They're 1 and 2 in the Virgin Australia Supercars Championship right now.
But they're great mates according to Scott McLaughlin after climbing to second with victory on Sunday at Hidden Valley.
“I feel like me and Fabs are working together the best I’ve ever had with a team-mate,” he said.
“I’m really enjoying the battle that we’re having and I think everyone in the team’s really liking it too, the #12 and #17 boys are having a bit of a competition.
Just 10 points separate the Kiwi pair with McLaughlin enjoying a purple patch right now having won four of the last six races.
Since Adelaide he's also outqualified Coulthard in the past 8 of 10 races.
“It’s a really cool dynamic in the team and I’m just excited to just keep pushing within the boundaries."
“We can race hard but fair and no contact. So far I feel like there’s been no issues at all."
Whether or not the bromance continues remains to be seen.
There's also room for another contender to challenge the Shell V-Power team mates.
Jamie Whincup is just six points behind McLaughlin and still in the hunt should Red Bull rediscover their previously dominant form.
But the man in the #17 is confident he's got the tools at his disposal to have a serious crack at a maiden title.
“I just want to be consistent. I feel like if we just keep doing these results, second, third, a couple of wins here and there, we’ll be there or thereabouts at the end of the day.
“Jamie hasn’t won a race yet but he’s right there just waiting to pick up the pieces and Shane (van Gisbergen) will come back.
“The championship is wide open and until we get through the enduros we won’t worry about it until then.”
The battle resumes at the Townsville 400 from July 7-9.
