From Wikipedia, the free encyclopedia

General Motors has embraced the sharing of automobile platforms globally, although the company currently uses the term architecture rather than platform.

Traditionally, General Motors used letters from the latin alphabet to designate long-running vehicle families aimed at similar market niches. For example, the E-body Oldsmobile Toronado personal luxury coupe was redesigned significantly through four generations from 1966 through 1992, but retained the same letter designation throughout.

The chassis identification can generally be found as the 4th letter of the Vehicle Identification Number. GM also uses the letter designations to identify service manuals, owner manuals, and other publications. Frequently, the letter designations were used in mainstream automotive reporting and were familiar to customers, especially in the case of car families that were visually similar, such as the J-bodies.

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 front drive A-body was new design. In other cases, GM has used varied letter designations for similar products. The modern G, H, and K platforms are reported to be closely related, but GM has given different letter designations to various models.

In the 2000s, GM began using a more explicit platform naming scheme based on the greek alphabet. However many latin letter-designated products are still being sold.

Current and Historical platform applications

As mentioned above, GM used platforms to make a hierarchy of models aimed at different market segments. The following table attempts to place each shared platform in context. As General Motors has integrated worldwide operations, platforms are now shared globally.
