NASCAR Eyes Evolution of Next Gen Car: Exploring a Shift from Strict Spec to Strategic Differentiation

Charlotte, NC – The NASCAR Cup Series, currently navigating its fourth season with the standardized Next Gen car, is reportedly engaging in discussions about introducing a degree of variability back into its technical regulations. This potential shift comes as drivers and team personnel increasingly voice concerns about the limitations imposed by a highly controlled, spec-based platform, even as statistical data suggests an increase in on-track passing.

The Next Gen car, introduced in 2022 with the primary objectives of reducing costs for teams and promoting closer racing through a single-source supplier model, has achieved significant milestones in streamlining car development and manufacturing. However, a growing sentiment within the garage areas suggests that the very uniformity that was intended to level the playing field may be inadvertently stifling strategic differentiation and the organic emergence of performance disparities.

Chase Elliott, a prominent figure in the Cup Series and the 2020 champion, was an early proponent of this discussion. Prior to the Next Gen car’s debut, Elliott articulated concerns that an overly restrictive rulebook could lead to a homogenization of speeds, making overtakes more challenging, particularly on tracks with limited racing grooves. His perspective, which has been echoed by others in the sport, posits that when cars are too similar, the ability for teams to engineer unique advantages becomes significantly constrained.

"We’ve talked about this before, but for sure, the more we’re the same, the harder it is to be different," Elliott recently shared with Motorsport.com. "Everyone at this level is really good at driving these cars. Most of the tracks we go to, there is a preferred lane, and when the track gets rubbered in over the second half of these races, it becomes really difficult to do something different than the guy ahead of you since he’s in the optimal line."

Elliott further elaborated on the evolution of motorsports engineering, noting that advancements in aerodynamics and car tuning have progressed significantly over the years. "Go back 20 years ago, and the sport was still finding out how some of these knobs and levers worked, and now we have," he stated, implying that the current level of collective knowledge is so high that the standardized car offers fewer opportunities for groundbreaking innovation.

Despite these reservations, Elliott acknowledges the current reality and the emphasis it places on other crucial elements of racecraft. "So now, we’ve never had a bigger emphasis on qualifying and your pit stall, how fast that last pit stop is, and all those things," he said. "It’s for sure a different time in motorsports, regardless. So, in my view, you have to learn to appreciate the challenges that we have today, because I just think they’re probably going to be a little bit different and, and probably going to be different forever."

NASCAR leadership has acknowledged these discussions. In an October appearance on the Dale Jr Download podcast, NASCAR President Steve O’Donnell indicated an openness to revisiting certain aspects of the Next Gen car’s technical specifications.

"We’re always open to changes," O’Donnell stated. "The one piece I really look at, and I think our group does, we have this car and some things contained from a cost standpoint but what does everyone really like? The ability to tweak on the car and find an advantage to do something cool. What’s the next iteration of that? Now that we have the parts and pieces long term, maybe we look at race teams are making some parts again, some things we can open up."

O’Donnell outlined a potential approach where cost caps could be implemented to allow for increased team-driven development. "We give it a cost cap where we can open it up. But we’ve at least stopped the wasteful spending and now we want to get it back to where an engineer can come in and tweak on a car or an OEM can say ‘this is our IP and we want to try something’ from a new technology standpoint. We’re open to tweaking on it. We had the mindset of needing to stop the bleeding so now what can we do to keep making the racing better?"

When asked about the prospect of introducing more variability, both Elliott and fellow Cup Series driver Brad Keselowski expressed a cautious interest, emphasizing the need for specific details. "It’s just hard to speculate because I don’t know what specifically he is talking about," Elliott responded. "Like, super casually, yeah but I just don’t know what he means." Keselowski echoed this sentiment, stating, "It’s hard to provide an answer without knowing what exactly they would want to do."

However, some crew chiefs have shown more immediate enthusiasm for the potential return of greater engineering freedom. Adam Stevens, crew chief for Christopher Bell and the Joe Gibbs Racing No. 20 team, voiced his support for the idea, reminiscing about eras where engineering innovation played a more significant role.

"I mean, that’s interesting and I hadn’t heard that OD said that at all," Stevens commented. "I would certainly be in favor of it. Even if I remove myself from the crew chief chair, and take the 30,000 foot view, when you have the ability to work on the car beyond the shocks, and springs, and set-up parameters, it creates competition, right? Throughout the history of the sport, at least in my time, somebody has a hot hand and someone doesn’t. You can be on the leading edge of the development curve and everyone catches up and you have to get back to work. It creates comers and goers, and fast cars and slow cars, people on the way up and down, with more areas in which to compete."

Stevens admitted that identifying specific areas for deregulation is a complex task. "I would certainly be in favor of it but as far as areas where, I don’t know, but I would love competing in any area of the car with the equipment that I would be allowed to," he said. "Selfishly, that is part of the sport that I enjoyed immensely that is kind of gone. I know a lot of talented engineers, racers and fabricators are the same way. I feel like we’re missing that. If they would sprinkle some of that back in, I would certainly enjoy that."

Chris Gayle, crew chief for Denny Hamlin and the No. 11 team, also expressed a general optimism, suggesting potential areas for consideration. "We need to look at some of our underbody stuff," Gayle proposed. "Do we need to sit on the shocks. There are some areas they could open up that wouldn’t cost anything, that might would create opportunities, but it’s so hard to say right now without having a lot of time to think about it."

Rudy Fugle, crew chief for William Byron and the Hendrick Motorsports No. 24 team, specifically highlighted the current reliance on shock limiters as a restrictive element. "Absolutely, yes, 100 percent in favor of opening some things up," Fugle stated. "There are plenty areas of the car that you could say, ‘whatever you want to do but don’t do this’ and ‘don’t change that’ to make things way more open. Right now, the car and the setup has been developed around the shock limiters, really. That’s how we keep the cars off the track and that’s created the entire setup around that."

Fugle believes that targeted deregulation could re-energize teams and enhance the competitive landscape. "There are some things I think we could do that wouldn’t be very expensive, in my opinion, it would just take some development. It would be running sim and tinkering — more time than anything else. And that would inspire some of the groups at these race teams too. We have some burnout, going through the year, and we are so limited on what we can change, and with just a little but more opening of the rule book, that could get us excited and it would be fun."

Paul Wolfe, crew chief for the Team Penske No. 22 team, while not having heard O’Donnell’s comments prior, also conveyed a desire for increased innovation. "Well, I hadn’t heard about that or considered that it would ever be on the radar to open some things back up so I need to put some more thoughts into it to give you better answer," Wolfe said. "But generally, I enjoy change and I think it’s healthy for competition. When the rule book changes and evolves, it creates opportunity, and creates some separation with teams finding that speed early and then others catching up and surpassing them. I support anything that allows for that kind of competition."

Wolfe concluded by emphasizing the perceived stagnation in the current car generation. "We’ve gone quite a while now with this generation car with things being pretty stagnant. Those of us who have been in the sport a long time enjoy the competition and creativity and I think the racing would definitely benefit from giving teams a chance to make some things happen or find advantages, even if it’s just for a short period of time."

As NASCAR evaluates the long-term trajectory of the Next Gen platform, the ongoing dialogue between the sanctioning body and its competitors suggests a potential evolution aimed at balancing cost control with the fundamental elements of engineering competition that have historically defined stock car racing. The specifics of any potential rule changes remain to be seen, but the conversations indicate a willingness to explore adjustments that could inject greater strategic depth and dynamic racing into the Cup Series.
