Denny Hamlin stated that NASCAR is facing a “physics problem” with the Next Gen cars, which hampers drivers’ ability to overtake during races.
Delving into the details of the vehicle, passing is crucial. However, when the cars themselves create obstacles and stifle creativity—and even excitement in the race—Hamlin has reached his limit.
The crux of the issue lies in physics, according to Hamlin.
“The major difference between XFINITY and Cup is that in Cup racing, as you get closer to another car, your own car tends to take off,” Hamlin said on Actions Detrimental. “You lose all your downforce. It’s finished. In XFINITY racing, however, as soon as you close in on someone’s rear bumper—as evidenced by what Riley Herbst and others demonstrated—you begin losing rear downforce once you’re near their car.”
“That used to be our approach with the Gen 4 and Gen 5 cars; we could always manage to loosen up the driver ahead of us. Now that isn’t possible because there’s no effective over-body aerodynamics—it’s all about underbody design. You can’t disrupt their spoiler since there’s barely any air acting on it initially. We have a physics dilemma here. I wish they would allow us to devise our own package for that track just once and let us choose what we’re going to use.”
Denny Hamlin addresses NASCAR’s ‘physics problem’
<pHamlin, regarded as one of the most successful drivers currently competing, insists there’s a fundamental physics issue within the sport. What implications does this hold for future events?
No one knows for sure.
“Chris kept mentioning how close we were,” said Hamlin regarding an in-race conversation. “We’re kind of right there. I wasn’t sure if he would need me to pass anyone during that final stage because it simply wasn’t feasible—it really comes down to physics.”
“I think Chase Elliott brought it up during the race: If you could hand me a button for physics help—that would be fantastic! Because if someone figures out how to pass effectively then we’re ready for battle.”
At this juncture, it seems both Hamlin and everyone else find themselves racing against time to unravel these scientific challenges.

Denny Hamlin Highlights NASCAR’s ‘Physics Problem’ Impacting Race Dynamics
Understanding the ‘Physics Problem’
NASCAR racing is as much about speed and strategy as it is about the science behind the sport. Denny Hamlin, a veteran driver and team owner, recently pointed out a significant issue he describes as a “physics problem” affecting race dynamics. This concept revolves around how cars interact with each other on the track, particularly during high-speed racing scenarios.
What is the ‘Physics Problem’?
The ‘physics problem’ refers to the challenges drivers face regarding aerodynamics, car handling, and tire performance while racing in packs. Key factors include:
- Aerodynamic Drag: When cars race closely together, they create a turbulent airflow that can slow down the lead car.
- Weight Transfer: During rapid acceleration or braking, shifting weight can affect tire grip and handling.
- Drafting: While drafting can provide a speed boost, it also complicates car control when entering turns.
The Impact on Race Dynamics
The physics problem has wide-reaching implications for race strategies, car design, and ultimately, the outcome of races. Key impacts include:
Car Design and Engineering
Teams invest heavily in engineering to mitigate these physics-related challenges. For instance, the design of the front splitter, rear spoiler, and overall body shape can influence how well a car cuts through the air. To address the physics problem, teams often focus on:
- Optimizing downforce without increasing drag.
- Implementing advanced suspension systems to improve weight distribution.
- Utilizing tire compounds that enhance grip without sacrificing durability.
Race Strategy Adjustments
Understanding the physics problem allows teams to adapt their race strategies effectively. Key strategies include:
- Pit Stop Timing: Knowing when to pit can create an advantage, especially when taking advantage of drafting opportunities.
- Team Orders: Coordinating with teammates during a race can help maximize aerodynamic benefits.
- Positioning for Passing: Drivers must anticipate the dynamics of airflow to make successful overtakes without compromising speed.
Denny Hamlin’s Perspective
As a prominent figure in NASCAR, Denny Hamlin’s insights on the physics problem shed light on how it shapes competitive racing. He emphasizes that:
- The need for better aerodynamics in new car designs is crucial to minimize the physics problem’s impact.
- Drivers must be educated about these dynamics to make real-time decisions on the track.
- Collaboration between drivers and engineers is vital for ongoing improvements.
First-Hand Experience
Hamlin’s extensive experience on the track allows him to provide unique perspectives. His observations during races have shown that:
- In close racing situations, the smallest changes in speed can lead to significant outcomes.
- Understanding how other drivers react can help in strategizing moves at critical moments.
Case Studies: Races Affected by the Physics Problem
Several notable races in NASCAR history illustrate the impact of the physics problem. Here are a few examples:
| Race | Year | Key Takeaway |
|---|---|---|
| Daytona 500 | 2020 | Last-lap drafting chaos led to multiple lead changes. |
| Talladega Superspeedway | 2019 | Aerodynamic advantage shifted drastically, influencing the finish. |
| Phoenix Raceway | 2021 | Weight transfer issues impacted tire performance in the closing laps. |
Benefits of Addressing the Physics Problem
Tackling the physics problem can lead to several benefits, not just for individual teams but for the sport as a whole:
- Enhanced Safety: Better understanding of aerodynamics can lead to improved car stability and safety during high-speed racing.
- Increased Competition: Leveling the playing field through improved designs can lead to closer races and more exciting finishes.
- Fan Engagement: As races become more competitive, fan interest and engagement can increase, benefiting the overall popularity of NASCAR.
Practical Tips for Teams and Drivers
To better address the physics problem, teams and drivers can implement the following tips:
- Conduct Simulations: Use advanced simulation tools to understand airflow and draft dynamics.
- Data Analysis: Analyze telemetry data to identify trends in car handling during races.
- Continuous Learning: Stay updated with the latest advancements in automotive aerodynamics and tire technology.
Conclusion
Denny Hamlin’s insights into NASCAR’s ‘physics problem’ highlight the significant role that science plays in racing dynamics. By understanding and addressing these challenges, teams can enhance their performance, create more thrilling races, and ensure the safety of the drivers. As NASCAR continues to evolve, the integration of physics into race strategies will remain crucial for success on the track.
