IndyCar has announced that both Honda and Chevrolet have made a multi-year commitment to remain involved with the race series.
Both companies will continue as official Original Equipment Manufacturers (OEMs) to the NTT IndyCar Series, supplying engines for the 2027 season and beyond.
The new commitment means the OEMs will provide teams with 2.2-liter turbocharged V-6 engines – now combined with a low-voltage hybrid system since the 2024 season – until the end of 2027.
In addition, Honda and Chevrolet will play pivotal roles in developing the next generation of IndyCar engines.
The plan is for a bespoke 2.4-liter twin-turbocharged V-6 with hybrid assistance, which will join an all-new replacement chassis for 2028.
Charter agreements for Honda and Chevrolet
As a reward for the financial investment from Honda and Chevrolet, IndyCar will grant both OEMs their own single-car team charter for the 2028 season and beyond.
This allows each manufacturer to field an individual factory entry in the IndyCar series. The OEMs will likely partner with an existing team, but with greater involvement in how their cars will be operated.
Rewarding OEMs with their own team charters is also seen as a way to encourage a third engine supplier to enter the series.
“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,” said IndyCar president, Doug Boles.
“A monumental day for Indycar”
“This is a monumental day for IndyCar, fueled by a massive and historic commitment from two of our best and most trusted partners,” added 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.”
Honda has participated in the IndyCar Series since 1994, acting as the sole engine supplier for the championship between 2006 and 2011. In recent years, Honda has powered Alex Palou to all four of his Drivers’ Championships.
Making its return to IndyCar racing in 2012, Chevrolet has since collected nine championship trophies, plus multiple Indianapolis 500 wins.
The 18-round 2026 NTT IndyCar Series begins on Sunday 1 March 2026, with the Firestone Grand Prix of St. Petersburg in Florida.
