Porsche added to its remarkable sportscar record by securing the Manufacturers' title in the FIA World Endurance Championship during a soggy 6 Hours of Shanghai.
Another one-two finish by the pair of 919 Hybrid machines headed by drivers' points leaders Mark Webber, Brendon Hartley and Timo Bernhard, saw the leviathan Weissach operation seal the title.
In only its second season racing the class-topping 8MJ armed 919s which are considered to be the most technologically advanced competition cars ever made, Porsche is now on the brink of double WEC celebrations.
Webber, Hartley and Bernhard will go into the final round at Bahrain from November 19-21 with a 12-point advantage over their only rivals for the crown, the #7 Audi of Andre Lotterer, Marcel Fassler and Benoit Treluyer.
Armed with a hybrid system which generates energy recovery from both braking from the front axle and the exhaust, the 2-litre four cylinder turbo-charged combustion engine combined with the advanced lithium-ion battery is good for 1000bhp.
