The Mazda C platform is an automobile platform for midsize cars. It has was derived from the Mazda G platform used in the Mazda Capella/626.
The CA platform was developed for Mazda's new upmarket Eunos marque. Just two vehicles used this platform.
With the demise of the Eunos brand in Japan, Mazda continued selling a slightly refreshed Eunos 500 as the Mazda Lantis.
CG was very closely related to its predecessors. It was used for the replacement Mazda Capella for a short time.
