“It was pretty wild sitting on the other side of the car and shifting an H-pattern gearbox,” Courtney said. "Changing with an H-pattern gearbox is different; it's done almost automatically in the car at home so you never think about it.
"Another thing that is quite different is the braking performance," he continued. "The car was bigger and heavier. It has so much power. It's really quite an experience. It was also quite cool to see blow past the V8 car on the straight. It was really good.
Adding that the oversize steering wheel favoured by NASCAR "feels like it's massive," Courtney said that he was still far from confident handling the stock car at the end of the day's track opportunity: "To run side-by-side I was pretty nervous because it's moving around a bit more than what I'm used to, " he said. "But the car was excellent ... It's built for Speedways, not really road courses. It's a very different machine."
For his part, Busch was envious of what he'd seen of the V8 series' close quarters running: "The ability, though, for what I see on TV, for these guys to run side-by-side, nose-to-tail, is the control of the cars, the balance they have makes it a treat to drive."
Another former V8 Supercar champion form Australia, Marcos Ambrose, currently competes full time in the NASCAR Sprint Cup Series for Richard Petty Motorsports, and has two poles and two wins to his credit as well as a further four wins in the second-tier Nationwide Series competition.
The swap came a day after multiple MotoGP champion Valentino Rossi had a similar experience, trading his usual Yamaha motorbike for a much heavier NASCAR stock car at Charlotte Motor Speedway on Monday when he was given the opportunity to drive Kyle Busch's #18 Cup car.
"Exciting, high speed and a great feeling in the corner," Rossi said afterwards, adding that many of his friends were NASCAR fans. "You are glued on the racetrack. It was great, I enjoyed it a lot. I love driving the race car, and I always have, so it was exciting to drive a NASCAR."
