Ford will be increasing its involvement in the nascent Global RallyCross Championship for the upcoming 2013 season. The automaker made a big splash at the Chicago Auto Show by bringing in Ken Block, Tanner Foust, and Brian Deegan, three of the biggest GRC stars and all three under contract to Ford teams. Also on hand was the new Ford Fiesta ST GRC car, a vehicle which has been built in partnership with OlsbergsMSE and which is based on the upcoming Fiesta ST production car.
