Pirelli World Challenge is a North American auto racing series that is managed by WC Vision and sanctioned by the United States Auto Club (USAC). The World Challenge series was born in 1990, and celebrated its 25th anniversary season in 2014. The series consists of seven driver classifications and six classes of vehicles: Grand Touring (GT), GT Cup (new for 2015 – for Porsche 991 Cup cars), GTS, Touring Car (TC), “Touring Car B-spec” (TCB) since 2012, and “Touring Car A” (TCA), new in 2014. In 2014, a new GTA driver classification was established for professional drivers that do not make their living primarily from racing.
