Porsche set up a fitting farewell for Webber, who now becomes an international ambassador for the German marque, by putting him behind the wheel for the final stint.

The #2 919 Porsche went into the event knowing it had to finish fifth or better to guarantee the drivers’ title, but things came unstuck early when a collision with a slower car punctured the left rear tyre and badly damaged the surrounding bodywork, forcing it into the pits.

Despite the misfortune, the car went on to finish sixth and that was enough to grab Porsche a second consecutive Drivers’ championship and bookend their Manufacturers’ title which they clinched in China two weeks ago.

“It has been a fantastic team effort,” said Lieb of the driver’s title.

“It has been up and down, but the reliability has been the key with the hard work in the garage.”

The win was another milestone for Australian engineer Jeromy Moore, who helped Webber’s team to the driver’s championship last year and the #2 Porsche to a Le Mans 24-hour victory in June.

Moore, who learnt his craft through more 10 years with Triple Eight Race Engineering’s V8 Supercar team in Brisbane, also played a valuable role in helping Porsche to their second consecutive Manufacturers’ title.x

The #6 Toyota of Mike Conway, Stephane Sarrazin and Kamui Kobayashi needed to win the race to give themselves a shot at the drivers’ title, but they were never in the hunt and came in fifth.
