By John Sturbin, Raceday San Antonio<\/em><\/p>\n

INDYCAR has fast-forwarded to 2028 with the official unveiling of its new NTT IndyCar Series chassis and powertrain package. The modernized IR-28 is designed to provide faster lap times, more wheel-to-wheel competition and the safest open-wheel car ever.<\/p>\n

Working in collaboration with Dallara on the IR-28 chassis, the new car will make its competition debut at the start of the 2028 NTT IndyCar Series championship. First renderings of the IR-28 were shared Tuesday morning in Indianapolis via a video narrated by Matt Damon, Academy Award winner and star of the box office hit The Odyssey<\/em>. A link to the introductory trailer is available here<\/strong><\/a>.<\/p>\n

\u201cWe are pleased to unveil renderings of the new NTT IndyCar Series chassis that will take our sport into an exciting new era,\u201d INDYCAR President J. Douglas Boles said in a series news release. \u201cAs you can imagine, a project of this magnitude takes an incredible amount of planning, collaboration and execution. I would like to thank all of our partners including Dallara, Chevrolet, Honda, Firestone and Shell, who have worked tirelessly to create a package that will enhance INDYCAR\u2019s already incredible competition and industry-leading growth.<\/p>\n

\u201cWith initial testing to begin this week, there is still plenty of work to do before 2028. But we are well on our way to showcasing a new era of INDYCAR, which will include enhanced wheel-to-wheel competition, track records, standards in race-ability and new benchmarks in safety. We are confident the IR-28 is the ideal package to move INDYCAR forward for our teams, drivers, partners and fans.\u201d<\/p>\n

The new car continues INDYCAR\u2019s partnership with Dallara Automobili, founded by Giampaolo Dallara in 1972 in his hometown of Varano de Melegari, Parma, in the Italian Motor Valley. Dallara cemented its commitment to INDYCAR in July 2012 when it opened its American headquarters and engineering center in Speedway, Ind., a short distance from the Indianapolis Motor Speedway. The Dallara IndyCar Factory is a multi-functional center for research, development and assembly.<\/p>\n

“We are honored that INDYCAR has chosen Dallara once again,\u201d said Dallara USA Chief Executive Officer Stefano dePonti. \u201cAfter more than a decade of partnership, their continued trust is the greatest recognition of our team’s efforts. This achievement demonstrates the dedication, expertise and collaboration of many individuals who worked tirelessly to create a car that meets today\u2019s needs while looking toward the future. It also reflects Dallara\u2019s ongoing commitment to investing in innovation and education, sharing the knowledge developed in motorsport with academia and beyond.”<\/p>\n

Competition and Track Records<\/strong><\/p>\n

The NTT IndyCar Series is recognized as an intense and ultra-competitive championship, and the new car has been designed to build on that race-ablity while enhancing speeds via additional power. The IR-28 is equipped to exceed current lap times and capable of breaking track records, including at the 2.5-mile Indianapolis Motor Speedway. The last qualification records at IMS _ one-lap (237.498 mph) and four-lap\/10-miles (236.986 mph) _ were established in May 1996 by two-time Indianapolis 500 champion Arie Luyendyk of the Netherlands.<\/p>\n

Nicknamed \u201cThe Flying Dutchman,\u201d Luyendyk set those marks in the No. 5 Reynard 94I\/95I chassis powered by a Ford Cosworth XB engine fielded by Byrd-Treadway Racing.<\/p>\n

The IR-28 will weigh approximately 100 pounds less than the current car. The more favorable power-to-weight ratio theoretically will allow drivers to push harder and deliver more competitive, wheel-to-wheel action.<\/p>\n

New Car Design<\/strong><\/p>\n

Design of the new NTT IndyCar Series car begins with a sleek and modern look while retaining the unmistakable DNA of past iconic series cars. The entire car is newly designed and built from the ground up, ensuring many noticeable differences from the current car.<\/p>\n

New front and rear wings, optimized for style and efficiency, give the road and street course car an aggressive stance, while the superspeedway wing configuration provides maximum downforce with limited drag in a sleek, high-speed package.<\/p>\n

For the first time, the car\u2019s aerodynamic architecture has been purpose-built to optimize the wake from the front to the back in order to enhance overtaking opportunities. Additional benefits of the 2028 design include reduced outwash and, for Indianapolis Motor Speedway, a more aerodynamically stable speedway front wing.<\/p>\n

The IR-28 aeroscreen, designed into the development of the car, is lighter, sleeker and more aerodynamic _ supporting safety, race-ability and giving the IR-28 a fighter jet look and feel.<\/p>\n

Each bodywork element has been designed to result in closer on-track competition as the new aerodynamics will allow cars to follow more closely in corners and throughout the field.<\/p>\n

For the driver, the new car will feature electronically controlled driver adjustable anti-roll bars, which will provide for enhanced tuning while cleaning up the cockpit by eliminating standard knobs and handles, thus, also improving driver safety.<\/p>\n

\u201cSeeing the car for the first time made me even more excited about where INDYCAR is going,\u201d said Spaniard Alex Palou, the four-time\/reigning series champion and driver of the No. 10 DHL Honda fielded by Chip Ganassi Racing. \u201cThe design is super-cool and feels like a proper next step for the series while still looking like an INDYCAR car. I think the fans are going to love it, and as a driver I cannot wait to get behind the wheel. The most important thing is that we keep the close, fun racing that makes INDYCAR special, and from what I\u2019ve seen, we\u2019re heading in a really good direction.\u201d<\/p>\n

Additional updates for the IR-28 include introduction of the Custom AXIS Inertance Control Suspension System. Built around a lightweight, shared damping architecture, the AXIS platform expands spring, damper and inerter tuning options without increasing costs. Its highly-tunable, multi-mode design improves mechanical grip through suspension optimization, reducing reliance on aerodynamic load while giving teams significant setup flexibility.<\/p>\n

The NTT IndyCar Series is the only major motorsports championship to permit both front and rear third-element inertance systems, making the IR-28 one of the most advanced suspension platforms in modern motorsport.<\/p>\n

From a fan and commercial perspective, the new car will feature a digital car position display showing the position of the car in practice, qualifying and races and a unique transparent window in the engine cover which will highlight corporate partners Chevrolet, Honda and any additional manufacturer branding. Design updates for 2028 also include more visible surface areas for series and team sponsorship.<\/p>\n

2028 Powerplant<\/strong><\/p>\n

As previously announced, power for the new 2028 NTT IndyCar Series machinery will be provided by 2.4-liter twin-turbocharged V6 internal combustion engines capable of producing up to 760 horsepower. Chevrolet and Honda have committed to participate under the new engine formula, which will deliver increased torque, power and overall performance compared to the current generation of their engines.<\/p>\n

\u201cEveryone at Chevrolet is looking forward to this next era of the NTT IndyCar Series and the debut of the IR-28 in 2028,\u201d said GM Vice President of Global Motorsports Competition Eric Warren. \u201cThis new car builds on more than a decade of collaboration with INDYCAR, and we\u2019re confident the new 2.4-liter, twin-turbo V6 engine will deliver the performance, sound and excitement INDYCAR fans expect from Team Chevy _ the same standard that has produced 16 manufacturer championships and 13 Indianapolis 500 victories.\u201d<\/p>\n

Honda entered INDYCAR competition in 1994 under the badge of Honda Performance Development.<\/p>\n

\u201cFor more than 30 years, Honda has built upon its racing heritage as a key partner of the NTT IndyCar Series, and we are excited to begin this next chapter with the IR-28 powered by our new American-made HRC V6 Hybrid powertrain,\u201d said Honda Racing Corporation USA President David Salters. “INDYCAR delivers some of the best racing on the planet, and this evolution of the formula creates new opportunities to enhance it _ a lighter car, a more powerful hybrid powertrain, an even safer chassis and aerodynamic engineering challenges for our Honda associates and teams.<\/p>\n

\u201cTogether, these advancements will help usher INDYCAR into a new era. Honda is proud to be part of that future, supported by the long-term commitment we made to the series earlier this year. We can\u2019t wait to see the IR-28 on-track entertaining our INDYCAR fans.”<\/p>\n

Low-voltage hybrid technology evolves in 2028 and beyond with greater power storage, more deployment options for teams and a package that is approximately 20 pounds lighter than the previous INDYCAR power unit. The significant performance advancement and deployment variability will be provided through a new partnership with UK-based Helix, a global leader in next-generation solutions in building and delivering electric drive systems.<\/p>\n

With a client list that has included teams in FIA Formula One and FIA Formula E, and track-proven innovation that drives the Hypercars of tomorrow, Helix\u2019s hybrid design for the NTT IndyCar Series remains packaged inside the bellhousing _ located between the combustion engine and the gearbox.<\/p>\n

The new hybrid platform will feature the first battery-based Energy Storage System (ESS) in series history, supplied by BOLD Technology, selected by INDYCAR for the program. Headquartered at the Circuit de Barcelona-Catalunya in Spain and expanding its U.S. operations in Michigan, BOLD develops advanced battery systems for Formula One, aerospace and defense applications.<\/p>\n

Its ESS for the IR-28 delivers approximately 14 times the energy storage capacity of the current supercapacitor-based system _ giving drivers and teams far greater flexibility in when and how they deploy hybrid power _ while contributing to the lighter, safer power unit package, engineered and qualified to the most stringent motorsport safety standards.<\/p>\n

Xtrac, an exclusive supplier for INDYCAR since 2000 and a Helix associate, is providing transmissions for the new chassis. Development includes a gearbox that sheds 25 pounds from the current unit.<\/p>\n

Safety Evolution<\/strong><\/p>\n

While the IR-28 provides quicker lap times, increased speeds and will allow for more on-track action, it also is designed to keep drivers safer than ever. From the aeroscreen to the roll hoop to side-impact structures, the new car seamlessly integrates recent safety and design advancements into its core architecture. Built to exceed INDYCAR or FIA specifications, whichever is more stringent, the new chassis delivers measurable safety improvements over the current car, including:<\/p>\n

Driver cockpit _ The chassis features wider internal dimensions to accommodate a greater range of driver heights and body types. The IR-28 also features enhanced internal airflow and driver cooling for improved comfort and performance.<\/p>\n

Side impact protection _ Decades worth of race and incident evaluations _ including chassis additions _ have created a chassis that features stronger, more efficient side-structure design providing increased energy absorption in high-impact situations.<\/p>\n

Crash dynamics _Improved stability with a natural tendency to remain grounded during \u201cnose-up,\u201d sliding or spinning incidents.<\/p>\n

An extensive initial testing schedule for the IR-28 will include a variety of circuits and layouts from Indianapolis Motor Speedway\u2019s Road-Course and famed oval, Sebring International Raceway in Florida and more. Testing schedules and media availabilities will be provided at later dates.<\/p>\n

What Select Drivers Are Saying<\/strong><\/p>\n

\u201cThe car is awesome,\u201d said Alexander Rossi, winner of the landmark 100th<\/sup> Indy 500 in 2016 and driver of the No. 20 Java House Chevrolet fielded by Ed Carpenter Racing. \u201cWe all wanted a new, modern-day car that is lighter and looks futuristic and fast but still has all of the incredible safety advancements that INDYCAR is known for. This does all of those things. There are still a lot of things to work through in terms of on-track testing and how it reacts to the different types of environments it will be exposed to, but from a visual standpoint, it\u2019s incredible. This is something people will be excited about.\u201d<\/p>\n

Reigning Indy 500 champion Felix Rosenqvist of Sweden said there is a \u201cwow-factor\u201d attached to the new car. \u201cThe first thing that struck me is that it has more room in the cockpit and will fit differently-sized drivers, which is really good,\u201d said Rosenqvist, driver of the No. 60 SiriusXM Honda fielded by Meyer Shank Racing with Curb Agajanian. \u201cSecondly, it definitely has the INDYCAR DNA, which was a worry for me that it wouldn\u2019t look like an INDYCAR car. This definitely does. It also has an aggressive look with an integrated aeroscreen and a car that addresses a lot of little tweaks that drivers have asked for. Dallara has delivered on almost everything. I\u2019m super-excited for the future.\u201d<\/p>\n

Two-time series champion Will Power of Australia, winner of the 2018 Indy 500, gave his approval to the new car\u2019s cockpit.  \u201cI was just as excited to see what was inside the car as I was to see what it looks like on the outside,\u201d said Power, driver of the No. 26 TWG AI Honda fielded by Andretti Global. \u201cINDYCAR and Dallara have done an incredible job combining updated aerodynamic ideas with all of the safety elements from the current car. It has a seamless look and one that\u2019s also modern and aggressive at the same time.\u201d<\/p>\n

Sweden\u2019s Marcus Ericsson, the 2022 Indy 500 champion and Power\u2019s Andretti Global teammate, said the car \u201clooks aggressive and raw.\u201d  The driver of the No. 28 Delaware Life Honda added, \u201cI love the integration of the aeroscreen with the rest of the chassis and aerodynamics. Dallara has made some really good steps. They have improved so many areas both inside and out. I jumped in and quickly got the urge to take it for a spin. I wish we could go sooner than 2028.\u201d<\/p>\n

Team Penske\u2019s Scott McLaughlin said the car \u201cjust looks racy\u201d even when standing still. \u201cIt\u2019s refined, very well thought-through and filled with details both inside the cockpit and out,\u201d said McLaughlin, a native of New Zealand and driver of the No. 3 DEX Team Penske Chevrolet. \u201cPlus, it\u2019s kept the core INDYCAR feel while expanding our technology and taking this to another level.\u201d<\/p>\n

Series veteran Graham Rahal joined the choir praising the new car\u2019s design elements. \u201cIt\u2019s very striking and aggressive in many ways but isn\u2019t too far of a departure from the old car, which is exactly the way it should look,\u201d said Rahal, driver of the No. 15 Fifth Third Bank Honda fielded by Rahal Letterman Lanigan Racing. \u201cI was the \u2018tall driver\u2019 used for the seat-fit and initial sizing of the cockpit, so I\u2019ve seen the new chassis, and I have to say it\u2019s beautifully built especially with the way everything is integrated with the aeroscreen and everything else.<\/p>\n

\u201cOne of our goals should be to attract another manufacturer into the sport, and I hope this new footprint allows for that. I expect everyone to be very pleased.\u201d<\/p>\n

Arrow McLaren Team Principal Tony Kanaan, the series champion in 2004 and Indy 500 winner in 2013, said the new car has him rethinking retirement.<\/p>\n

\u201cWhat a sight. I sat in the car and, in the past three years, I haven\u2019t had the itch to drive again as much as I did sitting in it,\u201d the popular Brazilian said. \u201cThe car looks beautiful, futuristic and very impressive. Aerodynamically, it looks a lot quicker _ and if it looks quicker, it\u2019s going to be quicker. The safety considerations are a key aspect and well thought-out, as well. Thank you, INDYCAR and Dallara. I can\u2019t wait, and I\u2019m excited about the future.\u201d<\/p>\n

Dutchman Rinus VeeKay, currently 10th<\/sup> in the driver standings, said the new car checks several boxes for him.<\/p>\n

\u201cIt still looks like an INDYCAR car but so much more modern, integrated and racy,\u201d said VeeKay, driver of the No. 76 Juncos Hollinger Racing Chevrolet. \u201cOver the last few months, we\u2019ve heard bits and pieces about the wings or sidepods, but to see it all put together _ it\u2019s better than the expectations. Even details like the barge boards behind the front wheels, I think it\u2019ll help the racing a lot, especially on ovals. And the car is lighter. I cannot wait to hop in and give it a go.\u201d<\/p>\n
