I believe the Rio [DC] hatchback/wagon had no separate name in Europe (IIRC it was Rio5 in North America). Here it didn't, as it was the main model offered (the sedan was only briefly sold, and much less popular than the wagon/hatchback).
For the 2013+ cee'd, I'm finding JC on wikipedia. What do part sites report? I'm seeing [JC] for the hatchback and [JD] on the wagon on your searches from carter-cash
