The Mazda D platform is an automobile platform for subcompact cars developed by Mazda. It has been used for a number of Mazda vehicles, and also by models produced by Kia Motors and Ford.
The Autozam Scrum keicar sold by Mazda is a badge-engineered Suzuki Every. Therefore its DL (1991–1995) and DG (1999–present) codes do not refer to a Mazda platform.
A minor update to the DB.
The "DY" is a subcompact platform co-engineered with Ford which uses it as their B1 platform.
The "DE" is a subcompact platform co-engineered with Ford which uses it as their B3 platform.
