Maybe.
But it seems they're putting a lot of work into the Rally2 car only to ditch it and spend considerably more developing a WRC27 spaceframe car.

Their car is homologated until 2032, so that's a lot of years for competing with that car. Also if WRC27 fails, which I'm still somehow convinced it will (no matter if we got 2 new teams in the championship), that car would be valid I think for further years.
