Still going ahead. The new regs are to steer the entire sport away from production car manufacturers altogether.

Watch this question and answer. https://youtu.be/I6-oOz8aDxE?t=4779

"The reason you can't carry on with [Rally2] is because the manufacturers aren't making those cars anymore. The homologations will run out and nobody's making those cars. So you must go to a spaceframe - you'll be surprised at how cheap those will be if we do them in big production volumes and they won't cost a lot of money" - David Richards.

But there's no reason why there's a guide on 'how to build a production engine for the championship' if the rules are for using a production engine common to Rally2 that belong in Group A surely? All you need in the WRC2027 regs is a simple statement - "use an engine homologated in Group A".

Maybe it's the specs of 'the Rally2 engine as basis' as we quite often read, so might be able to be built in the small volumes. That's the key point, not the specs.

again... "how to build an engine for the championship" doesn't mean you can build it from scratch or that is entirely new. it's not. there are rules on how to build it, and those rules -even for 27- point to existing specs and production related piece. that's it. of course they have to write it in the paper. no way a tech regulation can write "look at the previous one". they have to state all the things.

to further clarify, this is from dirtfish:
Engine
The engine will run at Rally2 specification, generating 300bhp. There is some discussion of another engine alternative, with Mestelan saying: “For the Rally2 engine, it’s already decided, this is already validated by the World [Motor Sport] Council, this is one option. There is also discussion to introduce a production-based engine based on production cars. It has to be refined with our manufacturers to know if we will validate this concept or not in addition to the current one. The aim here is to achieve power at a lower cost. [...]

Really ? Hyundai now confirm theyll likely build a new i20 Rally2 for 2027 ...

Benoit Nogier, customer racing manager, told DirtFish: “We can re-homologate a complete car based on the current street car. We have now this opportunity and we still want to improve the car, we still want to move forward, even if it’s not confirmed at 100%, we will probably launch the development of big evolutions ready for 2027."

Based on that article i20 Rally2 is a great car on tarmac. How the hell they did so wrong with their top car this year?

There's no FIA source I can find directly saying they have to come from production runs nor be already homologated Rally2. All the language is 'base' and 'basis' as in tech spec and power-level philosophy. Until this is made clear I'll remain open to the possibility I can build 10 engines to Rally2 tech specs in my shed.

There's also the possibility that what goes for 2027/2028 isn't the long term. Because moving away from relying on manufacturers building cars to relying on manufacturer to power the new cars makes 0 sense.

DR's point is the i20 N went out of production a few years ago. They can and probably will extend the homologation, but that is hardly a boon for WRC unless it becomes a historic championship.
