So it’ll be one more year for IndyCar’s Dallara DW12 chassis, which has already been in service for 14 years, certainly making it the oldest platform used in a major auto racing series.
IndyCar had promised that a new car would debut for the 2027 season, but that has been postponed until at least 2028, according to the Indianapolis Star and Racer.com. Why? Not so much because the car itself couldn’t be ready, but because engine suppliers Honda and Chevrolet need more time to develop upgraded powerplants, which include a new engine and energy recovery system.
According to Racer, the two companies need at least 18 months to build and test 50 new engines each, the quantity that is required to supply the series. Apparently, the Roger Penske–owned IndyCar series has yet to give Chevrolet and Honda a final draft of the rules governing the new engines.
The current formula—a 2.2-liter, twin-turbocharged V-6, used by both Honda and Chevrolet—dates back to 2012. A hybrid system was added late last season and has earned mixed reviews from drivers and teams.
Current supplier Dallara will also build the new car, currently called the IR-27. It’s unclear if it will be renamed the IR-28 … or beyond.
