The NTT IndyCar Series has selected Ilmor Engineering as the service provider for its upcoming energy recovery systems (ERS) and enclosures. Ilmor Engineering, known for manufacturing Chevrolet’s IndyCar motors, will assemble and distribute the ERS units, which will be treated as a spec component. The ERS units will be leased and distributed randomly to teams, similar to engines, and will have serial numbers to track their mileage. The ERS bellhousings will be returned to Ilmor for exchange when necessary, with teams removing their parts before trading for a fresh bellhousing. The lease price and mileage targets for the ERS units are still being worked on, but the goal is for each unit to reach 5000 miles before a rebuild is required. The ERS units are expected to be used during the first months of 2024 as teams conduct hybrid testing. The next step is to build and begin track testing with the final specification units intended for racing next summer.
