The i20N N may have gone off sale in Europe but its still on sale in Australasia.

And if the spaceframe is so cheap and easy, Hyundai still dont build one due to:

"...the running cost. It’s maybe OK to build a car for €345,000 euros, but maybe on those €345,000 cars, if a door costs €10,000, this is not acceptable in the customer world. And this is really what we need to pay attention to. What will be the price for the dampers? For the under-protection of the car? We consume all those parts quite a lot on Rally2. And we have to be cost efficient."

That's the problem with all of this. It's all "he said that she said that somebody in the next street heard that ......"

We're relying on sports journo's with no technical background relaying what the FIA publicity people say. The actual technical regulations are often hidden from us because they're in things like homologation application forms that are only available to manufacturers. Without direct sight of those rules it's all guesswork - and pretty annoying!

It is (annoying). The only public regulations are the specific regulations but they do not include much technical details, mainly instructions for the user of the car which parts of the car has been homologated for rally use, how an original part can be modified etc.

Anyway, here is what the regulations said for 2011. In 2011 the idea was to use the same basic car for both regional and wrc rallies, but the car was too expensive for regional rallies.

2011 HOMOLOGATION REGULATIONS FOR SUPER 2000 KIT-VARIANT (RALLIES) / WRC
https://acrobat.adobe.com/id/urn:aai...6-2654d73f06f0

7.1 The following parts may be homologated in the Super 2000 Rally Kit Variant (VK-S2000-Rally) under the following conditions: PAGE 4 (7.1.1 Engine pages 5-11)
This part is probably when using a production engine.

7.3 Only for a WRC Type car, the following parts may be homologated: PAGES 18-19
These are the parts that only WRC cars can use.

APPENDIX: ENGINE, PAGES 33-39
Global Race Engine.

Here is the M-Sport Ford Fiesta regional rally car (RRC). Regional rally cars were not an official name for the car but used by M-Sport. Note that it had a 30 mm restrictor compared to the 33 mm restrictor for the WRC version.
