JOLIET, Ailing. — NASCAR is again at Chicagoland Speedway for the primary time since 2019, however it would possibly as nicely be the NASCAR Cup Sequence’ first time ever.
Regardless of 19 prior races on the 1.5-mile oval courting again to 2001, the Cup Sequence has by no means raced on the Joliet speedway with its Subsequent Gen automobile. That alone supplies an additional problem to crew chiefs forward of Sunday’s eero 400 (6 p.m. ET, TNT Sports activities, truTV, HBO Max, MRN Radio, SiriusXM NASCAR Radio).

All 38 groups acquired 50 minutes of apply on Friday afternoon, however three automobiles got here with some semblance of a reference level. Chris Gayle, crew chief of the No. 11 Joe Gibbs Racing Toyota and driver Denny Hamlin, received a step ahead with a two-day tire take a look at at Chicagoland in late April, incomes further laps together with the No. 5 Hendrick Motorsports group and No. 12 Crew Penske group.
“It is not big, however it is a bonus, proper?” Gayle instructed NASCAR.com on Saturday. “You get a leg up on the place the place is. You get to attempt just a few extra issues than what you’d have tried in a 50-minute apply session, proper? So our pocket book for, ‘OK, we have to do that many issues in apply and hustle by means of’ is just a little completely different than different guys. After which it offers you a baseline setting for, OK, I feel that is the place I want to come back again.
“However lots of automobiles that get on the race monitor and begin laying rubber down, and that form of all the time shifts your goal for stability the place you should be in comparison with the take a look at, and in order that’s all the time nonetheless just a little little bit of a guess and never gonna be absolutely mounted for you. However it helps. After which the driving force clearly has lots of expertise right here, however it’s been some time, so it form of refreshes (Hamlin) on what to anticipate on the primary few laps versus a few of these different guys that you just hear them on the radios, like, ‘oh my gosh, it is so tough. That is horrible.’ He is already tuned in and prepared for that.”

These bumps might create essentially the most distinctive take a look at this weekend. Different 1.5-mile tracks on the circuit function worn pavement, however seven years of unraced asphalt combined with the age of seven Chicagoland summers and winters have given the monitor’s growing old pavement years of character improvement that may make any Hollywood director proud.
“I feel the bumps are actually aggressive,” Gayle stated. “Significantly, two completely different kinds, proper? There’s principally an enormous spike bump in (Turns) 3 and 4 on the tunnel, which has an enormous amplitude. After which Flip 1 is just a little completely different, the place it is received form of an extended period of bumps, however quite a bit larger frequency on the best way in. So I feel you get the number of every little thing. It feels tough usually in every single place, and there are massive seams and cracks, and so they’ve needed to fill lots of that.”
Rudy Fugle, crew chief of the No. 24 Hendrick Motorsports Chevrolet and driver William Byron, described that number of bumps by means of Turns 1 and a couple of as “ripple bumps” and “washboard bumps.” There’s a explicit part of bumps on the finish of the frontstretch, although, that has caught Fugle’s eye.
“The stumble upon Flip 1, which has been there ceaselessly, it is a patch. However now it is a launch level,” Fugle instructed NASCAR.com. “You virtually take off. It jogs my memory of just a little little bit of San Diego, the place a few of us have been airborne. I do know the automobiles aren’t airborne, however the automobile will get tremendous, tremendous gentle by means of there, so it is a massive, massive leap.”

That added texture locations duty on the crew chief, who should arrange the automobile for clean straights and numerous monitor surfaces all through every 1.5-mile lap.

“You need to make the automobile experience over the bumps and never hit the race monitor in numerous methods,” Fugle stated. “There’s bumps right here that the automobile bottoms out, and really the underside of the automobile hits the monitor. There’s loads of bumps the place you hit the (shock) cease limiters that we discuss on a regular basis, and that is a ride-quality factor we attempt to discover. It is a nice line. We attempt to be on one aspect or the opposite of that, however we’re proper on the sting of it.”
With added monitor texture comes the query of tire put on. Fugle stated the tire put on he noticed in Friday’s session did not deviate a lot from different mile-and-a-half tracks on the circuit like Kansas Speedway or Texas Motor Speedway, with Gayle noting “it’s going to be Charlotte-ish.” However how they handle eight new units of Goodyear tires all through a 267-lap race will assist dictate the result Sunday — significantly in a rash of fast cautions.
“I will likely be stunned in the event you get 20, 25 laps in, if there’s any various methods,” Gayle stated. “I feel you are going to need tires and also you’re in all probability going to need 4 at that time. I simply am interested by working out of tires, possibly. Like, you’d need them each time you get cautions, and I feel that is simply going to be about these cautions, proper? When you get the short cautions which might be solely two or three laps on tires on a restart, then everyone’s secure. It is once you get these each 15 laps that you possibly can in the end be brief on tires.”

That exact concern could also be each crew chief’s nightmare.
“Each time the cautions come out each 10 laps, you are scared to loss of life,” Fugle stated. “The five-lap cautions are, they’re form of enjoyable as a result of you’ve the chance to commerce and get forward of one thing. When you pit (after) the 5 laps, it is in all probability not suggested, however in the event you get one other one in 5 laps, everyone in entrance of you goes to pit, and you then get to remain, so a few of these are enjoyable. However once you get to 10, 12, 15 laps on tires and also you stack these, you get actually scared.”
However how lengthy will tires final on a given run? That reply might change between Friday’s apply and Sunday’s checkered flag.
“At most of those intermediates, we might see cords in 35 laps,” Gayle stated. “I do not assume anyone ran that lengthy (in apply) with the variety of tires we had yesterday. Someone I believed ran 29 or 30, however I by no means heard of any cords or something. However once more, we’ll must go 40, 42, laps within the race, possibly just a little longer (with) Stage 3 going inexperienced. I feel it’s going to be OK by then, however for as abrasive as it’s, I feel it is extra in regards to the bumps and dealing with these as a result of the fall-off is not all that completely different than a Kansas or anyplace else.”
