An awful lot of why they are what they are is all right in those regs.
IE the limitations...

So your trying to tell me every WRC engine is singly describe by one set of rule (i.e. Limitations). Every manufacture has their own take on the engine regulations that why you see VW dominating because their engine is much strong than the rest. The formula one has limitations like the WRC and I don't see Renault and Mercedes with the same engines, likewise with Citroen, M-Sport, VW, Etc. The 2007 Subaru WRC 2.0L boxer looks, sounds and performs just like the Citroen C4 WRC 2.0L I4...... I don't think so.
