsets will be.
Vehicle Applications
VSS-T will underpin future rear-drive or rear-drive-based four-wheel-drive pickup trucks and SUVs with a longitudinal powertrain orientation. The first vehicle on VSS-T is scheduled to be launched by the 2020 calendar year.
Here are the vehicles we expect VSS-T to underpin:

- Future Chevrolet Tahoe (sixth generation; full-size SUV)
- Future Chevrolet Suburban (13th generation; extended-length full-size SUV)
- Future Chevrolet Colorado (third generation; mid-size pickup truck)
- Future Chevrolet Trailblazer (for markets outside North America) or potential future global midsize body-on-frame SUV
- Future Chevrolet Express (second generation; full-size van)
