INDIANA — The NTT IndyCar Series has officially revealed its next-generation race car, introducing the Dallara IR-28 chassis and powertrain package scheduled to make its competitive debut in 2028.
The ground-up redesign replaces the long-serving DW12 platform (currently badged as the IR18) and is engineered to deliver faster lap times, closer wheel-to-wheel racing, and the highest safety standards in series history.
Lighter Weight, Elevated Power, and Record-Breaking Speed
The IR-28 platform addresses key feedback from drivers and teams, shedding approximately 100 pounds compared to the current car.
The performance package combines updated aerodynamics with a brand-new hybrid powertrain:
- Engine: Powered by a 2.4-liter twin-turbocharged V6 internal combustion engine capable of generating up to 760 horsepower.
- Evolved Hybrid System: Features a low-voltage battery-hybrid system that is roughly 20 pounds lighter than the current unit while offering significantly greater energy storage and deployment options.
- Aerodynamic Wake: Re-engineered front and rear wings reduce turbulent outwash, enabling cars to follow more closely through corners and creating clearer passing opportunities.
- Track Records in Sight: IndyCar officials designed the IR-28 to surpass current track records across North America—including Arie Luyendyk’s long-standing 1996 qualifying speed records at the Indianapolis Motor Speedway.
Safety and Cockpit Ergonomics
Built from the ground up by Italian manufacturer Dallara, the IR-28 features the most advanced monocoque in series history. Unlike the current chassis—which retrofitted safety measures over time—the IR-28 fully integrates the titanium aeroscreen, side-impact protection, and roll hoop into its core design.
Additionally, the cockpit has been expanded and redesigned to accommodate a broader range of driver heights and body types, while incorporating enhanced internal airflow and driver cooling systems.
Paddock and Driver Reaction
Drivers and team leadership voiced enthusiasm following the unveiling:
“Seeing the car for the first time made me even more excited about where INDYCAR is going,” said three-time series champion Alex Palou of Chip Ganassi Racing. “The design is super cool and feels like a proper next step for the series while still looking like an INDYCAR SERIES car… The most important thing is that we keep the close, fun racing that makes INDYCAR special.”
“There is a ‘wow’ factor,” added 2026 Indianapolis 500 winner Felix Rosenqvist. “The first thing that struck me is that it has more room in the cockpit and will fit differently-sized drivers, which is really good… Dallara has delivered on almost everything. I’m super excited for the future.”
Initial track testing for prototype models of the IR-28 begins this week as Chevrolet, Honda, and Dallara prepare for extensive on-track development ahead of the 2028 season opener.
