Well I don't have any inside info either.

One of the quoted reasons for using C3 was that it was neutral so that none of the 3 teams get an advantage. Does that mean they had to ask Toyota and Hyundai now to get "permission" to test with Fiesta? (They probably don't mind since MSport is not a threat in either champ.)

On related note, did they need special FIA permission so it doesn't count as MSport "test days"? There was some controversy about this in 2017 when FIA made special ammendments to rules to keep Jipocar (Østberg) from extra testing "for MSport".
