The three-time Supercars champion will depart the Aussie series at the end of the current season as he looks to build a new career in NASCAR.
He has already made a winning start to stock car racing with victory on the streets of Chicago, and will make a first oval start in the Truck Series this Friday night before a second Cup Series start on Sunday.
Speaking ahead of those next two outings, van Gisbergen opened up on the differences in racing culture between NASCAR and Supercars.
He said the Chicago weekend reminded him of how fun and well-natured the US paddocks are, something he feels is lacking in Supercars at the moment.
“After qualifying in Chicago, we were talking that night," he said.
"Dad was there and stuff... and just how fun the event was, the atmosphere, the cars in the paddock just under tents, accessible to everyone, you can see everyone’s stuff. It’s a whole different world.
"I remember doing the Rolex 24 a few years ago and you just forget how much fun the race culture is in America. It's intense and the switch flicks when it's time to go and get serious. But everyone’s here racing for the right reasons and enjoying it.
