We could see a Mini Paceman become an R4 car, who knows?
What the FIA could do is to encourage the 1.6 turbo 4WD cars in like the Countryman/Paceman, then to stop any new homologations of 2 litre cars.
Then by allowing the 1.6 to have a lower minimum weight, the 1.6 cars in R4 become as fast.
All depends on how the FIA decide to do it, if they decide to do anything at all.
As rumour has is that R5 will become the top category of the WRC in time, and will they then want to keep R4 as the next category down?
1.6 turbo 4WD coming from Subaru ?
