New Zealander Scott McLaughlin won the Sunday race at the Gold Coast 600 but title rival Jamie Whincup took control of the Supercars Championship.
McLaughlin and co-driver Alex Premat stormed through the field after qualifying 13th to claim a vital win as the title race heated up in dry conditions on the holiday strip.
The Shell V-Power Ford driver opted to under-cut Whincup at the final pit stop and the move proved crucial as the Red Bull Holden came out just behind the Kiwi after his stop.
McLaughlin held his nerve in the closing stages and his team timed the fuel conservation to perfection to record the win and close the gap to the lead of the championship. But Whincup made the biggest move, leaping over Fabian Coulthard to take a 17 lead in the championship.
Shane van Gisbergen finished completed the podium.
