Brexton Busch has high-speed driving in his DNA

AVONDALE, Ariz. – It’s in the genes—and it’s in the machines.

Kyle Busch’s son Brexton is two months shy of his third birthday, and he’s already showing a precocious need for speed.

With the Monster Energy NASCAR Cup Series visiting ISM Raceway in Arizona for Sunday’s TicketGuardian 500 (3:30 p.m. ET on FOX, MRN and SiriusXM), Busch had a chance to take Brexton four-wheeling in the desert sand dunes.

“Last year he went out with me a little bit,” Busch said on Friday. “We didn’t go too far or too hard because, obviously, with him being that small, they’re not fully developed yet. You try to keep it light on the ‘G’ loads, with banging his neck around and things like that.

“This time around we went for a longer dune ride, but we still tried to keep it to his pace. There were times he picked up his hands and was air-driving like holding the steering wheel. When we were going down, he was turning and going up, and he was turning. And then he fell asleep for a little while. He’s obviously pretty chill and gotten the hang of it pretty quick.”

As a race car driver and car owner, the 2015 champion also makes sure Brexton has the best equipment in the vehicles he drives at home.

“He always kind of likes speed,” Busch said. “His Lightning McQueen cars that he has are souped up. They’re not standard speed at all. He likes to go a little faster than his friends. That’s always pretty fun to watch and see.”
