List of General Motors platforms
The American-based international automotive conglomerate General Motors (GM) underpins its many vehicle models with various platforms. These platforms are established sets of axles, suspensions, and steering mechanisms which fit various bodies and powertrains from various marques that GM owns.
From the early twentieth century, a Latin letter-based naming scheme was used to designate platforms,[1] which were aimed at vehicles under different brands that served similar niches of the market. For example, the B platform was the base for fullsize, rear-wheel drive (RWD) sedans and wagons from 1926 to 1996. This platform underpinned vehicles made by Buick, Cadillac, Chevrolet, Marquette, Pontiac, and Oldsmobile. During the 1970s and 1980s, GM introduced many new front-wheel drive (FWD) platforms for the first time, such as the FWD C platform introduced in 1985. Despite being mechanically very new and different, it kept the same name as the RWD C platform for the sake of consistency, as most of the models remained the same, such as the Oldsmobile 98. For most of these platforms, the platform name is the fourth character of a vehicle's VIN, with a notable exception being trucks, for which it is the fifth character.[2]
At the outset of the twenty-first century, General Motors' approach to platforms changed,[3] and so did the nomenclature they use. Platforms themselves are now referred to by GM as "architectures",[4] and are now named according to the English-language names of letters from the Greek alphabet, such as the subcompact Gamma platform.[5] Today, many of the since-discontinued Latin letter platforms are informally called "bodies", such as "J-body", which refers to the J platform. In the 2010s, GM once again began to change platform nomenclature, this time to a four-character format: platform-generation-XX. An example of this is the D2XX, from the second generation of the Delta platform, hence the "D" and "2".[6]
All but three platforms listed here use a front-mounted engine, and those exceptions are noted in the 'layout' column.

- * These vehicles were/are not from GM brands, but rather were given license to a particular platform by GM, usually either from co-development or a platform nearing the end of its tenure.
- ** These platforms have active models, but no active models from any GM brands, and are thus considered former platforms for this list.
Future platforms
In 2015 GM announced their intention to shift all of their vehicles (with the notable exception of the eighth-generation Corvette) to four platforms by 2025. The following are those platforms, including the already-launched VSS-F:
Name | Layout | Introduction | Vehicles to be Underpinned | Notes |
---|---|---|---|---|
VSS-F | FWD/AWD | 2019 |
|
The eventual consolidated successor to the Gamma II, G2XX, E2XX, D2XX, P2XX, PATAC K, U IV, GM4200, and GEM platforms.
Slated to underpin all FWD GM cars plus subcompact crossovers by 2025.[16] |
VSS-R | RWD/AWD | 2023 |
|
The eventual consolidated successor to the Alpha and Omega platforms.
Slated to underpin all RWD GM vehicles by 2025. |
VSS-T | RWD/AWD | 2025 |
|
The eventual consolidated successor to the GMT platforms.
Slated to underpin all GM body-on-frame SUVs and trucks by 2025. |
VSS-S | FWD/AWD | 2024 |
|
The eventual consolidated successor to the D2XX and C1XX platforms.
Slated to underpin all GM crossovers (excluding those on VSS-F) by 2025. |
It is currently unknown whether GEM or a similar low-cost platform will be continued in some form as a subset of VSS.
EV platforms
Electric vehicle platforms are the only other exception to the forthcoming VSS consolidation.
BT1XX
BT1XX, standing for first generation battery-electric truck, is an upcoming electric body-on-frame truck and SUV platform derived from the GMT T1XX platform with RWD and AWD capabilities.[18] It is currently only slated to underpin the 2021 GMC Hummer, though it has not been clarified as to whether it is the only model for which the platform is to be used.[19] Speculation, however, as of May 2021, is that the all-electric Chevrolet Silverado will use this platform is it's been said that the all-electric Silverado will be built alongside the new GMC Hummer EV.
BEV3
BEV3, standing for Battery Electric Vehicle 3 and also known as Ultium, is to be the replacement for the current BEV2 platform.[20] Little is known about the nature of this platform, though it has been confirmed that it will underpin, among other models, a future Cadillac crossover.[21]
