New aero kits handling fine, if not better than expected, in Indy’s dirty air


INDIANAPOLIS – One of the biggest elements of the Indianapolis 500 since the introduction of the Dallara DW12 chassis in 2012 has been the tow effect, which was even more prevalent with the new car compared to the old car used through 2011.

That determined how big of a run someone could get in a draft and how they would be able to catch up, and/or pass someone going into the corner.

With the introduction of manufacturer aero kits this year, and with the super speedway version of the kits making their debut on Sunday, drivers explained the terms of the effect that the kits have in terms of dirty air and turbulence.

In many respects, it appears the air isn’t as dirty as anticipated for cars in traffic. But there doesn’t seem to be as big of a tow, and passing hasn’t looked to be as easy as it has been in recent years – particularly the slingshot-heavy 2013 race that featured a record 68 lead changes.

Jack Hawksworth, driver of the No. 41 ABC Supply Co. Honda, told MotorSportsTalk earlier this year that on a street course, when you’re behind multiple cars, the dirty air is quite prevalent. But at the Indianapolis Motor Speedway oval, it hasn’t been that bad.

“I’m actually pretty comfortable now,” Hawksworth said during IMS media day on Thursday. “In a big train, 10-15 cars, it’s a bit tricky. You’ve got vortexes going everywhere! But two to three in front of you is pretty straightforward.”

While Hawksworth is making his second ‘500 start from 28th, Oriol Servia will make his seventh start from 13th in the No. 32 Rahal Letterman Lanigan Racing Honda.

Servia is a veteran in either CART or IndyCar dating to 2000 and as such, has driven a variety of different chassis, engine, and tire combinations, with different horsepower levels and aerodynamic configurations.

This car, he said, isn’t as bad in dirty air but is more difficult to pass with at times.

“Actually you can get close to the cars pretty good. But I’m finding it harder to complete the pass,” Servia said. “It seems like you ‘suck’ less. There’s less of a tow and maybe you cannot finish the pass like you did last year. It’s gonna be hotter and who knows how that will change it.”

Servia has started higher in the race – he rolled off third in his final start with Newman/Haas Racing in 2011 – but feels better about his chances on Sunday regardless of how the car feels in turbulence.

“I actually feel better even in the race situation than qualifying,” he said. “So I’m so excited now. It’s the best shot I’ve had. The car felt great from day one. It feels really good on the ground.”

Those two are Honda drivers. A pair of Chevrolet drivers – and CFH Racing teammates in Josef Newgarden and JR Hildebrand – also think the aero effect of the new kits in dirty air hasn’t been as bad as feared.

“They feel about the same… really similar to last year,” said Newgarden, who will start ninth in the No. 21 Century 21 CFH Racing Chevrolet, and had one of the month’s airborne accidents.

“If anything it seems some guys can follow closer. I think overall it’s about the same in terms of how they race from my perception of what I notice.”

Newgarden confirmed the aero kits had nothing to do with his accident. He said while it’s good there’s been extra attention on the race this month, it’s also added some undue drama, which isn’t particularly needed.

Hildebrand – who’s a scientific whiz with his work doing STEM education for young fans at schools, deferred acceptance to MIT and will start 10th in the No. 6 Preferred Freezer CFH Racing Chevrolet – provided the most technical explanation of the air effect on this year’s cars.

“I was anticipating it would be harder to be closer to other cars as compared to last year,” he explained. “For a lot of the week we did think that. It speaks to the sensitivity of the package. Assuming it doesn’t rain, you’ll see as close as racing as you’ve ever seen. It’s not a big pack of cars, but a lot of guys can run quite close.”

Lastly from a year-to-year, Indy Lights to IndyCar perspective, Bryan Herta Autosport’s Gabby Chaves explained how different it is running in these cars in dirty air compared to the tighter groups that punctuated the Freedom 100 races.

“It’s a lot harder at the greater speeds and greater downforce,” said Chaves, driver of the No. 98 Bowers & Wilkins/Curb Honda, who will make his race debut from 26th on the grid.

“It creates this domino effect where the guy in front, he’s gotta back up. It’s much harder to race and you’re setting up a pass every corner. As opposed to Indy Lights where if you get really close, sure. But you can essentially run two-wide and be anywhere on the track.”

Both Monday’s second practice and Friday’s one-hour final practice have witnessed close racing, and a suitable amount of “suck up” in dirty air, without passing being as relatively easy – at least from the outside – as it has appeared in recent years.

It will be fascinating to watch how the cars handle this year, to see what position is best to be in as drivers carve through the field in the first race with the new manufacturer super speedway aero kits.

IndyCar has big plans on, off track for first test at Thermal Club: ‘It’s an amazing facility’

PALM SPRINGS, Calif. – Quantity isn’t a problem for NTT IndyCar Series drivers seeking source material for their first test on track at The Thermal Club. There’s plentiful video of the drivers making laps on the private track that bills itself as a world-class facility.

It’s quality that’s an issue with trying to do homework for their first (and possibly last) test on the 17-turn, 2.9-mile road course.

Thermal is billed as a motorsports country club of sorts, giving the rich and famous an opportunity to drive and store vintage cars at racing playground that has more than 200 members and $5 million, 30,000-square-foot homes sprouting constantly.

IndyCar’s arrival Thursday and Friday for its first full-field open test in the preseason since 2020 will mark a new era of professional racing at Thermal, which primarily has catered to amateurs (often in a fantasy camp-type setting).

Colton Herta tried doing some YouTube research on Thermal recently but gave up after watching the third lap of “some dude in a Ferrari” navigating the course that is nestled in the Coachella Valley just south of Joshua Tree National Park and north of the Salton Sea.

“It’s difficult to watch some of the onboards because it’s not really professional drivers, and they have like the cones set out on the track, where to turn in and where to get on the brakes, so it’s kind of irrelevant,” Herta said. “Yeah, I watched a little bit before I got too bored and turned away. But the track walk will be important. That’s going to be the biggest thing.”

The track walk happened Wednesday afternoon after two days of wall-to-wall media obligations at the Palm Springs Convention Center.

Conor Daly and Scott McLaughlin were among many drivers who were antsy to head southeast to the ritzy track (where many drivers have been staying in high-end casitas on the 470-acre property this week). Herta said his main concern was having enough runoff area as drivers knock off the offseason rust because “you do tend to drop a wheel here and there, have a spin if you’re getting back in the car for the first time in a few months.”

“I sort of don’t really know where the track goes,” McLaughlin said. “I feel like I’m going to get lost out there.”

With IndyCar increasingly limiting test time, Daly said sessions such as Thermal “are really, really important. We can train all we want, but there’s nothing like getting in these cars to drive to really prepare yourself for the first race. It’s going to be important to try to do as many laps as possible.”

Of course, what makes Thermal even more rare is that it’s not on the IndyCar schedule nor has it been a testing venue in the past. Sebring International Raceway also doesn’t play host to a race, but it’s become a tried and true place for teams seeking to hone their setups.

Thermal will be the first time IndyCar is learning an entirely new track since the streets of Nashville nearly two years ago, but in this case, it’s unknown how applicable it’ll be in the future. Some drivers speculated that it could translate to Portland with its length (lap times are projected at more than a minute and 40 seconds), but it’s an unknown how slippery the surface will be for tire wear (probably 20-lap stints, which are relatively short).

“It’s hard when it comes to just two full days of testing because obviously some people will adapt to it quicker than others,” Daly said. “You might feel like a hero, then the next day you might feel like a zero because some people have caught up.

“But these days are important because hopefully it is an indication for us on all the permanent road circuits that we go: Mid-Ohio, Laguna Seca, Indy GP. Hopefully it’s helpful for us in all those scenarios. We’ll see what happens, I guess. It doesn’t matter to us how fast we go, as long as we get something out of it, right? How do we judge some changes? If that’s great for a certain section of the track, right, that could represent a section of another road track we go to. There’s a lot that we can learn, for sure. Realistically we kind of have to keep ourselves  in check with our expectations.”

Two-time series champion Josef Newgarden said drivers “probably shouldn’t come out of here either too excited or too demoralized depending on how it goes because it is not incredibly relevant when it comes to at-track performance. We’re never going to run here again. Well, I shouldn’t say that. We’re not going to run here this year for a points-scoring race. From that standpoint, it’s not relevant.

“What it is relevant for and what I’m excited about is just being on track. We definitely need it on the 2 car. We have a lot of new people. We’re going to maximize this time by just treating it like a race weekend in that we’re doing all the things we would do on a normal weekend to be fast and work well and efficient together. When we come out of the weekend we’ll have something to look at, what did we do well or not well. We have a good, relevant conversation piece to take into (the season opener at) St. Pete. From that standpoint it’s excellent. If we finish 15th on the charts, yeah, maybe we shouldn’t read too much into that.”

Said Rahal Letterman Lanigan Racing driver Graham Rahal: “I’m not sure how much (the Thermal track) relates. We’re running a Barber tire, similar to the Laguna Seca tire. Who knows what the track grip is like in the desert here. If you look at a lot of the corners, a lot of hairpins, a lot of slow speed corners, but then you’ve got like the end of the back straight is quite a fast left-hander. But they’re varying shapes of corners, decreasing radius, on increasing radius. We don’t have any tracks that do that traditionally.

“We’ve got to pick and choose exactly what we get out of it, but I’m all on board for the Thermal thing, so I don’t want to sound like I’m not. I think it was great to have change. We’ve kind of gone to the same places time and time and time and time again. It’s good to see something new.”

IndyCar also will be measuring the results of the test beyond timing and scoring.

The Indianapolis Star reported there have been informal talks about having a pro-am event in the future. With the test closed to the general public but open to its high-dollar clientele, there could be potentially millions of liquid capital at stake for future team investment if the Thermal Club’s members take a shine to IndyCar.

Thermal was throwing a posh welcoming event Wednesday night that was expected to have drivers, series executives and residents mingling with dancing and drinks.

Simon Pagenaud, who has explored the concept of starting a motorsports country club in his native France, is intrigued by the long-term marriage of IndyCar and Thermal.

“This kind of racetrack — what they do with their members, the passion of cars —  is really something,” Pagenaud said.

Indy 500 winner Marcus Ericsson likes the appeal of testing in Southern California instead of Central Florida.

“This time of the year, it’s really hard to find places for us to go testing,” Ericsson said. “I’ve only been here for four years, starting my fifth year, and I feel like I’ve done I don’t know how many days of testing at Sebring.

“For me, this is a lot better to come here. I like the idea a lot of having the preseason testing back on the calendar to get all the teams and drivers together.”

Said Alexander Rossi, who will be making his debut in an Arrow McLaren Chevrolet this week: “It’s always a difficult situation in January, February, in the United States to find a track that has the appropriate climate. Not only do we have a beautiful place to come with seemingly good weather, but you’re introducing IndyCar to obviously a demographic that has an interest in racing, with some decent capital behind them. They may not know of IndyCar. They may have known of IndyCar but never seen it in person.

“We’re able to bring and showcase what we believe is the best series in the world in front of people who are passionate about motorsports, participate in motorsports themselves, and maybe haven’t seen it before.”

McLaren teammate Felix Rosenqvist already has been staying at the villas inside the track all week.

“It’s an amazing facility,” he said. “I’ve never been here before. I was really blown away by how neat and tidy everything looks.

“I don’t know if there’s ambitions to race here in the future. That could be an option. I’m just pumped to be in California in January. There’s worse places to be.”
