Matthew Brabham will add another chapter to the famous racing name's legacy after securing a berth at this year's Bathurst 1000.
The 23-year-old is the son of Bathurst and Le Mans 24 Hour champion Geoff and grandson of three-time world Formula One champion Jack.
He will partner Lee Holdsworth at Preston Hire Racing for this season's Supercars' Enduro Cup, which includes the Sandown 500, Bathurst 1000 and Gold Coast 600.
The third-generation driver has had open-wheel racing success in the US, finishing 22nd in the 100th Indianapolis 500 in front of more than 400,000 fans two years ago.
Intent on securing a future in the sport, Brabham has returned to Australia and had immediate success, winning the Class C Bathurst 12 Hour by four laps with Aaron Seton and two-time Bathurst 1000 winner Tony Longhurst at his track debut earlier this month.
Brabham says his family tried everything to keep him away from motorsport, but are now the perfect allies as he eyes a full-time Supercars drive.
"They were trying to put golf gloves, tennis racquets and anything but a steering wheel in my hand," he said.
"It took me pestering them a long while to get me in a go-kart.
"They didn't want me to go into racing, but growing up listening to such cool stories from my grandfather and dad ... I wanted to get into it."
Brabham was flanked by the same car his grandfather drove to victory in the 1964 Australia Grand Prix at Monday's announcement, but said the constant reminders of his family's racing pedigree don't build any extra pressure.
"I just look at my grandfather as my grandfather and dad as dad," he said.
"They're pretty experienced, they understand motorsport so they don't add any extra pressure.
Brabham will continue to race in the Stadium Super Truck Series in Australia and the US this year, while taking part in Friday's Supercars test day at Sydney Motorsport Park.
"It can go anywhere for him; he's very young, he's got a big name and plenty of years in front of him," Holdsworth said.
"He could end up as a full-time driver in V8 Supercars and I'm sure that's something he has in his sights, but there's opportunities overseas for him as well."
