In 2015, Team Penske entered the Australian V8 Supercars Championship, having purchased a 51% stake in Dick Johnson Racing in September 2014. The team was known as DJR Team Penske. The team raced a single Ford Falcon FG X in 2015, initially with Marcos Ambrose driving car No. 17 and Scott Pye as a co-driver in the Endurance Cup. Following the Australian Grand Prix support race, Ambrose requested to step aside from driving to let Scott Pye become the main driver from Round 2 at Symmons Plains onwards. Ambrose then became the endurance co-driver in the Endurance Cup.
