The 20-year-old talent has become a benchmark for the burgeoning Trans Am scene in Australia over the past few years.
Last weekend he claimed his second consecutive Trans Am national title, winning the final round on penalties at Sandown with teammate Gary Rogers Motorsport Owen Kelly.
But his impressive resume is currently lacking in experience in the Supercars system.
He attempted to make his Bathurst 1000 debut in 2020 with GRM, only for Motorsport Australia for refusing to waive the Superlicence, while financial constraints prevented Herne from jumping to Super2.
According to Hearn, unlikely to change next year, his plans are currently to continue working as a mechanic at GRM while he shoots for a third Trans Am title.
But that doesn’t mean he has given up on his dream of Supercars, Hearn is hoping to use Trans Am as an alternative track to Class One in Australia.
This is despite Trans Am’s poor representation on the Superlicence points table, the winner receiving only seven of the 13 required points.
In comparison, the Super3 winner earns 10 points as does the TCR Australia winner and even the now-expired Formula 4 Australian Championship.
The Super2 winner earns 12 points with the S5000 and Carrera Cup champions.
“I am very happy with the GRM, they have given me a lifeline with the race,” Hearn told the Castrol Motorsport News Podcast.
“In 2020, I was at a crossroads where I thought, should I keep racing bitumen and earn all that money or am I going to go racing on the highway where I can race longer?
“It was only our first year [GRM]And, yes, I’ve been in Trans Am for a long time, but I think it will be the same next year. I’m going to do Trans Am and try to do as much of the S5000 as possible.
“For me going forward, I don’t have the budget to go to Super2, so either I give up my winning lottery ticket, or I need to get [Shane van Gisbergen] Write driver in Trans Am so I can compare myself to the big names.
“I think he’s gone far enough that he’s respected as a path. I’m the one who has to kind of break the water for everyone to show that this path can be done.”
Hearn almost had a chance to rate himself against Van Giesbergen earlier this year, only for Triple Eight to block the Kiwi’s planned Trans Am start at the Queensland Racecourse.
Brody Kostikki ended up grabbing Van Gisbergen’s seat, and the Erebus driver was up front but couldn’t take the win.
According to Herne, having drivers like that makes Trans Am an important cameo as he looks to convince spectators that he is good enough to race in Supercars.
“At the end of the day, all supercar drivers are the fittest, they are the best drivers in the country,” he said.
“But being in Trans Am, we know the cars from the inside out. The talent at the front of the field is as deep as any other class.
“He showed up in QR when Brodie came in and was up front, which you’d expect, but he didn’t wipe the floor with us.
“It would be nice if more supercar drivers would come, as a reference for the crowd. Inside me I know where to sit, but for any of the folks looking it would be nice to have a reference to some of the big names. If that’s the case. Entered SVG, it would be interesting.” Interesting to know where we sit.”
