Button admits that his Le Mans team mate Johnson, a seven-times NASCAR champion who made the bold move to IndyCars in his mid-40s, has been a big inspiration.
“Jimmy has been very useful, not just with this, but with my Garage 56 project. He’s driven stock cars his whole life. So we all know how difficult it is to shift from an open-wheel high downforce car to a stock car and vice versa.
“And I think Jimmy showed that the last couple of years – it’s tough. And I think he did a bloody good job, but it just shows how difficult it is, and how different it is. But he’s been really helpful.
“I said to him when I had this opportunity, ‘What do you think? Should I do it?’ He said, ‘Mate you definitely have to do it, you’ll have a blast.’ I said, ‘I’m in’. If Jimmy thinks it’s gonna be fun, it’s gonna be fun…”
The Garage 56 project is progressing meanwhile, and Button has already done three tests with the car, including one at COTA that should give him a bit of a head start when he returns for the NASCAR race later this month. He expects that the car will capture the imagination of fans at the Le Mans 100th anniversary event.
“It’s got a lot more power, I think it’s got four times more downforce. And the V8 sounds insane”
“They definitely will like what they see,” he says. “It does look like a Cup car with a few winglets on it, but we haven’t put a rear wing on the car because we don’t want it to look different to a Cup car. The diffuser is the same as a Cup car, there’s no difference. So, it does look like a Cup car.
“But I have to say it’s not the same performance, it’s got a lot more power, it’s a lot lighter, I think it’s got four times more downforce. And around a normal track, it’s eight to 10 seconds a lap quicker. So it is faster. But I think in terms of the way it looks, and the way it sounds, Cup cars sound insane. It’s just such a wonderful sound from that V8.
“And I think that’s what’s going to blow everyone away. That’s what I’m most excited about, it’s going to be a fan favourite, definitely, at Le Mans. And it will bring a lot more interest to NASCAR.”
So far things are progressing well: “We did a 24-hour test in Sebring. And we had one issue, but apart from that, everything went very smoothly. They are built very strong. And I was amazed at how reliable the car was over 24 hours. So that’s a big challenge for everyone involved, and to see that the car can do 24 hours with one issue is very impressive.
“And I think it really shows the strength of a Cup car and what these guys are doing. They understand what they need to do to make it reliable for four hours, but I bet they didn’t expect it would last 24!”
