Another interesting point in Hyundai’s announcement is that Solberg will do only recce and PR activities in Japan (whereas he was supposed to do the rallye normally).
They could put Sordo to maximize the result but, if the new driver is not a current manufacturer driver, it could be even more worthy to make him drive in Japan to get some habits.
As the publication of the entry list is very soon, it may explain why the announcement of splitting with Solberg has been done now and we may have the name of his replacement very soon.
