Toyota claimed a second FIA World Endurance Championship victory in five attempts in a thrilling battle with Audi at Fuji.
After six hours of racing, Alex Wurz, Nicolas Lapierre and Kazuki Nakajima took the win aboard their TS030 HYBRID by just 11 seconds from the Audi R18 e-tron quattro driven by Andre Lotterer, Benoit Treluyer and Marcel Fassler.
Third place went to the second Audi shared by Allan McNish and Tom Kristensen. The Toyota and the second-place Audi looked evenly matched until early in the fourth hour when Treluyer tangled with the GTE class Aston Martin of Stefan Mucke.
The nose of the R18 needed replacing as a result of the clash, but the car lost little time because the safety car had been deployed while debris from the collision was cleared up
Treluyer was subsequently penalised for his role in the incident, the stop and go dropping the car nearly 50s behind the Toyota. Audi then gambled in the final hour in the knowledge that the Toyota would need to make a splash-and-dash for fuel in the closing stages.
Audi had single stinted its tyres throughout the race, but chose not to replace Lotterer's Michelins at the car's final stop. But Nakajima was able to build enough of a gap to make the splash and still emerge with five seconds in hand.
Nakajima said: "I was getting the message from my engineer that I had to make a 40s gap so we could make the splash. I was pushing like hell and Andre was giving me a hard time, but fortunately we just made it."
The Anglo-Swiss Rebellion Racing squad sealed the Privateer teams' trophy with fourth place for Neel Jani and Nicolas Prost aboard its lead Lola-Toyota B12/60.
The pair were dominant in the unofficial privateers class, finishing one lap up on the JRM HPD ARX-03a shared by Peter Dumbreck, David Brabham and Karun Chandhok.
ADR-Delta drivers John Martin, Tor Graves and Shinji Nakano took LMP2 honours in their ORECA-Nissan 03, but it was not enough to stop the Starworks squad from taking the LMP2 teams' title.
Its HPD ARX-03b finished second in the hands of Stephane Sarrazin, Enzo Potolicchio and Ryan Dalziel.
Porsche was dominant in the GTE Pro class. The Felbermayr-Proton Porsche 911 GT3-RSR led all but the first hour in the hands of Marc Lieb and Richard Lietz.
