The second session saw the #1 Audi of Marcel Fässler, André Lotterer and Benoît Treluyer setting the fastest time in what was a red flag affected session. They placed first ahead of the two Toyotas, #8 leading #7. Audi #2 with Tom Kristensen, Allan McNish and Loïc Duval placed fourth. The Rebellion Racing Lola rounded out the LMP1 runners in fifth.

Update:
Shortly after the conclusion of the second free practice session the news emerged that the fastest time for Audi #1 was disallowed, due to a pitlane speeding violation, similar to what happened to Toyota at Fuji. Thus the amended finishing order featured a Toyota 1-2 result, with the #8 Toyota TS030 Hybrid ahead of the #7. Audi #1 dropped to third, followed by the fourth placed #2 Audi.
Updated LMP1 second free practice results:
