IndyCar has officially confirmed that Honda and Chevrolet will continue to serve as the official Original Equipment Manufacturers (OEMs) through at least 2028, with each manufacturer also owning a charter starting in 2028 to further deepen their involvement in the series.

Why it matters

This long-term commitment from the two leading engine suppliers provides stability for IndyCar as it transitions to a new era with a 2.4-liter, twin-turbocharged V6 engine paired with hybrid technology in 2028. The addition of charters for the OEMs also allows them to expand their presence beyond just engine development and supply.

The details

The agreements represent a significant financial investment from both Honda and Chevrolet in the series, as IndyCar continues to capitalize on growth and momentum. Both OEMs will play a central role in developing the engine for the next-generation car and powertrain package that the teams expect to integrate in 2028.

  • The 2026 season is set to begin March 1 at the Firestone Grand Prix of St. Petersburg.
  • The new powertrain is set to utilize a 2.4-liter, twin-turbocharged V6 engine paired with hybrid technology, to be announced in full at a later date.
  • Beginning in 2028, each OEM will be entitled to own a charter under INDYCAR's charter system, which was first introduced in September 2024.
