The Acura AR24eengine is a twin-turbocharged, four-stroke, 2.4-liter, V6 racing engine, made by Honda Racing Corporation USA (HRC US) for use in their Acura ARX-06 LMDh race car, since 2023. [1]
Honda Performance Development, now Honda Racing Corporation USA, developed the bespoke engine for the new-for-2023 ARX-06 LMDh featuring the smallest displacement that HRC US has made for an endurance racing engine. Optimizations include the 90° V-angle, to reduce the center of gravity of the engine and the combustion chamber can use sustainable low-carbon fuel. [2] [3] In accordance with the LMDh rules, the AR24e internal combustion engine is connected to the standardized hybrid drivetrain components provided by Bosch (motor generator unit), Williams Advanced Engineering (battery pack), and an Xtrac P1359 gearbox.
