off course i couldnt find the link today, but renault brought a "racing version" of the R5 3E during its release and literally said they talked to fia about rallying that car but 'evs were still not on the table' in wrc's mind. i swear something along these lines happened but i cant find. maybe later on my notebook. i found this one, but this is not the one i've read. https://dirtfish.com/rally/wrc/renau...lying-by-2025/
based on some talks from that time i got my suggestion of having rally2 as top class but only for privateers and constumers, factory teams must run hydrogen, hybrid or electric rally2s (bop)
