Mazda previously used a number of different marques in the Japanese (and occasionally Australian) market, including Autozam, Eunos, and Ẽfini, which have since been phased out. This diversification stressed the product development groups at Mazda past its limits. Instead of having a half-dozen variations on any given platform, developers were asked to work on dozens of different models and consumers were confused as well by the explosion of similar new models. One of the oddest sub-marques was M2, used on three rare variants of the Eunos Roadster (the M2-1001, M2-1002 and M2-1028) and one of the Autozam AZ-1 (M2-1015). M2 even had its own avant-garde company headquarters, but was shut down after a very short period of operation.

Today, the former marques exist in Japan as sales channels (specialized dealerships) but no longer have specialized branded vehicles. The Carol is sold at the Autozam store (which specializes in small cars), but it is sold with the Mazda marque, not as the Autozam Carol as it once was.

In early 1992 Mazda planned to release a luxury marque, Amati, to challenge Acura, Infiniti, and Lexus in North America, which was to begin selling in late 1993. The initial Amati range would have included the Amati 500 (which became the Eunos 800 in Japan and Australia, Mazda Millenia in the U.S., and Mazda Xedos 9 in Europe), a luxury sports coupe based on the Mazda Cosmo and the Amati 1000 (a rear-wheel drive V12 successor to the Mazda 929). The Amati marque was eventually scrapped before any cars hit the market.

In Europe, the Xedos name was also associated with the Mazda Xedos 6, the two models were in production from 1992 until 1997. The Xedos line was marketed under the Mazda marque, and used the Mazda badge from the corresponding years.
