Is it not just good business sense for manufacturers to alternate between brands? VAG switching from VW to Skoda, PSA switching from Citroen to Peugeot and its not out of the realms of possibility that Hyundai will do the same with Kia. After all the WRC is a promotional shop window. It doesn't really matter to me what the big manufacturers do with their brands as long as they don't leave WRC (or rallying) entirely.
