Chevy and Honda confirm IndyCar contract extensions

Chevrolet and Honda will continue supplying the IndyCar Series with engines in new multi-year contracts.

The confirmation comes as both car companies headed into the final season of their existing contracts and ensures the series will have at least two manufacturers involved with its new-for-2028 chassis and engine formula. The first-time issuance of manufacturer charters is also part of the agreement.

“This is a monumental day for IndyCar, fueled by a massive and historic commitment from two of our best and most trusted partners,” said IndyCar President Doug Boles. “Chevrolet and Honda have worked tirelessly with us over the last 12 months to get to this point, and both have made it very clear that they are fully committed to this sport and invested in continuing the positive momentum the series generated in 2025.”

Chevrolet made its official entry into the CART IndyCar Series in the 1980s and will push into its sixth decade of participation with the new supply agreement.

“Chevrolet has enjoyed a long, successful relationship with IndyCar as an engine manufacturer, and this extension paves the way for the IndyCar Series to continue to grow and for us to further maximize technology transfer from race to road,” said General Motors President Mark Reuss. “The addition of a charter allows Chevrolet to join with other stakeholders to continue to make the series even stronger. IndyCar produces consistently exciting racing on road and street courses as well as ovals, and we look forward to building on our IndyCar legacy and put on a great show for our loyal Chevrolet fans.”

Honda joined the CART series in 1994 and has not left.

“To our esteemed Honda fans, customers and associates, we are thrilled to announce our ongoing participation in the IndyCar Series,” said Honda Racing Corporation USA president David Salters. “With a deep respect for the history and competitive spirit of IndyCar racing, we are proud to continue our involvement after more than 30 years. This longstanding commitment strengthens our ability to allow us to further develop our people and technology at the pinnacle of open-wheel racing in North America.

“The partnership between IndyCar and FOX continues to grow, bringing outstanding race coverage and elevating the experience for fans everywhere. The future of IndyCar looks incredibly bright, and we at Honda are honored to play a critical role in its continued success.”

As RACER revealed, Chevrolet and Honda will become members of IndyCar’s charter program in 2028 and have the right to enter a single factory car. Manufacturers can engage an IndyCar team to run their respective cars, but with teams limited to fielding a maximum of three cars under their charter agreements, the car companies are restricted to working with one- or two-car teams if they choose to outsource their programs.

“As charter entrants in 2028, Chevrolet and Honda now have a new and exciting opportunity to build on their incredible legacies across IndyCar Series racing, while continuing their strong relationships with our current roster of teams and helping deliver an innovative and industry leading new car in 2028,” Boles said.
