Porsche has opened up top in free practice for the Fuji 6 Hours, with Mark Webber, Timo Benhard and Brendon Hartley heading the timesheets at the end of FP2.

With Porsche and Audi primed for title battle with just three rounds remaining, Webber, Bernhard and Hartley - winners of the last two races but still ten points behind the Audi of Andre Lotterer, Benoit Treluyer and Marcel Fassler overall - ended up quickest of the day around the Japanese venue after three hours of track action.

The Audi trio of Fassler, Lotterer and Treluyer followed up in second place, with the sister #18 Porsche and #8 Audi following up in third and fourth.
