The 2015 World RX of Argentina was the final round of the
second season of the
FIA World Rallycross Championship.[1] The event was held at the
Autódromo Municipal Juan Manuel Fangio in
Rosario,
Santa Fe, over one day following the declaration of unsafe track conditions on the first scheduled day of competition. This led to the first World Championship event to be held over only three heats.
Petter Solberg secured his second consecutive title having only needed to advance to the semi-finals to achieve it.
