I can see both sides of the argument here (I own an AWD Subaru) but would still prefer to see the spectacle of RWD - especially on tarmac.
Rallying producton based cars would be good, but leads to the old homologation/cost issue and restricts manufacturers.
If rally does go through another evolution due to the speed and safety issues (group B all over again), I'd like to see RWD in larger cars using larger naturally aspirated engines (the formula advocated above is just one possible permutation - bigger engines would be even better - say 3.5 litre V6's
)
You just have to look at all the classic car tarmac rallys (eg in Australia: Targa Tasmania or Classic Adelaide) to see how exciting RWD can be. Imagine that with the top teams and drivers - wooo hoooo
