Introduced on Tuesday, this new package will aim to check off multiple items. It will have the goal of delivering faster lap times and improving racing action while continuing to protect the competitors putting their lives on the line each week of the season.
The Dallara chassis will feature one of two powertrains, depending on the teams spaced out on the grid. They will have updated powertrains from Chevrolet and Honda that deliver more torque and power.
Specifically, these powertrains will be 2.4-liter twin-turbocharged V6 internal combustion engines that can produce up to 760 horsepower. They will still have hybrid technology that provides greater power storage at a lighter weight.

The IR-28 will weigh approximately 100 pounds less than the current IndyCar entries being used this season. It will have new front- and rear-wings for the various speedways and road courses on the schedule.
"What a sight," said Tony Kanaan, Arrow McLaren Team Principal. "I sat in the car and, in the past three years, I haven't had the itch to drive again as much as I did sitting in it. The car looks beautiful, futuristic and very impressive.
"Aerodynamically, it looks a lot quicker - and if it looks quicker, it's going to be quicker. The safety considerations are a key aspect and well thought out, as well. Thank you, IndyCar and Dallara. I can't wait, and I'm excited about the future."
Additionally, the updated bodies are designed to allow cars to race closer together in the corners of the various courses. They will have expanded real estate for sponsor decals.
The IR-28 will also have an updated cockpit with fewer handles and knobs, which should improve driver safety. The drivers will have electronically controlled adjustable anti-roll bars.
The cars will not make their competition debut until the start of the 2028 season, but they will have track time. Testing for the new cars begins this week as the series and its key partners try to dial in the product. This way, the new cars can immediately deliver exciting wheel-to-wheel racing.
"Seeing the car for the first time made me even more excited about where IndyCar is going," said four-time champion Alex Palou. "The design is super cool and feels like a proper next step for the series while still looking like an IndyCar Series 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've seen, we're heading in a really good direction."
