The WRT Audi squad took a 1-2 victory in the main race at the Nogaro FIA GT Series event on a day that the Belgian team gained revenge over Sebastien Loeb Racing.
WRT Audi R8 LMS ultra initially crossed the line in the top three positions, only for the winners on the road, Rene Rast and Nikolaus Mayr-Melnhof, to receive a 30sec penalty for a pitlane infraction during the mandatory mid-race pit stops.
The penalty, received because the Audi's engine was not switched off during the pit stop, promoted the second-place WRT Audi driven by Frank Stippler and Edward Sandstrom and demoted Rast and Mayr-Melnhof to eighth overall and second in the Pro-Am class.
WRT's domination of the results followed a penalty for McLaren MP12-4C driven by Sebastien Loeb and Alvaro Parente.
Mayr-Melnhof had trailed Loeb through the opening stint without the R8 LMS ultra dropping much more than a second off the lead. The Austrian closed the gap to half a second before the pit stops and then a faster turnaround in the pits allowed Rast to just get out of the pits before Alvaro Parente, who had taken over from Loeb one lap before, came past.
Rast held on for a lap before he ran slightly wide into Turn 4 and misjudged move from Parente resulted in the McLaren tipping the Audi into a spin. The Audi dropped 3.5sec off the lead, but Rast needed just seven laps to chase down that deficit and was looking for a way past when the McLaren was called into the pits for a drive-through penalty.
The penalty was not for Parente's misdemeanor but for a pitlane infraction by Loeb: he had loosened and then undone his belts before stationary during is pit stop. That allowed Rast to cross the line 11 seconds clear of Sandstrom.
Stippler and Sandstrom came through from the back of the grid after retiring from the Qualifying Race when a fuse blew and prevented the car from re-starting.
Stippler made up ground early in the race and then another quick pit stop by Vincent Vosse's WRT squad propelled Sandstrom into fourth place. The Swede homed in on the Charouz Gravity Mercedes SLS AMG driven by Alon Day, who shared the car with Maximilian Buhk, but was unable to find a way past until he pulled off an opportunistic move into Turn 9 with 12 minutes to go.
The third WRT Audi, shared by Stephane Ortelli and Laurens Vanthoor, sneaked into third place on the road after Vanthhor passed two cars on the penultimate lap.
Parente dropped to fifth as the result of his penalty and then lost out to Vanthoor.
