That's just a new R4 name under the new system.

Because R4 would be too confusing with Rally4, which now has the R2 and R3 cars. It's a mess...
Rally1 cars -> WRC spec -> RC1 category
Rally2 cars -> R5 spec -> RC2 category
Rally2-Kit cars -> R4 spec -> RC2 category
Rally3 cars -> New 4WD spec -> RC3 category
Rally4 cars -> R2 spec -> RC4 category
Rally5 cars -> R1 spec -> RC5 category
New Fabia road car is coming in the spring. Hopefully we’ll see a concept Rally2 car soon after and the first public tests..

The new car is likely to be prettier than the current Fabia but also wider so it may lose that chunky chiselled look of the current R5 car that i rather like.
