The 2015 Red Bull Global RallyCross Championship is the fifth season of the Global RallyCross Championship. Joni Wiman is the reigning champion in the Supercars class and drives for the same team, Olsbergs MSE, as last year. Reigning champion in the GRC Lites class, Mitchell DeJong did not step up to the Supercars class, but his teammate Sebastian Eriksson, who became second in the GRC Lites championship last year, did step up to the highest class in the GRC and became Joni Wiman's teammate.
