New Zealand driver Brendon Hartley and his Porsche team-mates Mark Webber and Timo Bernhard have won the World Endurance Championship after the 6 Hours of Bahrain race.
It is a first world title for the New Zealander and Australian Webber, who was third in the 2010 Formula One championship for Red Bull.
Hartley's car experienced technical problems during the endurance race but a fifth-place finish was enough to secure the title.
Audi's Andre Lotterer, Marcel Fassler and Benoit Treluyer came second when a win would have given them the crown.
Hartley's Porsche, shared with German Bernhard and Webber, had won the previous four races before the season-ending event in Sakhir.
The sister Porsche car of Neel Jani, Marc Lieb and Romain Dumas won the Bahrain race.
