LIST OF GM PLATFORMS

General Motors has embraced the sharing of automobile platforms globally, although the company currently uses the term ''architecture'' rather than ''platform''.
Traditionally, GM platforms were long-running vehicle families aimed at similar market niches. For example, the E-body Oldsmobile Toronado lasted through four generations from 1966 through 1992, but retained the same name throughout. Customers began to use the platform names as well. For example, many economy car owners called their cars J-bodies rather than the multitude of different names used by the various GM divisions.
In some cases, the name was retained for a market segment even while the architecture diverged radically. In 1982, the A-body switched from rear to front wheel drive. The former chassis continued, now with the G-body name, while the new A-body was all-new.
