Brought back to the pack by safety cars, Lowndes found himself on the outside of Winterbottom and ended up in the gravel. During the race split, Lowndes said he thought they'd be able to race two abreast but Winterbottom was thinking of the championship.
"You don't want damage but at the same time you don't want to let him win ... you're not gonna back off," Winterbottom said.
The biggest beneficiary was Tander, who skated through to the front, leaving Winterbottom in fourth and Lowndes back in 15th. While Tander didn't look back, Lowndes could only finish in eighth, while Winterbottom was fifth.
Earlier, a nudge from Shane van Gisbergen all but ended Ford's Will Davison's championship hopes. Davison was turned around by Van Gisbergen, labelled an "idiot" by Ford Performance Racing team boss Tim Edwards.
Whincup won out, slinking inside the two to climb to sixth. After the race restarted, Frenchman Alex Premat found himself careering through the gravel and crashing into the driver's side of James Courtney's Holden. Such was the damage, Premat had to help a shaken Courtney out from the passenger side. Courtney was later cleared of serious injury.
Heading into today's two races, Whincup leads the championship on 2623 points, 14 clear of Lowndes, with Winterbottom on 2535.
Tander was happy to get a boost from the feisty duel between Lowndes and Winterbottom: "The seas parted and I thought thank you very much, I'll take that," he said."It was quite uninteresting for me which is how you like it."
Coulthard agreed that the clash of the veterans was pivotal: "We all benefited from the Lowndes-Winterbottom incident. It was a pretty action-packed race considering no points were on offer for the first [half]." AAP
