 Even more radical changes to the qualifying criteria, and to the format of the playoffs itself, were announced for the upcoming 2014 Sprint Cup Series.As of 2014, the 10-race playoff format involves 16 drivers chosen primarily on wins during the "regular season"; if fewer than 16 drivers win races during the regular season, the remaining field is filled on the basis of regular season points.These drivers compete against each other while racing in the standard field of 40 cars.
