IndyCar Paddock Enthusiastically Welcomes Next-Gen IR-28 Chassis

The IndyCar Series has unveiled the Dallara IR-28, a groundbreaking chassis and aerodynamic package poised to redefine open-wheel racing in 2028. This new iteration, replacing the long-standing DW12 platform, boasts a striking visual transformation, an integrated safety structure, significant weight reduction, and advanced aerodynamic features designed to facilitate more competitive, wheel-to-wheel racing. The reveal has been met with an overwhelmingly positive response from drivers and team principals across the paddock, who are eager to embrace the future of the series.

Drivers universally agree that the new vehicle exudes an immediate sense of speed and aggression. Marcus Ericsson, pilot of the #28 Andretti Global Honda, praised the seamless integration of the aeroscreen with the chassis and aerodynamic components, remarking, "The car looks aggressive and raw, and I love the integration of the aeroscreen with the rest of the chassis and aerodynamics. Dallara has made some really good steps." Reigning four-time IndyCar Series champion Alex Palou, representing Chip Ganassi Racing, echoed this sentiment, highlighting how the design successfully marries modernity with the series' core identity. He believes fans will appreciate the updated look while drivers will be thrilled to get behind the wheel, emphasizing the importance of maintaining IndyCar's signature close and exciting competition.

The design priorities for the IR-28 included a full integration of safety elements, particularly the Aeroscreen, directly into the car's tub, rather than as an afterthought. Will Power of Andretti Global Honda, a two-time champion and Indy 500 winner, expressed his admiration for the cohesive engineering, stating, "IndyCar 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’s also modern and aggressive at the same time." Dallara also focused on optimizing cockpit dimensions to comfortably accommodate drivers of varying physiques. Felix Rosenqvist, the reigning Indy 500 victor from Meyer Shank Racing, noted the improved cockpit space and confirmed that the IR-28 retains the distinctive IndyCar aesthetic, addressing driver requests with its aggressive design and integrated aeroscreen.

Discussion among drivers also centered on the new car's performance aspects, particularly how its reduced weight, refined underbody, and updated aerodynamics will minimize 'dirty air' and foster closer racing. Jack Harvey, serving as a pit reporter for FOX Sports IndyCar coverage, vividly described the unliveried car as resembling "Batman's new toy," emphasizing its aggressive yet naturally evolved appearance. He expressed optimism that the aerodynamic improvements would significantly enhance racing, even a minor increase in clean air making a substantial difference. Rinus VeeKay of Juncos Hollinger Racing pointed to specific aerodynamic enhancements, such as the barge boards, which are expected to greatly benefit oval racing. Conor Daly, who competed in the Indy 500 earlier this year, agreed that the new platform addresses key requests from the paddock, including weight reduction, improved aero grip, and more powerful engines. Alexander Rossi of Ed Carpenter Racing acknowledged the need for further on-track testing but praised the car's initial visual and foundational design. Kyffin Simpson of Chip Ganassi Racing concluded by expressing excitement for both the chassis and the anticipated performance of the 2.4-liter engine, believing it will elevate IndyCar to unprecedented levels.

IndyCar Unveils Revolutionary IR-28 Race Car

IndyCar has unveiled its state-of-the-art race vehicle, the IR-28, which is slated to make its competitive debut at the commencement of the 2028 season. This groundbreaking design, meticulously crafted in collaboration with Dallara, is poised to usher in a new era for open-wheel racing, promising unparalleled speed, heightened safety protocols, and intensified wheel-to-wheel competition across all racing disciplines.

The IR-28 represents a significant leap forward in racing technology, focusing on several key areas. It boasts a substantial weight reduction of approximately 100 pounds compared to its predecessor, which dramatically enhances its power-to-weight ratio for improved acceleration and braking. The car's aerodynamics have been completely re-engineered, featuring a purpose-built wake architecture designed to minimize dirty air and facilitate easier overtaking. This includes advanced front and rear wing configurations tailored for both road circuits and superspeedways. Furthermore, the integrated aeroscreen, now seamlessly built into the chassis, contributes to a lighter, sleeker profile, giving the car a distinctive "fighter jet" aesthetic. Inside the cockpit, mechanical anti-roll bar controls have been replaced with electronically adjustable systems, freeing up space and increasing responsiveness for drivers. The innovative AXIS inertance suspension system, a shared damping architecture, offers multi-mode tuning options, making IndyCar the sole major motorsport championship to permit both front and rear third-element inertance systems.

Under the hood, the IR-28 will be powered by a 2.4-liter twin-turbocharged V6 internal combustion engine, capable of generating up to 760 horsepower, with strong commitments from both Chevrolet and Honda. This hybrid powertrain incorporates a low-voltage hybrid unit from Helix, integrated within the bellhousing, and a cutting-edge battery-based Energy Storage System from BOLD Technology, providing 14 times the energy capacity of previous models for strategic power deployment. A newly engineered Xtrac transmission further reduces the car's weight by 25 pounds, optimizing overall performance. Beyond performance and design, safety remains paramount. The IR-28's wider cockpit accommodates a broader range of driver physiques, with improved internal airflow and cooling. Enhanced side-impact structures are designed to absorb higher kinetic energy during collisions, and optimized crash dynamics ensure the car stays grounded during high-speed incidents, meeting or exceeding both IndyCar and FIA safety standards. Extensive track testing for the IR-28 is commencing immediately at various venues, including the iconic Indianapolis Motor Speedway, ensuring its readiness to shatter records and deliver an exhilarating racing spectacle.

This visionary design signifies a commitment to pushing the boundaries of motorsport. By prioritizing innovation, driver safety, and spectator engagement, IndyCar is fostering a future where the thrill of racing is amplified, inspiring a new generation of enthusiasts and solidifying its position at the forefront of automotive competition.
