2013B NASA RallyCross Challenge Season

The 2013B NASA RallyCross Challenge Season will be the fifth season for the NASA RallyCross Challenge presented by Royal Purple. After the long hiatus due to lack of entries, Dylan Livengood, Revolution Racing, and Mitsubishi return as the defending Drivers, Constructors, and Manufacturers Champions.

Schedule Changes

 * After noise complaints and poor infrastructure, the Gifhorn event was removed after two seasons. Bent Twig was put in its place.
 * NASA held a vote as to which Proving Grounds track would remain on the schedule, and North was removed.
 * In light of the North Proving Grounds being removed, the long time NASA RallyCross test track, Birmingham Rally Stadium, was granted the 8th and final round on the calendar.

Round 1 - Round of Croft
The first round of the NASA RallyCross Challenge took place, as the four seasons before it, on the Croft Circuit in England. 10 cars competed in the final race. On pole was newcomer Tanner Smith, for ATN AutoSport. On the run down to the first corner, he was alongside Josh Mertz and Mertz had the edge into T1 - until he cut across Smith's nose prematurely and sent himself into the sandtrap. The race was the typical Croft event, a clean, frantic race filled with strategy. Smith held the lead, as Mertz rallied back from 10th (and last) place to get within a carlength of winning the event, thanks to Smith nearly crashing in the Gymkhana section of the course. Smith became the third driver to win in his first start, joining the likes of Elliot Porterfield and David Krikorian. The curse that affected Mertz since 2012A was over, as he finally repeated his second place finish from 2012A. Rounding out the podium was another newcomer, Luke Fleming, with his new Works team, Carolina Motorsports A Class. Defending champion Dylan Livengood had an engine failure on lap two exiting the pitlane, while his teammate Chris Wetz crashed from the transfer spot in the LCQ and Mertz's teammate Cody Erdmann was competing at Slinger Speedway in Wisconsin, which left Mertz in the lone Citroën for the event.
