Kiwi driver Scott McLaughlin crossed the line 1.1 seconds ahead of Craig Lowndes’ Red Bull Holden Commodore, with Michael Caruso’s Nissan Altima finishing third.
The non-championship race victory comes two weeks after the S60 Polestar racer finished second in Race Two at the season-opening Clipsal 500 in Adelaide.
McLaughlin said he expects a degree of backlash from the fans, as the Volvo team continue to develop their race package.
"There is always going to be haters but bring it on," McLaughlin said.
"I am driving the thing as hard as I can and that's what happens; we are going good. There's always going to be doubters.”
Holden Racing Team drivers Garth Tander and James Courtney finished fourth and eight respectively, while Fabian Coultard rounded-out the top five for Lockwood Racing.
All of V8 Supercar racing’s five manufacturers were represented in the top ten for Race Four.
Fellow Kiwi Shane van Gisbergen dominated the race weekend, winning the first three races before a broken roll bar saw him finish 14th in the fourth race.
