Nathan Nicholson is in for a busy weekend on the Streets of St. Petersburg.

The 19-year-old continues his Mazda MX-5 Cup duties with Advanced Autosports at the track for two rounds. However, Nicholson will also get his first of three opportunities to step behind the wheel of a NASCAR Truck this season with Freedom Racing Enterprises, beginning with the series’ first-ever street event at St. Pete.

“The whole stock car thing is obviously very new to me and kind of a curveball in my career, in a great way” Nicholson says in an exclusive interview with GT REPORT. “I’m very excited to have the opportunity. The conversation started with my main sponsor, Whelen, and obviously they’ve been involved in stock car racing for a long time — on the sports car side too. The conversation actually started around this race with the Trucks coming here. I was like, ‘Oh, that would be something cool to do.’ It’d be the next step, and I know the track. I’ve done really well there, and I’m going to be there anyway. The talks started to become more and more serious, and then we decided, you know, let’s do it. Let’s see what we can do and get a handful of races together. So not only this race, but also Watkins Glen and San Diego. I’m looking forward to those, so it’s going to be a cool experience.”

For most drivers in the NASCAR Craftsman Truck Series, street racing is not a trait that has been mastered.

As for Nicholson, the MX-5 Cup standout brings a strong understanding of street racing — most notably at St. Pete — that gives him the upper hand over some of his competition.

“Yeah, I think street course racing is a little bit of a different animal, right? You have a lot of predetermined expectations when you go to a normal track — Mid-Ohio, you know, those other tracks — but with street course racing, every year it’s a little different. The thing that I think breeds the most success at a street course is being able to adapt. The track conditions are changing constantly. You go out for first practice, it’s dusty, it’s dirty, and you have multiple different rubber compounds being laid down. So that ability to adapt — on the car side, helping with setup and giving that feedback, but also as a driver going into every lap with the mindset of, ‘All right, I know this works, let’s try something else,’ or, ‘I had a little bit of understeer that time, how do I need to correct that?’ — is important.”

Nicholson’s adaptability may prove to be one of his greatest strengths as he transitions into the heavier, more powerful Truck.

The jump from a Mazda MX-5 Cup car to a NASCAR Truck is no small adjustment. With roughly 500 more horsepower and nearly 1,200 additional pounds compared to his MX-5 machine, Nicholson knows the learning curve will be steep — especially with limited track time.

“There’s a big difference in power and weight,” Nicholson said. “So being able to keep track of my notes and build confidence throughout the weekend is going to be huge. On a street course, especially making your debut, you can’t afford to beat yourself up. If you hit the wall late in practice, you’re not going to want to drive it in as deep for qualifying. So building that confidence step by step is really important.”

Fortunately for the 19-year-old, the weekend format gives him valuable seat time before qualifying — something not always guaranteed in the NASCAR Craftsman Truck Series. For a rookie making his first start, those extra laps could make all the difference.

“I think practice is going to be crucial for us,” Nicholson explained. “If we went straight into qualifying, there’s almost no way I could put a flyer down. Every minute on track, every lap, I’m going to learn something. It’s about keeping everything together and giving the team as much feedback as I can so we can build the Truck around me.”

Beyond the personal milestone, Nicholson is also stepping into a historic moment for the series. As mentioned, the event marks the first street race in Truck Series history, drawing attention from across the motorsports landscape and bringing together competitors from multiple disciplines.

For Nicholson, the significance runs even deeper.

“It’s historic in a different way for me — it’s my debut,” he said. “I’ve raced this track before, so it may not feel historic in that sense, but making my Truck debut here makes it really special.”

While the Truck debut adds excitement to the weekend, Nicholson’s primary focus remains his championship pursuit in the Mazda MX-5 Cup. After finishing third in the standings last season, he returned to St. Petersburg confident in both his pace and his team.

“Last year here we were super strong,” Nicholson said. “I think we feel even more confident about where our cars are going this weekend. If we keep building that throughout the year, it’s going to be a good season.”

Balancing two competitive series in the same weekend is no easy task, but Nicholson views the opportunity as a chance to showcase both his versatility and the depth of talent within the MX-5 Cup paddock. If his adaptability on street circuits translates the way he expects, St. Petersburg could mark the beginning of an exciting new chapter in his young career.
