But you are not correct. You can be together champion in WRC2, WRC2 Challenger and also WRC2 Master.
Almost - one may be a WRC Master and WRC2 Challenger Champion on separate entries (which still sounds ridiculous), but not a WRC2 Master and WRC2 Challenger (which sounds ridiculous was my point).
Tarmac rallies are part of the WRC challenge for drivers.
And having the Championship in a major European capital city will bring great publicity to the sport there.
From beginning it is mainly about Rally2 car. But still there is question how 2027 will looks like in general...
