GM VSS-R Vehicle Set Platform
VSS-R, or Vehicle Strategy Set – Rear, is the name of an upcoming automotive architecture that will underpin next-generation, rear-wheel-drive and rear-wheel-drive-based all-wheel-drive cars from General Motors.
At the current moment, it is unclear whether VSS-R will also be capable of underpinning crossovers (CUVs) built using a unibody construction. It is likely that those vehicles will ride on the GM VSS-S platform set.
The VSS-R platform, or more appropriately the VSS-R 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-R platform would replace all of GM’s rear-drive, longitudinal-engined car 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, the Cadillac sedan lineup sold globally would share a significant amount of basic parts but not sheet metal with each other and with the Chevrolet Camaro.
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.
It is believed that the VSS-R set will have several subsets to underpin differently-sized vehicles. It is currently unclear what these subsets will be.
VSS-R will underpin future rear-drive or rear-drive-based all-wheel-drive cars with a longitudinal powertrain orientation.
Here are the vehicles we expect VSS-R to underpin:
Future Chevrolet cars:
- Future Chevrolet Camaro (seventh generation)
- Potential future Chevrolet SS sedan successor
Future Cadillac cars:
- Future Cadillac CT3 (second generation; successor to first generation CT3, itself a successor to Cadillac ATS)
- Future Cadillac CT5 (second generation; successor to first generation CT5, itself a successor to Cadillac CTS)
- Future Cadillac CT6 (second generation; successor to first generation CT6 possibly named Cadillac CT7)
GM VSS-R will succeed longitudinal-engined, rear-drive and rear-drive-based all-wheel-drive car platforms, including:
- GM Alpha platform, which underpins:
- GM Alpha 2 platform, which will underpin:
- GM Omega platform, which underpins:
Other GM Vehicle Sets
VSS-R will join three other General Motors vehicle sets, including:
