INDYCAR reveals next round of design for 2018 common aero kit
After the initial renderings of the 2018 common aero kit were released in January at the North American International Auto Show in Detroit, questions then turned to when INDYCAR would release the next round of what the future of the single kit would look like.
The date was something of a moving target, without a set time piece either just before or just after the 2017 Verizon IndyCar Series season began with the Firestone Grand Prix of St. Petersburg on March 12.
That being said, today marks the arrival of round two of what the new kit will look like, revealed first on IndyCar.com. The timing works well as it’s just after St. Petersburg but before Round 2, the Toyota Grand Prix of Long Beach, which runs April 9 at 4 p.m. ET on NBCSN to kick off the NBC Sports Group’s coverage portion of the season.
In today’s release, INDYCAR is still yet to confirm the supplier of the new common aero kit. But the car’s development remains on track to be revealed in the flesh this summer before a mid-summer testing debut.
“While this remains a work in progress, we are encouraged with where the development of the 2018 car stands,” Jay Frye, INDYCAR president of competition and operations, said in the release. “The look of the car is bold, the performance data from simulations is meeting targeted goals and safety enhancements built into the design will be substantial.”
Tino Belli, INDYCAR director of aerodynamic development, explained the design process with a focus on producing more downforce from the underside of the car rather than on top, addressing driver feedback.
“We’ve been working on the aerodynamics to suit the look, rather than the other way around,” Belli said in the release.
“We’re working on creating more of the downforce from the underwing,” Belli said. “The hole in the floor (of the undertray on this year’s car) will be sealed for the road courses and short ovals, but will still be open for the superspeedways.”
While aerodynamic targets and additional safety enhancements are set to include side impact structures in the sidepods and repositioned radiators, with turbocharger inlets moving to the inside of the radiator inlet ducts, no word was given today in terms of a windscreen or other cockpit protection enhancement device which has been rumored but not officially confirmed to be part of the 2018 kit. Belli said in the release that INDYCAR has achieved “97 percent” of its goals from developing the new car’s look and efficiency.
Of note, INDYCAR announced long-term contract extensions with four key partners, Dallara, Chevrolet, Honda and Firestone, at St. Petersburg, which was great news for the series but perhaps overshadowed in the kickoff to the new season. It further pushed the development of Frye’s much-mentioned “five-year plan” for the series.
Just because the base Dallara DW12 chassis remains as the tub does not necessarily mean it will be Dallara as the common kit supplier. Dallara’s Stefano De Ponti, director of the company’s U.S. operations, did say how much it has meant to the company to be celebrating its 20th year with INDYCAR during the St. Petersburg announcement.
“Dallara came here in 1997. That has marked the Dallara presence in North American motorsports. It was an important step,” De Ponti said at St. Petersburg.
“Obviously the plant, facility, engineering center we built in Indianapolis was, for the most part of it, obviously to support our program here as a partner with IndyCar.
“I personally wish, yes, that the extension will go beyond the set extension we have so far. We would like to be very, very clear, to be trustful and a supported partner of IndyCar as a manufacturer.
“Obviously, as an engineering company, we like competition, of course. We welcome everything that IndyCar decides to do with us for the future.
“At the end of the day, we want to be, and we are committed, to work with IndyCar for the benefit of the series. That would benefit all of us.”
