The Australian V8 Supercar is 400lbs lighter than a Sprint Cup car, but only has 650 horsepower compared to 950 in NASCAR.
Austin, Texas (Tuesday, April 23, 2013): Former NASCAR Sprint Cup Champion Kurt Busch and ex-Australian V8 Supercar Champion James Courtney took part in a unique driver swap at the Circuit of The Americas today - the former title winners swapping cars at the Austin, Texas venue.
The Circuit of The Americas will host the V8 Supercar Championship on May 17-19 with Australia's finest teams and drivers doing battle on US soil for the first time.
In a prelude to the first ever event in North America, Busch (the 2004 NASCAR Sprint Cup Champion) and Courtney (the 2010 Australian V8 Supercar Champion) today drove each other's cars around the Texas venue.
Furniture Row-Racing's Busch had to adapt to sitting on the wrong side of the car, a sequential shift gearbox and a dramatically smaller steering wheel. For Courtney, he also found himself on the other side of the car from what he is used to and having to revert to using a H-pattern gearbox that hasn't been used in V8 Supercars in 2007.
The only similarities between the Chevrolet SS NASCAR and the Holden Commodore V8 Supercar comes from their road-going versions - the same car is sold in both markets in respective left and right hand drive versions.
"It's amazing, there are similarities and differences between the two cars," Busch said.
"Sitting on the right side, shifting a bunch of gears with my left arm, you're not in your comfort zone and it's hard to understand what task of the car is next until you start checking things off your list that you learn the racetrack as well. So there were quite a few things going on. Information overload, to say the least.
"But it definitely makes it interesting to drive both cars on the track at the same time.
"Much more power than what you see in the GT classes in the Grand Am series. And 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."
Holden Racing Team's Courtney and fellow Championship contender Fabian Coulthard (Lockwood Racing) were on hand at the Circuit of The Americas for today's activities as well as last weekend's successful inaugural MotoGP event where they undertook demonstration laps at the venue.
For the vastly experienced Courtney, today's track action was a dramatic twist for the Australian who has driven a wide range of machinery including Formula 1, Le Mans and Japanese Sportscars, Formula 3 and Formula Ford.
"It was pretty wild sitting on the other side of the car and shifting an H-pattern gearbox," Courtney said.
"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. I'm forever grateful that the team gave me this opportunity.
"The steering wheel, it feels like it's massive. But to run side-by-side I was pretty nervous because it's moving around a bit more than what I'm used to.
"But the car was excellent. Changing with an H-patter gearbox is different; it's done almost automatically in the car at home so you never think about it. But another thing that is quite different is the braking performance.
Courtney and Coulthard will return home this week to prepare for the next round of the V8 Supercar championship in Perth, Western Australia on May 3-5.
Teams will then prepare their cars for the first ever US event which will showcase Ford, Holden (GM), Nissan and Mercedes-Benz AMG V8 Supercars doing battle at the Circuit of The Americas.
