World Challenge Cup

World Challenge Cup is a North American-based stock car series which debuted in 2015. The original format consisted of two divisions, one for oval tracks and one for road and street courses. The top drivers from each division met in a two race playoff to determine the champion. The inaugural season championship was won by Frenchwoman Natalie Balandier. The format returned to a traditional calendar for the 2016 season, in which Patrick O'Hannagan won the championship driving for his own team.
