Since the introduction of the Next-Gen cars in the difference in the cars and the racing style it demands in the first and second tiers of NASCAR has changed a lot. The cars were introduced with the primary objective of reducing the operations cost and parity, hence aerodynamics was given the priority.

This caused this massive change in how the cars would act especially during duals in the top-tier, the Cup series compared to the Xfinity Series, where the old generation cars are used. Lats week, Joe Gibbs Racing’s veteran driver and 23XI Racing co-owner Denny Hamlin explained the big difference while racing these machineries.

He pointed out the biggest difference is the loosing of all the down forces when a car closes down on the leader in the Cup series. On the Xfinity side, the leading car is forced to take evasive maneuvers since they would use the rear downforce if they were closed down. This used to happen in the Cup in the past, but now it’s nowhere to be seen.

That is the big difference between XFINITY and Cup, is that Cup, the closer you get to them, your car takes off. You lose all downforce. It’s done. The closer you get to the car in front of you in XFINITY, and what we saw Riley Herbst and many others do is that as soon as you get close to the rear of the car, they start losing rear downforce, and then they get off the bottom and they shuck them.

Denny Hamlin has a way to solve this issue

The veteran driver pointed out because of aero dynamic issue the passing is really tough compared to the past. But he has an idea to find a solution, as he wants NASCAR to let the teams come up with their own ideas for one race and decide seeing how this experiment turns out.

Now you can’t do that because they are not making any over-body aerodynamics, and it’s all under body. So, you’re not able to take air off their spoiler, because there’s not hardly any air going on the spoiler in the first place....I wish they would just let us come up with our own package for that track just one time and let us decide what we’re gonna run.

The aero-issue being a big hurdle to pass, has been a huge talking point in the racing community since the start of the Next-Gen era. It would be interesting to how NASCAR would fix this problem and if they would explore Hamlin’s ideas.
