'Days of Thunder sparked love of NASCAR', says Jenson Button, ahead of Cup and Le Mans races

“For a very long time, I’ve watched NASCAR, a couple of decades,” he says. “Growing up in the UK we had four channels on TV back in the late 80s. And we didn’t get any real sport outside of European sport. So it was actually Days of Thunder that first of all brought me to NASCAR, because it was the first time I got to see any NASCAR.

“I mean, it was a movie. So as an eight-year-old [he was actually 10!], I thought it was insane, I thought it was amazing — worlds away from European motorsport. But that kind of got me in the door of liking NASCAR. And I used to watch it with my old man. It’s so different to what it used to.

“And I think that’s probably what stopped me asking the question whether I’d be able to race in NASCAR, because it’s so different to anything I’ve driven before. And also back then it was more ovals, there weren’t really any street courses.

“So that didn’t excite me so much, because it’s another skill set all together. But now there are more road courses, it’s definitely more enticing.

“I watch the races and I see the new guys coming in that have experience in road course racing. And they don’t find it easy, it’s very difficult. But I think that’s part of the challenge and why I’m excited about it.”

Jim Clark famously sampled NASCAR in the sixties, helped by his Ford links, and a few other well-known F1 names also had a go, Mario Andretti, Dan Gurney, Pedro Rodriguez, Jackie Oliver and Rolf Stommelen among them. However for decades, through the 80s and 90s, there was no crossover at all.

That’s changed in recent years. Juan Pablo Montoya was one of the pioneers, making NASCAR his focus from when he left F1 in 2006 until 2013. More recently we’ve seen the likes of World Champions Kimi Räikkönen and Jacques Villeneuve racing in NASCAR, while Fernando Alonso and Lewis Hamilton have tested cars as PR stunts. There’s an obvious mutual respect between the drivers from two very different disciplines.

“I’ve looked at NASCAR before as being super cool to watch on the ovals, short course/long course ovals,” says Button. “And it’s very cool, but I can’t really relate to it, because it’s so different. I think because we have more road courses now, and they look a handful, but the racing is amazing. It’s proper cool to watch.

Focusing on the road courses has ensured that Button will be at home in a familiar environment in Austin and Indianapolis He’ll be on a level footing with everyone else at the new Chicago street venue.

“The three circuits that we’ve chosen work out really well, because COTA I’ve driven at before, so I’m just learning the car, because you don’t actually get any practice before the race weekend. Now you get 50 minutes at the race weekend, I thought it was 15! That’s a bit better.

“And then the second one is Chicago, no one’s driven in Chicago on the street course, or driven one of these around a street course. I mean, it sounds nuts, but it’s the same for all of us. And then Indy, it’s different to the F1 track I drove there, but it has some of the same corners.”

Sonoma clashes with Le Mans, and he’s missing the other road course on the 2023 schedule – Watkins Glen – because it falls a week after the Indy event, and with only one chassis available the team won’t be able to do both.

Button is already getting comfortable in the car, even if there’s no opportunity to actually test.

“I’ve spent a lot of time with the team, getting to grips with the feeling of the car in terms of where I’m sat. It’s such an important thing for me, I can’t be set up straight with a steering wheel here on my lap, I need to be set back a bit more like a single-seater.

“And we found a position that works for me. And if I have that, I’ll have a lot more feeling through the car and be able to get to grips with it quicker.

“I have simulator time set up next week, which is great. And I’ve already done my seat fit so I’m comfortable in the car. So yeah, it’s simulator time, spending time with the team, getting an understanding of brake traces, throttle traces, lines, and all of the data that they have, because there is a lot of data.

“Obviously less than F1, because they’re not allowed to have more than they have. But there’s still a lot of data there for me to look at and learn from before I step out onto the track in COTA.”

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!”
