NDYCAR has unveiled the new NTT INDYCAR SERIES chassis and powertrain package for 2028, introducing a car with a modernized look designed to provide for faster lap times and improved raceability encouraging more wheel-to-wheel action, while also creating the safest car yet for “The Fastest Racing on Earth.”

Working with Dallara to produce the IR-28 chassis, the new car will make its competition debut at the start of the 2028 NTT INDYCAR SERIES championship. 

The IR-28 is equipped to exceed current lap times and capable of breaking track records, including at Indianapolis Motor Speedway, where the last track records – one-lap and four-lap qualification records – were broken in 1996 by two-time Indianapolis 500 presented by Gainbridge winner Arie Luyendyk.

As part of the improved raceability, the IR-28 will weigh approximately 100 pounds less than the current car. The more favorable power-to-weight ratio enhances raceability to allow drivers to push harder and deliver even more competitive racing and wheel-to-wheel action.

Previously announced, the 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. Low-voltage hybrid technology will also evolve 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 SERIES power unit. 

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.
