"At the moment they've clearly got it within a very small percentage, or maybe it's the same, as a V8. The shift lights and where the gears are being pulled is all very similar."
The new engine is expected to feature in next year's Supercars Championship on a 'wildcard' basis, as Triple Eight continue to develop it for a full race program across their team's new Holden ZB Commodores in 2019 as part of the new Gen II regulations.
Though Holden have campaigned six-cylinder engines in the Australian Touring Car Championship in the past, including when Peter Brock took his first Bathurst win in 1972, initial fan reaction was mixed. However, those on Mount Panorama have largely praised the new power plant having seen it in action for the first time.
"I'm wrapped and stoked that [fans] have taken it on as positively as what they have," said Murphy. "We've had V8s ... that noise for such a long period of time. It's hard to adjust, but we've got to look at it as a different option potentially down the line.
"It doesn't mean that everybody's going to be running V6 turbos in the future; we could have a complete mix of things. And I suppose that's something that could be exciting."
Supercars, like many other categories across the globe including the World Endurance Championship and Formula 1, faces an era of change and adaption to the ever changing motoring market.
"I'm obviously a big fan [of V8s]; I have been forever. I like the sound, I like the noise, I love what it means. But, we need to accept that there is change around the place and you've got to move with the times I suppose.
"I think everyone should be focused on making sure we provide good racing. We've got teams and drivers here that are equal to the best in the world and we need to maintain and make sure that we continue to keep that rolling on.
"Yes the sound might change a little bit, but I think as long as the racing and the superstars that drive the cars maintain the excitement level ... then a little bit of acceptance on maybe a different engine note is something you've got to look at.
"It's still a high horsepower combustion engine, which is what I love. As long as it's burning fuel, pumping some flames, and going fast, then we should be pretty pleased."
