Probably not 100%, but I'd wager that the US platform has closer bloodlines to the Euro/JDM platform as supposed to EUCD.

Platforms have an impact on overall interior/outside dimensions, but it's far from the deciding factor from a dimensional perspective.

For example, behold the 2004 Mazdaspeed Atenza A-spec:
