Down to 1:47.9 in FP2, that's about a second away from the absolute prototype track record set in 2008 in Audi's R10 TDI. 1:46.935 is the time to beat but I have my doubts if they can go that fast in qualifying. No idea how repaved track compares to 2008 conditions but laptimes are impressive already.
