2028 will bring IndyCar’s first all-new chassis since 2012, with the IR-28 unveiled Tuesday as a lighter car built around the series’ aeroscreen and hybrid era.
About 100 pounds lighter than the DW12, the IR-28 adds new front and rear wings for superspeedways and road and street courses, with aero aimed at closer racing.
Honda and Chevrolet will stay on as engine suppliers under a new formula centered on 2.4-liter twin-turbo V6s producing up to 760 horsepower.
A new battery-based energy storage system is expected to deliver roughly 14 times the capacity of the current hybrid setup, while the bodywork also creates more space for manufacturers and sponsors.
The reveal gives IndyCar a long-delayed modernization after nearly 15 years on one base car, even as the 2026 season continues through a five-race run ending Sept. 6 at Laguna Seca.
