The 2026 NASCAR Cup Sequence season begins now in a fashion of talking.
There might be two days of tire testing on Wednesday and Thursday for Goodyear to proceed refining its tire mixtures for the high-speed half-mile following drastic racing product swings that vary from conventional racing to excessive tire put on.
The swing is essentially believed to be a byproduct of temperatures, with cooler climate discouraging the rubber marrying to the monitor floor and creating the spring 2024 and fall 2025 races the place a set might solely final 30-50 laps when managed appropriately.
Whereas these races have been largely well-received for creating pace differential, and much more contact, the overall consensus is that there’s in all probability a center floor someplace that isn’t as depending on climate circumstances.
That’s what NASCAR and Goodyear hope to determine over the following two days.
“Competitors officers indicated that one of many take a look at’s goals is to find out a tire setup that promotes fall-off and an emphasis on tire administration, however with out the extreme put on from the Cup Sequence’ most up-to-date race on Sept. 13. One other prime aim is to zero in on a setup that’s extra temperature impartial, with tires that react the identical no matter any swings in temps.”
Conducting the checks are the next drivers and groups:
– No. 23 23XI Racing Toyota; driver Bubba Wallace– No. 48 Hendrick Motorsports Chevrolet; driver Alex Bowman– No. 60 RFK Racing Ford; driver Ryan Preece
This take a look at may even symbolize the primary time the brief monitor package deal has been outfitted with the 750 horsepower tapered spacer, one of many new guidelines for the NextGen automotive subsequent 12 months, up from its present 670 HP goal.
After the Bristol take a look at, NASCAR and Goodyear may even conduct a take a look at of some sort at North Wilkesboro, the place the Sanctioning Physique may even think about making technical adjustments to the automotive to proceed enhancing the brief monitor racing product.
When this automotive first debuted in 2022, it significantly improved racing on the intermediate tracks, however on the expense of flat brief tracks and highway programs, wherever that had only one line, because of how aero delicate the trailing automotive is.
NASCAR president Steve O’Donnell stated final month that there’s a willingness to attempt to take an extra swing at making an attempt some issues along with the horsepower enhance.
“I believe what you’ll see us do is, we received the drivers, with the counsel from Christopher Bell and others, Joey Logano, speaking about, ‘Hey! Let’s attempt a few of these issues.’ Working with 3 of the OEM producers and crew chiefs or Heads of Competitors. Placing some concepts collectively, going and making an attempt it at North Wilkesboro and see what occurs.”
Bell, for his half, says the Cup Sequence automobiles have to react nearer to the Xfinity Sequence automobiles.
“I believe they should get the Cup aero map to match the Xfinity Sequence automobiles,” Bell informed Motorsport.com final weekend at Phoenix Raceway. “That may be the most effective case state of affairs, to get the Cup automobiles to react just like the Xfinity automobiles.
“I used to be an enormous advocate of going again to narrower tires, however after all of the work Goodyear has put on this 12 months, the automobiles are sliding round lots now. We go to highway programs and brief tracks, and I can promise you, it’s slippery. At Martinsville, and the Charlotte Street Course, we’re sliding the automotive round lots and are overpowered with the present horsepower.
“I don’t know if it’s aero or mechanical, however I believe it’s aero as a result of we drive the automotive in yaw just like the Xfinity automobiles can and I believe that’s an enormous a part of the attention take a look at — the best way the Xfinity guys seem like they’re hustling the automobiles. Cup automobiles, though we’re near uncontrolled, it doesn’t seem like it on TV. I might like to get us nearer to the Xfinity automotive.”
The Xfinity Automotive is nostril down and tail up, however the Cup automotive makes its downforce from the rear with the assistance of the diffuser so it’s tail down and nostril up.
Bell agrees that’s the largest downside, so how can we repair that?
“I don’t know,” he stated with fun. “We have to discover a method to optimize with that too. Like, NASCAR can’t inform us ‘drop the nostril and lift the tail’ as a result of that’s not how this automotive is perfect. We’ll at all times evolve again to nostril up and tail down perspective as a result of that’s how the automotive was designed.
“It’s worse in site visitors. Because of this we are able to’t get the automotive in entrance of us unfastened. This hurts passing. We have to optimize the automotive with the nostril down and the tail up, and no matter will get us there, that’s what we have to do.”
Along with the tires and aerodynamics, NASCAR may even be testing the brand new Electrical Management Unit and Information Logger for subsequent season – the McLaren TAG-510.
Brad Keselowski couldn’t reply what he desires NASCAR to take a look at with out understanding what they have been open to when requested.
“It’s important to be extra particular for me to have a powerful opinion however I do know the ECU is an enormous a part of that take a look at and getting that proper,” Keselowski stated. “There are a number of issues that these checks might be vital for.”
Dale Earnhardt Jr. has advocated striping the NextGen down fully for brief monitor races.

So how do Cup Sequence crew chiefs plan on attending to the place Bell advised? Briefly, crew chiefs like Bell’s shot caller, Adam Stevens, doesn’t actually know.
“I believe everybody has a deal with on what they need to occur however I don’t suppose anyone has a deal with on what it’s going to take, aerodynamically to make that occur,” Stevens stated. “I would definitely put myself in that class. All of us need the trailing automotive to not be at such a drawback to the main automotive. The best way to make that occur, I’ve not put any time or research into that. I can let you know the those that have taken the time to over time, haven’t had a lot success anyway so I can’t let you know what widget we have to attempt both. If anybody is aware of what that widget is, it isn’t me.”
Rudy Fugle, who serves in that position for William Byron, worries that it could be an costly endeavor to even strip the automotive down.
“My opinion on the aero aspect of it’s fairly complicated,” Fugle stated. “With the best way the underbody and the best way the splitter is and the best way the air flows to the louvers, I believe it could be fairly costly to do some of these items. I haven’t heard of any of their plans to be sincere with you … however there are positively some issues that I believe might assist however they’re fairly large-scale issues for my part.
“It must be a redesign of some issues. There are some smarter aerodynamicists on the market than me. I am not one in any respect, so positively smarter than me. Perhaps they’re getting someplace that I do not learn about.”
Chris Gayle stated he desires to get the automobiles off the shocks and have a look at eradicating elements of the sealed underbody.
With all of that stated, everybody is worked up for a minimum of transferring the product ahead, even incrementally with the horsepower enhance. Paul Wolfe, who serves as crew chief for Joey Logano, stated it’s not going to be an enormous distinction however pairing the horsepower with extra positive aspects from Goodyear, and perhaps an aero tweak right here or there, all begin to add up.
That has actually been the case from the place this automotive began in 2022 to 2025.
“The horsepower factor has been on the radar for some time,” Wolfe stated. “I’m excited for the path. That’s good. I’m not conscious of any of the aero stuff that’s been talked about. We’re already on two completely different packages relating to mile and a half versus brief monitor. We’ve run each packages on brief tracks.
“It’s laborious to say something has been an enormous extra mover on the aero aspect however with all this being stated, we have to needless to say not one change goes to be large, it’s about stacking little adjustments right here and there to make the racing higher. I noticed the place some guys stated ‘weren’t going to see something out of the 750’ however is it going to be night time and day, no, however relating to managing and utilizing your tires, these issues, including horsepower isn’t going to make it worse. It’s going to make the wear and tear worse, which is the place we’re making an attempt to go.”
Wolfe stated ‘we try to stack a bunch of little issues’ to make the leisure will increase, which is not any completely different than what groups do in looking for pace will increase.
“I’m excited to see the 750 package deal and I don’t suppose it’s going to be worse, and it ought to directionally make issues higher,” Wolfe stated. “We’ve completed some good issues with tires this 12 months. Goodyear has pushed the boundary there. We’ve seen good outcomes there and I’m excited to proceed down that path.
“This can be a powerful one, and I don’t know that we as a sport are at all times going to knock it out of the park there, however it’s going to proceed to evolve and we’ve gone in the proper instructions and I’m excited to proceed down that path as properly.”
NASCAR stated it hasn’t but decided the parameters and scope of the North Wilkesboro take a look at, together with what might be examined and what number of contributors.
