2013A NASA RallyCross Challenge Season

The 2013A NASA RallyCross Challenge Season was the fourth season of the NASA RallyCross Challenge. Dylan Livengood and Revolution Racing will return as the defending Drivers and Constructors Champions. The season started on 13 January 2013 and ended prematurely on 27 January, due to a drop in car count because of a cheating controversy centered around Xander Clements. The series then came under pressure from a lawsuit stemming from this incident. Due to this the money awarded to the winner of The Drivers, Constructors, and Manufacturers Championships were withheld by the series.
