Mazda G platform
Prior to 1981, Mazda coded the rear wheel drive Capella platform as "S1" in the VIN code. This chassis was dropped for the Capella, but retained (in a modified form) for the RX-7 as the Mazda F platform.
GC was Mazda's first front wheel drive midsize car platform. Available body styles were two-door coupé, four-door sedan, and five-door hatchback. The Ford Telstar hatchback version was called the TX5, there was no Telstar version of the coupé. Production was in Japan, with local assembly in Australia (as a Telstar only), New Zealand, Taiwan and South Africa where the model continued in production until 1993.
The updated GD platform was introduced in 1987 in Japan and later elsewhere. It spawned a station wagon variant, the GV. Production in the United States was started at the AutoAlliance International plant in Flat Rock, Michigan.
The Japan-market Mazda Capella never used the GE platform. Rather, a new model (the Mazda Cronos) was introduced alongside the Capella, while the Capella continued on with the GC platform until 1993 and was then moved to the CG platform for 1994 through 1997. As Ford and Mazda shared engineering technologies, the GE platform is related to the Ford CDW27/CD162/CD132 used for the Ford Mondeo and Jaguar X-Type.
Note that Mazda6 models assembled at the joint-venture AutoAlliance International plant in Flat Rock, Michigan and these do not follow Mazda's system of using the platform code as characters four and five of the VIN. American-built Mazda6s use the "1YV" prefix on the VIN. See Ford CD3 platform.
The rear multi-link suspension is remarkably similar to the "E multi-link" found in the HC platform. Although also similar to Ford's own design, Mazda engineers said this is a revival of the "E multi-link".
Introduced in 2008, it is a retuned and revised version of the preceding GG chassis. See Ford CD3 platform.
Introduced in 2012, it is the platform used on the third-generation Mazda6.
