Ford's Craig Lowndes made it two from two at Winton Raceway with victory in race six in the Australian V8 Supercars series.
With fellow Ford driver Jamie Whincup having taken out the opening four races of the season to have a perfect record heading into the weekend, Lowndes won race five on Saturday before backing up with victory yesterday.
Mark Winterbottom, also driving a Ford, finished second yesterday with Holden's Garth Tander third.
Whincup finished in 13th position, but still holds a comfortable 114-point lead in the overall championship race.
The New Zealander Shane van Gisbergen is 8th in the Championship.
