Amid the results from yesterday's chaotic Bathurst 1000, the championship order and PIRTEK Enduro Cup rankings got comprehensively shuffled.
With race polesitter Scott McLaughlin eliminated early with mechanical issues, it appeared that Red Bull Holden Racing Team pilot Jamie Whincup would be able to take the points lead. But then when he too succumbed to mechanical woes, Coulthard became the lead beneficiary.
"I think if you sat me down before Bathurst and said we'd leave here leading the championship, leading the PIRTEK Enduro Cup, we would've taken that with both hands," said Coulthard.
"It's unfortunate for the other guys. We just needed to make the most of our opportunities, pick our battles, and get to the finish line."
The Kiwi now leads the standings on 2431 points; 91 points ahead of Jamie Whincup in second and 97 points ahead of Scott McLaughlin in third. He and co-driver Tony D'Alberto also lead the Enduro Cup points.
