Jay Frye expresses positive outlook on 2018 car
In a teleconference with members of the media on Monday, the prevailing mindset of INDYCAR President of Competition and Operations Jay Frye, who helped oversee the design of the 2018 universal aero kit (pictured above in a Chevrolet livery), was one of positivity following it’s official unveiling, in speedway trim, earlier today.
First and foremost, though he helped head the effort, he was vocal about the input he got from a number of different entities during the process of creating the design.
“This has been a year and a half in the making, and the process has finally come to a point where we can get the car on the track, so we’re quite excited about that,” he revealed. “We certainly appreciate everyone’s help, from Dallara to the teams who have helped to the manufacturers who have helped and certainly the fans. Over the last few months we kept putting out some different things to get reactions from fans to see what they thought of the project. It helped us a lot, because it made us feel like we were going in the right direction, which is great.”
The overall timeline of the project dates back to last year, particularly at tests at Phoenix International Raceway and Mid-Ohio Sports Car Course, where the experimentation process began. It was after those tests, as Frye explained, that the 2018 car began to take shape. “From that point (after tests at Phoenix and Mid-Ohio), we took what we thought the car should look like, and that’s where we talked about reverse engineering the car and to aesthetically make it have a historical feel, but in a very forward car, and I think we’ve done that.”
And with the project now open for the public to see, Frye appears confident that people will like how it performs. “The numbers have come back very strong, which we’re quite excited about. And here we are coming up to tomorrow, where we’re going to have our first on-track test. It’s been a long process, but it’s been very methodical,” he added.
Specific to those numbers, two obvious areas stand out the most: cost and downforce. First, as Frye explained, the operating cost of the 2018 aero kit is expected to be considerably less in comparison to the current aero kits from Chevrolet and Honda. Further, the conversion costs, the money the teams will spend in switching their chassis over to the new kits, is less than expected, making the package significantly more economical. As Frye explained, this is a result of negotiations in which it was agreed that this package will be in use for at least three years.
“From a total cost perspective, one of the things we looked at is called a conversion cost. What would it cost to convert the cars now? It’s not as much as we first thought it would be,” Frye detailed. “The annual cost will be 30-40 percent less than what the current car is. One of the things with having a universal car is we were able to negotiate the term, which is for three years, so the teams can plan for it. That was something that was very important: what the conversion cost was going to be and what the annual cost was going to be over this term.”
And, in terms of downforce, there will be reductions in aerodynamic downforce as well as overall downforce. First, most of the car’s grip will be generated from the bottom of the car, whereas currently most of the grip is produced by airflow over the top of the car. As Frye explained, this not only is significant to the overall performance of the car and how it will race, but it also reduces the chance for large debris fields after an accident.
“Sixty to seventy percent of the downforce is generated from the bottom of the car, where as before it was 40-45 percent, so there’s been a big gain in that. Also, another piece to the puzzle, there are less parts and pieces on top of the car, which creates less debris opportunities,” said Frye.
Further, the overall package is expected to produce 20-25 percent less downforce, that estimation even accounting for teams’ ability to develop the chassis to find areas where downforce could be added.
Frye added that this was a key element in the design of the car. “What we tried to do is create a window, so the total potential window of the car’s downforce level has shifted down. Obviously, as the teams start running the car, they’ll get better and better and better, so we wanted to make sure to move it a different direction that, once downforce comes back to a degree, we haven’t exceeded this window we’re looking at,” he revealed.
And, of course, enhanced safety was a big factor as well. Frye discussed a particular emphasis on side impacts, especially in the wake of accidents involving James Hinchcliffe (2015) and Sebastien Bourdais (2017), in which they suffered serious injuries following side-on impacts with the wall.
“The side-impact piece that’s in this car is moved forward, the radiator is moved forward, so it’s also a much more robust protection piece for the side-impact of the drivers,” Frye described.
And, of particular note in the wake of the F1 Strategy Group revealing that a halo will be introduced in 2018, Frye added that cockpit protection remains at the forefront, and while nothing is set in stone at the moment, the new chassis has room for cockpit protection to be added.
“The cars are built and designed around having some sort of application like that,” Frye said of cockpit protections. “At some point, we’ll test something, whatever application we can come up with. We’re definitely conscious of it, we’re conscious of how it will affect aesthetically, we’re conscious of the safety piece.”
The Verizon IndyCar series will test the 2018 car at the Indianapolis Motor Speedway tomorrow, with Juan Pablo Montoya and Oriol Servia doing the driving, with additional tests scheduled for Iowa Speedway, Mid-Ohio Sports Car Course, and Sebring International Raceway later this year.
Soon after series testing is complete, Honda and Chevrolet will begin receiving chassis for their respective teams to test, with all IndyCar teams scheduled to receive their cars beginning in November. Individual team testing will then begin in January of 2018.
